KOSS CORPORATION

PROXY STATEMENT

2025 ANNUAL MEETING OF STOCKHOLDERS

October 15, 2025

_______________

INTRODUCTION

THIS PROXY STATEMENT IS FURNISHED IN CONNECTION WITH THE SOLICITATION OF PROXIES BY THE BOARD OF DIRECTORS OF KOSS CORPORATION (“Koss” or the “Company”) for use at the Company’s 2025 Annual Meeting of Stockholders (together with any adjournment or postponement thereof, the “Meeting” or “Annual Meeting”) for the purposes set forth in the foregoing Notice of Annual Meeting of Stockholders.

Date, Time and Location. The Meeting will be held on Wednesday, October 15, 2025, at 8:00 a.m. Central Time. The Annual Meeting will be a virtual meeting held solely by means of remote communication. You can attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/KOSS2025, where you will be able to listen to the meeting live, submit questions and vote online. You are cordially invited to attend.

Purposes of the Meeting. At the Meeting, stockholders will consider and vote upon the following: (i) to elect five (5) directors for one-year terms; (ii) to approve, on a non-binding advisory basis, executive compensation paid to our Named Executive Officers; (iii) to ratify the appointment of WIPFLI, LLP (“WIPFLI”) as the independent registered public accounting firm for the fiscal year ending June 30, 202 6; and (iv) to transact such other business as may properly be brought before the Meeting.

Proxy Solicitation. The Board of Directors is soliciting the stockholders’ proxies, the cost of which will be borne by the Company. Proxies will be solicited primarily by mail and may be made by directors, officers and employees personally or by telephone. The Company will reimburse brokerage firms, custodians and nominees for their out-of-pocket expenses incurred in forwarding proxy materials to beneficial owners. Proxy statements, annual reports, and proxies will be mailed to stockholders on or around September 5, 2025.

Quorum and Voting Information. Only stockholders of record of the Company’s common stock (the “Common Stock”) at the close of business on August 25, 2025 (the “Record Date”) are entitled to vote at the Meeting. As of the Record Date, there were issued and outstanding 9,456,438 shares of Common Stock, each of which is entitled to one vote per share. A quorum of stockholders is necessary to take action at the Meeting. A majority of the shares of Common Stock entitled to vote, represented in person or by proxy, will constitute a quorum of stockholders at the Meeting. Votes cast by proxy or in person at the Meeting will be tabulated by the inspector of elections appointed for the Meeting. The inspector of elections will determine whether or not a quorum is present at the Meeting. Abstentions (or, with respect to the election of directors, “withhold” votes) will be treated as shares of Common Stock that are present and entitled to vote at the meeting and are therefore counted to determine a quorum. If a broker indicates on the proxy that it does not have discretionary authority to vote certain shares of Common Stock on a particular matter (a “broker non-vote”), those shares will not be considered as present and entitled to vote with respect to that matter (although those shares are considered entitled to vote for quorum purposes and may be entitled to vote on other matters).

The five nominees receiving the greatest number of votes cast in person or by proxy at the Meeting will be elected directors of the Company. The vote required to approve, by non-binding advisory basis, the compensation paid to our Named Executive Officers, to recommend to ratify the appointment of WIPFLI as the independent registered public accounting firm of the Company for the fiscal year ending June 30, 202 6, and to approve any other matter to be presented at the Meeting, is the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy at the Meeting and entitled to vote on the subject matter (unless, with respect to any other such matter, the vote of a greater number or voting by classes is required by law or the Company’s certificate of incorporation). Abstentions will have no effect on the election of directors and will have the same effect as votes “against” approval, by non-binding advisory basis, on the compensation paid to our Named Executive Officers, and the ratification of WIPFLI as the Company's independent registered public accounting firm for the fiscal year ending June 30, 202 6.

‎

A broker holding shares in “street name” for a beneficial owner has discretion (but is not required) to vote the client’s shares with respect to “routine” matters if the client does not provide voting instructions. The broker, however, is not permitted to vote the client’s shares with respect to “non-routine” matters without voting instructions. A “broker non-vote” occurs when your broker submits a proxy for your shares but does not vote on a particular proposal because the broker does not have discretionary voting power for that item and has not received instructions from you. Broker non-votes, if any, will be counted for purposes of determining a quorum. Broker non-votes will not be treated as votes cast on the election of directors and will not be treated as votes entitled to be cast thereon with respect to approval, by non-binding advisory basis, on the compensation paid to our Named Executive Officers, each of which is a “non-routine” matter, and, therefore, will have no effect on the vote required for approval of such proposals. The ratification of the appointment of WIPFLI as the Company’s independent registered public accounting firm for the fiscal year ending June 30, 2026, is considered a “routine” matter. Therefore, even if your broker does not receive voting instructions from you, your broker is entitled (but not required) to vote your shares on this proposal.

Stockholders do not have cumulative voting rights and appraisal rights are not applicable to the matters being voted upon.

Proxies and Revocation of Proxies. A proxy in the accompanying form that is properly executed, duly returned to the Company and not revoked will be voted in accordance with the instructions contained therein. In the event that any matter not described in this Proxy Statement properly comes before the Meeting, the accompanying form of proxy authorizes the persons appointed as proxies thereby (the “Proxyholders”) to vote on such matter in their discretion. At the present time, the Company knows of no other matters that are to come before the Meeting. See “TRANSACTION OF OTHER BUSINESS.” If no instructions are given with respect to any particular matter to be acted upon, a proxy will be voted “FOR” the election of all nominees for director named in this Proxy Statement, “FOR” approval of the advisory resolution on the compensation paid to our Named Executive Officers, and “FOR” the ratification of WIPFLI as the Company’s independent registered public accounting firm for the fiscal year ending June 30, 202 6. If other matters properly come before the Annual Meeting, the persons appointed to vote the proxies will vote on these matters in accordance with their best judgment.

Each such proxy granted may be revoked at any time before it is voted by filing with the Secretary of the Company a written notice of revocation, by delivering to the Company a duly executed proxy bearing a later date, or by attending the Meeting and voting online.

Annual Report and Other Information. The Company’s Annual Report to Stockholders, which includes the Company’s audited financial statements for the fiscal year ended June 30, 2025, although not a part of this Proxy Statement, is delivered herewith. We also make available on our website, www.koss.com, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. Stockholders may also obtain a copy of these reports, without charge, upon request to: Secretary, c/o Koss Corporation, 4129 North Port Washington Avenue, Milwaukee, Wisconsin 53212.

Submission of Future Stockholder Proposals and Nominations. Under certain conditions, stockholders may request that we include a proposal or director nomination at a forthcoming meeting of our stockholders in the proxy materials of the Company for such meeting. Under Exchange Act Rule 14a-8, any stockholder desiring to present a proposal to take action at the 2026 annual meeting of stockholders and include such proposal in our proxy materials must ensure that we receive the proposal, to be eligible for inclusion in our proxy statement, at our principal executive offices at 4129 North Port Washington Avenue, Milwaukee, Wisconsin 53212 no later than May 8, 2025.

To comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than Company nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than August 16, 2026.

PROPOSAL 1. ELECTION OF DIRECTORS

The By-Laws of the Company provide that the number of directors on the Board of Directors of the Company (the “Board”) will be no fewer than four and no greater than twelve. We had five directors during fiscal year 2025 and will elect five directors for fiscal year 202 6. Steven A. Leveen is not being nominated for re-election as he is retiring from the Board. Each director elected will serve until the next Annual Meeting of Stockholders and until the director’s successor is duly elected, or until his or her prior death, resignation, or removal. The five nominees that receive the most votes will be elected to serve on our Board for the next year.

Information as to the Nominees

The following identifies the nominees for the five director positions and provides information as to their business experience for the past five years. Each nominee is presently a director of the Company:

Thomas L. Doerr, 81, has been a director of the Company since 1987 and was elected Lead Director in 2015. In 1972, Mr. Doerr co-founded Leeson Electric Corporation and served as its President and Chief Executive Officer until 1982. The company manufactures industrial electric motors. In 1983, Mr. Doerr incorporated Doerr Corporation as a holding company for the purpose of acquiring established companies involved in distributing products to industrial and commercial markets. Mr. Doerr brings a wealth of entrepreneurial experience to the Board including a hands-on understanding of strategy development, operations, and finance. Mr. Doerr has been directly involved in all aspects of his businesses including operations, distribution, purchasing, finance, and quality control.

Michael J. Koss, 71, has held various positions at the Company since 1976 and has been a director of the Company since 1985. He was elected President and Chief Operating Officer of the Company in 1987, Chief Executive Officer in 1991, Vice-Chairman in 1998 and Chairman in 2015. Mr. Koss brings to the Board intimate knowledge of the Company’s daily operations as the Company’s Chief Executive Officer. In addition, Mr. Koss’s extensive senior leadership experience in various positions gives him a broad understanding of the types of operational, financial, and strategic issues that affect the Company. He has been the driving force behind the Company’s new product development. Mr. Koss concluded his service term as a director of STRATTEC Security Corporation during fiscal year 2024.

William J. Sweasy, 72, has been a director of the Company since 2015. Mr. Sweasy is Chairman of Red Wing Shoe Co., which is a multi-facility manufacturer and retailer of purpose-built footwear, setting the standard of excellence for work boots. Mr. Sweasy adds valuable experience to the Board in the areas of executive leadership, large international company experience and a diverse background in strategy development, operational management, financial oversight, and consumer goods experience.

Lenore E. Lillie, 66, has been a director of the Company since 2022. Until her retirement from Koss Corporation in 2021, Ms. Lillie held a variety of positions at the Company since 1985, and most recently, Vice President, Operations. Ms. Lillie brings to the board a broad experience in supply chain management, Asian contract manufacturing, domestic manufacturing, cost control, inventory management, pricing strategies, product development, product life cycles, shipping, and quality. Ms. Lillie adds valuable familiarity with the daily operations of the Company, including personnel issues, strategic planning, supply chain challenges, and cost challenges.

Michael J. Koss, Jr., 41, has been nominated for the fifth director position of the Company. Mr. Koss held a variety of positions at the Company since 2010, most recently serving as Vice President, Product and Marketing. Prior to working at the Company, Mr. Koss received a Master’s Degree in Business Administration (MBA) from Marquette University in 2009. Mr. Koss served on the Board of Directors of Milwaukee Film from 2016 – 2024. Mr. Koss brings to the Board a broad experience in marketing, product development, sales, finance, customer experience and strategy.

Experience, Qualifications, Attributes and Skills

The Company believes that each director nominee possesses the following experience, qualifications, attributes and skills, in addition to those reflected above, as these are required of all candidates nominated for election or reelection to the Board:

The highest level of personal and professional ethics, integrity and values;

An inquiring and independent mind;

Practical wisdom and mature judgment;

Broad training and experience at the policy-making level in business, finance and accounting, or technology;

Expertise that is useful to Koss and complementary to the background and experience of other Board members, so that an optimal balance and diversity of Board members can be achieved and maintained;

Willingness to devote the required time to carrying out the duties and responsibilities of Board membership;

For new nominees, a commitment to serve on the Board for several years to develop knowledge about Koss’s business;

Willingness to represent the best interests of all stockholders and objectively appraise management performance; and

Involvement only in activities or interests that do not conflict with the director’s responsibilities to Koss and its stockholders.

The Company expects that the “Koss Family” (Michael J. Koss, John Koss, Jr., and Michael J. Koss, Jr. and their affiliates), along with the members of the Board of Directors, who account for in the aggregate 4,189,603 shares of Common Stock outstanding as of the Record Date, will vote “for” the election of all nominees named above to the Board of Directors.

THE BOARD OF DIRECTORS RECOMMENDS THAT

STOCKHOLDERS VOTE “FOR” THE ELECTION OF ALL NOMINEES

NAMED ABOVE TO THE BOARD OF DIRECTORS.

Board Leadership Structure

The current Chairman of our Board and Chief Executive Officer is Mr. Michael J. Koss. The Company has no fixed policy with respect to the separation of the offices of the Chairman of the Board and Chief Executive Officer. Our bylaws permit these positions to be held by the same person, and the Board believes that it is in the best interests of the Company to retain flexibility in determining whether to separate or combine the roles of Chairman and Chief Executive Officer based on our circumstances. The Board has determined that it is appropriate for Mr. Koss to serve as both Chairman and Chief Executive Officer because combining the roles of Chairman and Chief Executive Officer: (1) enhances the alignment between the Board and management in strategic planning and execution as well as operational matters, (2) avoids the confusion over roles, responsibilities and authority that can result from separating the positions, and (3) streamlines board process in order to conserve time for the consideration of the important matters the Board needs to address. Further, all four of our current non-executive Board members have been deemed to be independent by our Board; therefore, we believe our Board structure provides sufficient independent oversight of our management. The Board has designated Mr. Doerr as lead independent director.

Board Committees

The Board has appointed the following standing committees for auditing and accounting matters, executive compensation, and Board nominations. Each member of these committees is an “independent director” as defined in Nasdaq Listing Rule 5605(a)(2).

Audit Committee. The Audit Committee, which was composed of Mr. Sweasy (Audit Committee Chairman), Mr. Doerr, Mr. Leveen, and Ms. Lillie, who was appointed to the Audit Committee by the Board on October 16, 2024, during the fiscal year ended June 30, 2025, reviews and evaluates the effectiveness of the Company’s financial and accounting functions, including reviewing the scope and results of the audit work performed by the independent registered public accounting firm and by the Company’s internal accounting staff. The Board has determined that Mr. Sweasy is an “Audit Committee Financial Expert” as that term is defined in Item 407(d)(5)(ii) of Regulation S-K promulgated by the Securities and Exchange Commission (the “SEC”). The Audit Committee met four times during the fiscal year ended June 30, 2025 and all current members were in attendance. The independent registered public accounting firm was present at all of these meetings to discuss their audit scope, the results of their audit and quarterly reviews. For more information about the Audit Committee meetings, see the “Audit Committee Report.” The Audit Committee is governed by a written charter, which was amended in fiscal year 2019 and approved and adopted by the Board. The amended charter is available on the Company's website. Mr. Leveen is retiring from the Board effective at the Meeting and, therefore, will not remain a member of the Audit Committee following the Meeting. The Company is not appointing another independent director to the Audit Committee following Mr. Leveen’s retirement at the Meeting.

Compensation Committee. The Compensation Committee, which was composed of Mr. Doerr (Compensation Committee Chairman), Mr. Leveen, Mr. Sweasy and Ms. Lillie, who was appointed to the Audit Committee by the Board on October 16, 2024, during the fiscal year ended June 30, 2025, has responsibility for reviewing and recommending compensation for all employees whose annual salaries exceed $150,000. The Chief Executive Officer assists the Compensation Committee with the review of compensation, which is determined based on a qualitative and quantitative review of the performance of the employee and the performance of the Company, as well as peer company data. The Compensation Committee does not use any outside consultants to make compensation decisions and retains ultimate decision-making authority for all executive pay matters. The Compensation Committee met one time during the fiscal year ended June 30, 2025. The Company’s Koss Corporation 2023 Equity Incentive Plan (the “Plan”), which was approved by the Board as well as the stockholders at the Company’s 2023 Annual Meeting, is administered by the Compensation Committee. Subject to the express provisions of the Plan, the Committee has complete authority to (i) designate individuals to whom benefits are granted and when; (ii) prescribe the terms and conditions of benefits granted; (iii) construe and interpret the Plan; (iv) promulgate, amend and rescind rules and regulations relating to the administration of the Plan; (v) accelerate, purchase, adjust or remove restrictions from benefits; and (vi) exercise discretion to make any and all other determinations which it deems to be necessary or advisable for the administration of the Plan. The Compensation Committee is governed by a written charter, which was amended in fiscal year 20 22 and approved and adopted by the Board. The charter is available on the Company's website. Mr. Leveen is retiring from the Board effective at the Meeting and, therefore, will not remain a member of the Compensation Committee following the Meeting.

Nominating Committee and Director Nomination Process. The Nominating Committee, which was composed of Mr. Doerr (Nominating Committee Chairman), Mr. Leveen, Mr. Sweasy and Ms. Lillie, who was appointed to the Audit Committee by the Board on October 16, 2024, during the fiscal year ended June 30, 2025, has responsibility for overseeing the director nomination process and for identifying and evaluating potential candidates and recommending candidates to the Board for nomination. The Nominating Committee met one time during fiscal year 2025. When the Board considers additional or replacement members, all candidates are evaluated by the Nominating Committee on the basis of outstanding achievement in their professional careers, broad experience, wisdom, personal and professional integrity and their experience with and understanding of the business environment. With respect to minimum qualifications of candidates, the Nominating Committee will consider candidates who have the experiences, skills, and characteristics necessary to gain a basic understanding of the principal operational and financial objectives and plans of the Company, the results of operations and financial condition of the Company, and the relative standing of the Company and its business segments in relation to its competitors. The Nominating Committee will consider qualified director candidates recommended by stockholders if such recommendations for director are submitted in writing to the Secretary, c/o Koss Corporation, 4129 North Port Washington Avenue,

7

Milwaukee, Wisconsin 53212 and include the following information: (i) name and address of the stockholder making the recommendation; (ii) name and address of the candidate; and (iii) pertinent biographical information about the candidate. Any nominees in support of which stockholders intend to solicit proxy must be submitted by the deadline described in the Introduction section of this Proxy Statement. The Nominating Committee does not currently have a written charter. The Board nominations are presented to and approved by the full Board.

The Nominating Committee does not have a formal diversity policy with respect to the Board, but it reviews the background and qualifications of each nominee to determine such nominee’s experience, competence, and character and assesses such nominee’s potential contribution to the Board of Directors, taking into account the then-existing composition of the Board of Directors and such other factors as the Nominating Committee deems appropriate. With respect to diversity, certain of our directors have strong technical backgrounds that are relevant to our industry; other directors have a background in management. We believe that the backgrounds and skills of our directors bring a diverse range of experience, opinions, and perspectives to the Board.

Risk Oversight

While our management is responsible for assessing and managing the risks to the Company, our Board takes an active role, as a whole and also at the committee level, in overseeing the material risks facing the Company, including operational, financial, legal and regulatory, strategic and reputational risks. Risks are considered in virtually every business decision and as part of the Company’s overall business strategy. Our Board committees also regularly engage in risk assessment as a part of their regular function. The Audit Committee discusses with management and our independent registered accounting firm the Company’s major financial risk exposures, and the steps management has taken to monitor and control such exposures. The Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Nominating Committee manages risks associated with corporate governance, including risks associated with the independence of the Board and reviews risks associated with potential conflicts of interest affecting directors and executive officers of the Company. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, our entire Board is regularly informed through committee reports about such risks. The Board regularly engages in discussion of financial, legal, technological, economic, and other risks. Because overseeing risk is an ongoing process that is inherent in the Company’s strategic decisions, our Board discusses risk throughout the year at other meetings in relation to specific proposed actions. Additionally, our Board exercises its risk oversight function in approving the annual budget and in reviewing the Company’s long-range strategic and financial plans with management.

Attendance at Board and Committee Meetings

During the fiscal year ended June 30, 2025, the Board held four meetings. Each director attended 100% of the aggregate of (i) all meetings of the Board, plus (ii) all meetings of the committees on which he or she served during the periods that he or she served.

Attendance at Annual Meetings

The Company's policy is that absent extraordinary circumstances, each member of the Board shall attend each annual stockholder meeting. Mr. Michael J. Koss, Mr. Doerr, Mr. Leveen, Mr. Sweasy and Ms. Lillie attended last year’s virtual annual meeting held on October 16, 2024.

Independence of the Board

Each of Mr. Doerr, Mr. Leveen, Ms. Lillie and Mr. Sweasy, is “independent” as such term is defined in Nasdaq Listing Rule 5605(a)(2). These independent directors constitute a majority of the Board, as required under Nasdaq Listing Rule 5605(b)(1). As Mr. Koss Jr. is not deemed to be independent, following the Annual Meeting and Mr. Leveen’s retirement, we expect that three of our five Board members will be deemed to be independent.

Communications with the Board

Stockholders may communicate with the Board, individually or as a group, by sending written communications to: Koss Corporation, 4129 North Port Washington Avenue, Milwaukee, Wisconsin 53212. Stockholders may also communicate with members of the Board by telephone (414) 964-5000 or facsimile (414) 964-8615. If any correspondence is addressed to the Board or to a member of the Board, that correspondence is forwarded directly to the Board or a member of the Board.

Code of Ethics

The Code of Ethics for the Company’s directors, officers and employees was attached as Exhibit 14 to the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, and is available on the Company’s website. In the event that the Company amends any of the provisions of, or grants a waiver under, the Code of Ethics that requires disclosure under the applicable law or SEC rules, it intends to disclose such amendment or waiver on its website.

Insider Trading Policy

The Company is committed to promoting high standards of ethical business conduct and compliance with applicable laws, rules and regulations. As part of this commitment, the Company has adopted the Insider Trading and Tipping Policy governing the purchase, sale, and/or other dispositions of the Company’s securities by its directors, officers, and employees that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and the exchange listing standards applicable to us. A copy of the Company’s Insider Trading and Tipping Policy is filed as Exhibit 19.1 to the Company’s Annual Report on Form 10-K.

Hedging Transactions

Under our Insider Trading and Tipping Policy, we prohibit our officers and directors and other participants in our equity incentive plans from engaging in hedging transactions, monetization transactions or similar arrangements involving Company securities, such as zero-cost collars and forward sale contracts.

Executive Officers

Information is provided below with respect to the executive officers of the Company. Each executive officer is appointed annually by the Board of Directors and serves for one year or until his or her successor is appointed.

Other Benefit Plans

The Company has certain benefit plans and arrangements which are available to the Named Executive Officers including the following:

Supplemental Medical Care Reimbursement Plan. Each officer of the Company is covered by a medical care insurance plan for medical expenses incurred that are not covered under the group health insurance.

Employee Stock Ownership Plan. In December 1975, the Company adopted the KESOT, which is a form of employee benefit plan designed to invest primarily in employer securities. The KESOT is qualified under Section 401(a) of the Internal Revenue Code and Michael J. Koss and Kim M. Schulte currently serve as members of the KESOT Committee. All full-time employees with at least six months of uninterrupted service with the Company are eligible to participate in the KESOT. Contributions to the KESOT are allocated to the accounts of participants in proportion to the ratio that a participant’s compensation bears to total compensation of all participants and are immediately vested. Accounts are adjusted each year to reflect the investment experience of the trust. Voting rights for all shares are passed through to the participant for whose account such shares are allocated and must be voted by the Trustees in accordance with the participants’ direction. The KESOT was amended and restated effective July 1, 2023, with no material changes except for those required by applicable laws. As of June 30, 2025, the KESOT held 308,984 shares of Common Stock (3.27% of the total number of shares outstanding).

Stock Option Plans. As of July 25, 2022, the 2012 Koss Corporation Omnibus Incentive Plan (the “Prior Plan”) expired. The Koss Corporation 2023 Equity Incentive Plan (the “2023 Plan”) was approved by the shareholders at the 2023 Annual Meeting of Stockholders and superseded and replaced the Prior Plan. Concurrently with the adoption of the 2023 Plan, the Board terminated the Prior Plan. Any awards outstanding under the Prior Plan on the date of stockholder approval of the 2023 Plan remain subject to and will be paid under the Prior Plan, and any shares subject to outstanding awards under the Prior Plan that subsequently expire, terminate, or are canceled or forfeited for any reason without issuance of shares automatically become available for issuance under the 2023 Plan.

The purposes of the 2023 Plan are to enhance our ability to attract and retain highly-competent employees, consultants, and directors, and to motivate those service providers to serve the Company and to expend maximum effort to improve our business results and earnings, by providing to those service providers an opportunity to acquire or increase a direct proprietary interest in our operations and future success of the Company.

The Compensation Committee of the Board of Directors administers the 2023 Plan and provides for the granting of various stock-based incentive awards to eligible participants, primarily officers and certain key employees of the Company. 2,000,000 shares of common stock were authorized for issuance under the 2023 Plan, plus any shares subject to awards remaining outstanding under the Prior Plan that expire or are otherwise forfeited, canceled, or terminated. The Company’s Board of Directors will determine the terms and conditions under which an option will become exercisable but expects that stock options granted under the 2023 Plan will vest over a three-to-five-year period from the date of grant. An option will expire no more than ten years from its grant date, with the exception of incentive stock options held by a 10% stockholder, which will expire no more than five years from the grant date. As with the Prior Plan, pursuant to the 2023 Plan, new shares will be issued upon exercise of stock options. As of June 30, 2025, no stock-based awards have been granted under the 2023 Plan.

Supplemental Executive Retirement Plan. The Board of Directors has by resolution entered into a Supplemental Executive Retirement Plan with Michael J. Koss which calls for Michael J. Koss to receive annual cash compensation following his retirement from the Company (“Retirement Payments”) in an amount equal to 2% of the base salary of Michael J. Koss, multiplied by his number of years of service to the Company (for example, if Michael J. Koss worked 25 years, then he would be entitled to receive 50% of his base salary). The base salary shall be calculated using the average base salary of Michael J. Koss during the three years preceding his retirement. The Retirement Payments are to be paid to Michael J. Koss monthly until his death, and after his death shall continue to be paid monthly to his surviving spouse until her death. The Company has a deferred compensation liability of $2,226,454 and $2,093,124 recorded as of June 30, 2025 and 2024, respectively, for this arrangement.

Profit Sharing Plan. Every quarter of each fiscal year, the Company sets aside a percentage of any operating profits and distributes it to all employees (except Michael J. Koss, John C. Koss, Jr., and Kim M. Schulte) based on their hourly rate of pay. All full-time Koss employees (except Michael J. Koss, John C. Koss, Jr., and Kim M. Schulte) are eligible for profit sharing if they have been employed for the complete fiscal quarter.

401(k) Plan. All employees of the Company are eligible to participate in the Company’s 401(k) Plan at the beginning of the fiscal quarter after they have completed one full fiscal quarter of service. Employees are able to defer a dollar amount up to the federal yearly maximum. In 2025, the Company matched the employee dollar deferral with a $0.25 per dollar match. In 2026, the Company also plans to match the employee dollar deferral with a $0.25 per dollar match. Such matches are completely at the discretion of the Company. The funds that are deferred and matched are immediately 100% vested to the employee’s 401(k)

12

account. The employees may allocate their funds among twenty-three investment options, or they may self-direct their funds to a qualified 401(k) of their choice.

OUTSTANDING EQUITY AWARDS AT FISCAL YEAR END

The following table sets forth information on outstanding option awards issued under the Prior Plan and held by the Named Executive Officers as of June 30, 2025, including the number of shares underlying both exercisable and un-exercisable portions of each stock option as well as the exercise price and the expiration date of each outstanding option. The Prior Plan expired on July 25, 2022 and, as such, there were no equity awards granted in fiscal year 2024 or 2023 under the Prior Plan. As further discussed below, concurrent with the termination of the Prior Plan, the 2023 Plan was approved at the 2023 Annual Meeting of the Stockholders.

All options for Michael J. Koss vested in equal annual installments over a period of four (4) years with the first 25% vesting one year after the date of grant. The options are exercisable for five (5) years and expire on the date five years from the date of grant.

(1)These options were granted on July 22, 2020 and expired unexercised.

STOCK OPTION GRANT TIMING

The Company does not have a formal policy with respect to the timing of stock option grants, however, stock options are not granted in anticipation of the release of material nonpublic information and the release of material non-public information is not timed based upon option grant dates or for the purpose of affecting the value of executive compensation. In addition, the Company does not take material non-public information into account when determining the timing and terms of stock option grants. Historically, when stock options were granted, it has been the practice of the Company to approve equity grants at its Compensation Committee meeting held annually in May. No stock options have been granted since fiscal year 2021.

THE REPORT OF THE AUDIT COMMITTEE SHALL NOT BE DEEMED INCORPORATED BY REFERENCE BY ANY GENERAL STATEMENT INCORPORATING BY REFERENCE THIS PROXY STATEMENT INTO ANY FILING UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES EXCHANGE ACT OF 1934 (TOGETHER, THE “ACTS”), EXCEPT TO THE EXTENT THAT THE COMPANY SPECIFICALLY INCORPORATES THIS INFORMATION BY REFERENCE, AND SHALL NOT OTHERWISE BE DEEMED FILED UNDER SUCH ACTS.

The Audit Committee of the Board of Directors (the “Audit Committee”) is composed of three non-employee directors. The members of the Committee are Mr. Doerr, Mr. Leveen, Ms. Lillie and Mr. Sweasy. Each member of the Audit Committee is “independent” as defined in Nasdaq Listing Rule 5605(a)(2). The Audit Committee held four meetings during the fiscal year ended June 30, 202 5. The Company appointed Ms. Lillie to the Audit Committee during the fiscal year.

The responsibilities of the Audit Committee are set forth in its Charter, which is reviewed and amended periodically, as appropriate. Generally, the Audit Committee reviews and monitors the Company’s financial reporting process on behalf of the Board of Directors. The Audit Committee operates under a written charter adopted by the Board of Directors. In fulfilling its responsibilities, the Audit Committee, among other things, monitors the integrity of the financial reporting process, systems of internal controls and financial statements and reports of the Company; appoints, compensates, retains and oversees the Company’s independent registered public accounting firm, including reviewing the qualifications, performance and independence of the independent registered public accounting firm; reviews and pre-approves all audit, attest and review services and permitted non-audit services; oversees the audit work performed by the Company’s internal accounting staff; and oversees the Company’s compliance with legal and regulatory requirements. The Audit Committee meets, at a minimum, four times a year with the Company’s independent registered public accounting firm to discuss the results of their procedures, their understanding of the Company’s internal controls and the overall quality of the Company’s financial reporting.

Specifically, the Audit Committee has:

(i) reviewed and discussed the Company’s audited financial statements for the fiscal year ended June 30, 2025, with the Company’s management;

(ii) discussed with WIPFLI LLP (“WIPFLI”), the Company’s independent registered public accounting firm, the matters required to be discussed by the Public Company Accounting Oversight Board (the “PCAOB”) Auditing Standard No. 1301, Communications with Audit Committees;

(iii) received the written disclosures and the letter from WIPFLI as required by the PCAOB regarding the independent registered public accounting firm’s communications with the audit committee concerning independence, and has discussed such matters with representatives of WIPFLI;

(iv) based on the discussions referred to above, recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, for filing with the SEC; and

(v) concluded that WIPFLI’s provision of audit and non–audit services to the Company is compatible with their independence.

Related Party Transactions

Building Lease. The Company leases its facility in Milwaukee, Wisconsin from Koss Holdings, LLC, which is controlled by five equal ownership interests in trusts held by the five beneficiaries of the former Chairman’s revocable trust and includes current stockholders of the Company. On May 24, 2022, the lease was renewed extending the expiration to June 30, 2028 (the “Extended Term”), with a second extension (“Second Extended Term”) to June 30, 2033. The lease extension maintains the rent at a fixed rate of $380,000 per year for the Extended Term with an increase to $397,000 per year for the Seconded Extended Term. The lease is being accounted for as an operating lease. The Company is responsible for all property maintenance, insurance, taxes and other normal expenses related to ownership.

Stock Repurchases. The Company has previously announced its intention to repurchase shares of Common Stock in the open market or in private transactions as such shares become available from time to time if the Company believes that its stock is undervalued and that such repurchases would enhance the value to stockholders. The Company did not repurchase any shares during the fiscal year ending June 30, 2025.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with the Commission initial reports of beneficial ownership on Form 3 and reports of changes in beneficial ownership of our equity securities on Form 4 or Form 5. The rules promulgated by the Commission under Section 16(a) of the Exchange Act require those persons to furnish us with copies of all reports filed with the Commission pursuant to Section 16(a). Based solely upon a review of such forms filed by the Company on their behalf, in addition to written representations by certain of our directors and executive officers that the required forms were filed, we believe all directors, executive officers and 10% shareholders have filed with the Commission on a timely basis all reports required to be filed under Section 16(a) of the Exchange Act during our fiscal 2025 except as noted: (1) a late Form 4 for John C. Koss, Jr. was filed June 17, 2025, covering three stock option exercises and same-day sales on June 11–13, 2025; and (2) a late Form 4 for Michael J. Koss, Jr. was also filed June 17, 2025, reporting two similar transactions on June 12 and 13, 2025, both delinquencies due to administrative oversight.

PROPOSAL 2. ADVISORY VOTE TO APPROVE EXECUTIVE OFFICER COMPENSATION

We are asking our stockholders to provide advisory approval of the compensation of our Named Executive Officers as set forth in this Proxy Statement. This vote is not intended to address any specific item of compensation or any specific Named Executive Officer, but

rather the overall compensation of all of our Named Executive Officers and the philosophy, policies and practices described in this Proxy Statement. We currently hold our Say-on-Pay vote every year.

We have designed our executive compensation program to attract and retain highly qualified, superior leaders, reward performance, and align our executives' interests with the long-term interests of our stockholders. Highlights of our program include the following:

Pay for Performance. Our incentive program incorporates a pay-for-performance relationship. A portion of our senior executives' compensation is tied to Company and individual performance. The main components of our executive compensation program are base salary and incentive awards, including both cash-based and equity-based awards. We do not provide guaranteed bonuses or stock options.

Alignment with Stockholder Interests. We promote the alignment of our executives' interests with stockholder interests by focusing on key measures of long-term value creation.

Responsible Pay Practices. Our executive compensation packages do not provide tax gross ups for our executives. In addition, we have adopted policies covering our executives that require compensation clawbacks in certain circumstances.

We believe that our executive compensation program plays a key role in our long-term success. As required by Section 14A of the Securities and Exchange Act of 1934, we request your vote supporting the following non-binding resolution:

RESOLVED: That the stockholders approve, in a non-binding vote, the compensation of the company’s Named Executive Officers as set forth in this Proxy Statement.

THE BOARD OF DIRECTORS RECOMMENDS THAT

STOCKHOLDERS VOTE “FOR” APPROVAL OF THE ADVISORY RESOLUTION

ON THE COMPENSATION PAID TO OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL 3. RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The firm of WIPFLI, LLP (“WIPFLI”) has acted as our independent registered public accounting firm to audit the consolidated financial statements of the Company and its subsidiaries for the fiscal year ending June 30, 2025. WIPFLI has served the Company as its independent registered public accounting firm since March 4, 2019. Representatives of WIPFLI are expected to be present at the Meeting, available to respond to appropriate questions and will have the opportunity to make a statement if they desire to do so.

Although this appointment of WIPFLI as the independent registered public accounting firm is not required to be submitted to a vote by stockholders, the Board believes it appropriate, as a matter of policy, to request that the stockholders ratify the appointment. If stockholder ratification (by the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy at the Meeting and entitled to vote on the subject matter) is not received, the Audit Committee of the Board will reconsider the appointment. Even if the selection of WIPFLI is ratified, the Audit Committee of the Board may, in its discretion, appoint a different firm at any time during the year if the Audit Committee feels that such a change would be in the best interests of the Company and its stockholders. Unless otherwise directed, the proxy will be voted in favor of the ratification of such appointment.

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee requires the pre-approval of all audit and permissible non-audit services provided by the Company’s independent registered public accounting firm. Under the policy, the Audit Committee is to specifically pre-approve before the filing of the Form 10-K Annual Report for the previous fiscal year any recurring audit and audit-related services to be provided during the following fiscal year. The Audit Committee also may generally pre-approve, up to a specified maximum amount, any non-recurring audit and audit-related services for the following fiscal year. All pre-approved matters must be detailed as to the particular service or category of services to be provided, whether recurring or non-recurring, and reported to the Audit Committee at its next scheduled meeting. Permissible non-audit services are to be pre-approved on a case-by-case basis. The Audit Committee may delegate its pre-approval authority to any of its members, provided that such member reports all pre-approval decisions to the Audit Committee at its next scheduled meeting. The Company’s independent registered public accounting firm and members of management are required to report periodically to the Audit Committee the extent of all services provided in accordance with the pre-approval policy, including the amount of fees attributable to such services.

In accordance with Section 10A of the Securities Exchange Act of 1934, as amended by Section 202 of the Sarbanes-Oxley Act of 2002, the Company is required to disclose the approval by the Audit Committee of non-audit services performed by the Company’s independent registered public accounting firm. Non-audit services are services other than those provided in connection with an audit or review of the financial statements. During the period covered by this filing, the Audit Committee approved all fees, and the services rendered in connection with these fees, as reported in the table shown above.

Householding of Annual Meeting Materials

SEC rules permit registrants to send a single copy of their proxy materials to any household at which two or more stockholders reside if the registrant believes they are members of the same family. This procedure, referred to as householding, reduces the volume of duplicate information stockholders receive and reduces the expense to the registrant. The Company has not implemented these householding rules with respect to its record holders; however, a number of brokerage firms have instituted householding, which may affect certain beneficial owners of Common Stock. If your family has multiple accounts by which you hold Common Stock, you may have previously received a householding notification from your broker. Please contact your broker directly if you have any questions, require additional copies of the proxy materials, or wish to revoke your decision to household, and thereby receive multiple copies of the proxy materials. Those options are available to you at any time.

TRANSACTION OF OTHER BUSINESS

The Board of Directors of the Company is not aware of any other matters that may come before the meeting. If any other matters are properly presented to the meeting for action, it is the intention of the persons named as proxies in the enclosed form of proxy to vote such proxies in accordance with their discretion on such matters.

STOCKHOLDER PROPOSALS FOR 2026 ANNUAL MEETING

There are no stockholder proposals on the agenda for the Meeting. In order to be eligible for inclusion in the Company’s proxy materials for its 2026 annual meeting, a stockholder proposal must be received by the Company no later than May 8, 2026, and must otherwise comply with the applicable rules of the SEC. To avoid controversy over when a stockholder proposal is received, stockholder proposals should be sent by certified mail, return receipt requested, and should be addressed to the Secretary of the Company.
