<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are registering for resale pursuant to this prospectus 19,875 shares of
our common stock that we have issued pursuant to an Asset Purchase Agreement,
dated effective as of May&nbsp;1, 2003, among us, Addax Sound Company, a Delaware
corporation, and the stockholders of Addax. Pursuant to the Asset Purchase
Agreement, we acquired substantially all of the assets of Addax, a developer
and manufacturer of hands-free communication devices, including proprietary
headsets and off-the-body communication systems. Under the Asset Purchase
Agreement, we issued 19,875 shares of our common stock to Addax for immediate
subsequent distribution to the stockholders of Addax as consideration for the
acquisition of the assets of Addax. We are registering 19,875 shares of our
common stock for resale under this prospectus to cover the 19,875 shares
referred to above. The selling stockholders can use this prospectus to sell
some or all of the shares of our common stock they received pursuant to the
Asset Purchase Agreement.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although we will not receive any of the proceeds from the selling
stockholders&#146; sale of their shares, we have agreed to and will pay for the
costs of registering the shares covered by this prospectus, other than
commissions, fees and discounts of underwriters, brokers, dealers and agents,
if any.

<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">We market a line of products used by consumers to listen to music. We
distribute these products through retail channels in the U.S. and independent
distributors throughout the rest of the world. We are dependent upon our
ability to retain an existing base of customers to sell our line of products.
Loss of customers means loss of product placement. We have broad distribution
across many channels including specialty stores, mass merchants, electronics
stores and computer retailers. Since distribution is broadly based, any loss
of a customer directly translates into a reduction in sales volume which can
only be replaced by replacing a similar number of representative retail
outlets. The inability of our sales and marketing staff to obtain new
distribution outlets translates into a lack of future growth and possibly a
setback in sales volumes when loss of current customers occurs. For example,
the loss of a customer representing 10% of the company&#146;s business would
translate into a reduction in revenues of up to 10% based upon the point
through the fiscal year that the customer was lost. Attracting a new customer
during the course of a fiscal year could have a positive impact or simply
replace an account which has been lost. In addition, a customer can decide to
make a change in the models that it decides to offer for sale. Such changes
can take place arbitrarily throughout the course of a year which can cause
reductions in sales revenues in proportion to the number of retail outlets that
the store represents in the market. We may not be able to maintain customers
or model selections and therefore experience a reduction in its sales revenue
until a model is restored to the mix or a customer is replaced by a new
customer. A reduction in sales volume would cause a reduction in
profitability. Our failure to retain existing customers, obtain new customers
or develop new product lines that customers would choose to offer to consumers
could significantly affect our future profitability. The loss of business of
one or more principal customers or a change in the sales volume from a
particular customer could have a material adverse effect on our sales volume
and profitability.

<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">We sell a line of products with a suggested retail price ranging from less than
$10 dollars US to $1000 dollars US. The gross margin for each of these models
is unique in terms of percentages. The price range of the products also
produces a different level of actual dollar contribution per unit. For example
a product with a gross margin contribution of 50% might yield a $5.00
contribution for one item, while another item may feature a 30% gross margin
which could yield $50.00 dollars. We find the low priced portion of the market
most competitive and therefore most subject to pressure on gross margin
percentages which tends to lower profit contributions. Retail preference for
lower priced items can reduce profit margins and contributions. The risk is
that a shift in retail customer specifications toward lower priced items can
lead to lower gross margins and lower profit contributions per unit of sale.
Due to the range of products that we sell, the product sales mix can produce a
variation in terms of a range of profit margins. Some customers a sell limited
range of products that yield lower profit margins than others. Most notably,
the budget priced headphone segment of the market below $10.00 retail which is
distributed through computer stores, office supply stores, and mass market
retailers tend to yield the lowest gross margins. An increase in business with
these types of accounts, when coupled with a simultaneous reduction in sales to
customers with higher gross margins will reduce profit margins and
profitability.

reduction in model offerings and to out of stock situations. If a retail
customer of the company does not have adequate stocks of our products to offer

instead. Customers operating retail stores anticipate future sales demands and

affected by these circumstances, how extensive the effects may be, or for how

changes in economic conditions and any anticipated changes in economic
conditions can therefore restrict product placement, availability, sales,

compete with other manufacturers to secure shelf space in retail stores for our
products. During the course of a year changes in the customers management
personnel can ultimately lead to changes in the stock assortment offered to
consumers. These changes are often arbitrary. The sales and marketing team
cannot always overcome such decisions. In addition to changes in personnel
within our customers, it is also possible that a strategic decision can be made
by a retail customer to consolidate vendors, or to discontinue certain product
categories all together. In these instances our management team is not able to
overcome such decisions. Our management team is also engaged in the effective
procurement, assembly, and manufacture of products. The ability to negotiate
with suppliers, maintain productivity, and hold the line on cost increases can
be subjected to pressures outside the control of management. For example,
increases in fuel costs can increase rates in freight. Increases of this
nature can seldom be avoided and the company is not able to pass such increases
along to its customers. Our management&#146;s effective control of the
manufacturing processes will have a direct impact on our future
profitability. We regularly make decisions that affect production schedules,
shipping schedules, employee level, and inventory levels. Our ability to make
effective decisions in managing these areas has a direct effect on future
profitability.

</TABLE>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">We have significant accounts receivable or other amounts due from our customers
or other parties. The accounts receivable balance at the end of the last 4
quarters averaged approximately eight million dollars US. Terms of payment for
customers range from cash in advance to net 90&nbsp;day credit terms. These credit
arrangements are negotiated at unspecified and irregular intervals. The largest
customers generate the largest receivable balances. If a customer develops
operational difficulty it is not uncommon to temporarily suspend payment to
vendors. The company is not immune from such practice in the retail
marketplace. From time to time a customer may develop severe operating losses
which can trigger a bankruptcy. In these cases, we loose most of the
outstanding balance due. Occasionally we have been current with a customer at
the time such an event occurs. The risk is that loosing the revenue of the
customer in the future after a re-structure, might be more onerous than loosing
the current outstanding debt. We are not immune from making such decisions.
In addition, many companies that will insure accounts receivables will not do
so for our largest mass market customers. The best example of such a loss was
KMART Corporation. We lost approximately $500,000 when KMART filed for
re-organization. KMART had been current with us at the time that KMART filed
Chapter&nbsp;11 bankruptcy. We continued to supply KMART during its post petition
re-organization and continue to supply the customer profitably today. The risk
is that we derive most of our sales revenue and profits from selling products
to retailers for resale to consumers. The failure of our customers to pay in
full amounts due to us could negatively affect future profitability.

<P align="center" style="font-size: 10pt"><B>COMPANY PROFITS CAN SUFFER FROM INTERRUPTIONS IN SUPPLY CHAIN</B>

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We operate a small sales office in Switzerland to service the International
Export marketplace. We are aware of no material risk in maintaining this
operation. Loss of this office would result in a transfer of sales and
marketing responsibility. We use contract manufacturing facilities in Mainland
China, Taiwan, and South Korea. These independent supplier entities are
distant from us which means that we are at risk of business interruptions due
to natural disaster, war, disease, and government intervention through tariffs
or trade restrictions. We maintain a finished goods inventory level in our US
facility to mitigate this risk. The approximate level of finished goods
inventory is stocked at an average of 90&nbsp;days demand per item. Recovery of a
single facility through a replacement of supplier in the event of disaster or
suspension of supply could take approximately 120&nbsp;days. We believe that it
could restore production of its top ten selling models (which represent 76% of
the company&#146;s sales revenue) within 1&nbsp;year.

<P align="left" style="font-size: 10pt">We are also at risk if trade restrictions are introduced on our products based
upon country of origin. In addition any increase in tariffs and freight
charges would not be acceptable to pass along to our customers and would
directly impact our profits. For example, an additional increase of 5% in duty
for a complete fiscal year of purchases would amount to a reduction in pretax
profit of approximately $600,000 based upon sales reported in the company&#146;s 10K

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The shares of common stock are being registered to permit public secondary
trading of such common stock by the holders thereof from time to time after the
date of this prospectus. The sale of the common stock offered by this
prospectus may be effected from time to time directly, or by one or more
broker-dealers or agents, in one or more transactions (which may involve block
transactions) on the Nasdaq (or other national securities exchange or quotation
services on which the common stock may be listed or quoted at the time of sale)
or otherwise. Such common stock may be sold in one or more negotiated
transactions, or through a combination of such methods of distribution, at
prices based upon prevailing market prices, fixed prices, varying prices
determined at the time of sale or at negotiated prices.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To our knowledge, there are currently no plans, arrangements or
understandings between any selling stockholder and any underwriter,
broker-dealer or agent regarding the sale of our common stock by the selling
stockholders. In the event one or more broker-dealers or agents agree to sell
the common stock, they may do so by purchasing the common stock as principals
or by selling the common stock as agent for the selling stockholders. Any such
broker-dealers or agents may receive compensation in the form of discounts,
concessions or commissions from the selling stockholders or the purchasers of
the shares of common stock for which such broker-dealer or agent may act as
agent or to whom they may sell as principal, or both. There are no special
arrangements in place at this time that deviate from the standard customary
compensation for this service.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The selling stockholders will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, including Regulation&nbsp;M.
This Regulation may limit the timing of purchases and sales of our common stock
by the selling stockholders. Regulation&nbsp;M also restricts bids or purchases
made in order to stabilize the price of a security in connection with a
distribution of that security. The anti-manipulation rules under the Exchange
Act may apply to the sale of the shares in the market and to the activities of
the selling stockholders and their affiliates. These restrictions may affect
the marketability of the common stock.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Section&nbsp;145 of the General Corporate Law of the State of Delaware,
we have broad power to indemnify our directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act. Section&nbsp;6.01 of our bylaws also provide for indemnification of our
directors, officers, employees and agents, if such person acted in good faith
and in a manner believed to be in and not opposed to our best interests, and,
with respect to any criminal action or proceeding, the indemnified party had no
reason to believe his or her conduct was unlawful.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VIII of our restated certificate of incorporation provides that
the liability of our directors for monetary damages shall be indemnified in
accordance with and to the fullest extent permissible under Delaware law.
Pursuant to Delaware law, and our restated certificate of incorporation, this
includes elimination of liability for monetary damages for breach of the
directors&#146; fiduciary duty to us and our stockholders. These provisions do not

<P align="left" style="font-size: 10pt">eliminate the directors&#146; duty of care and, in appropriate circumstances,
equitable remedies such as injunctive or other forms of non-monetary relief
will remain available under Delaware law. In addition, each director will
continue to be subject to liability for breach of the director&#146;s duty of
loyalty to us, for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for any transaction from which the
director derived an improper personal benefit, and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision also does not affect a director&#146;s responsibilities under
any other laws, such as the federal securities laws or state or federal
environmental laws.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors, officers and controlling persons
pursuant to the foregoing provisions, or otherwise, we have been advised that
in the opinion of the SEC such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have obtained a policy of directors&#146; and officers&#146; liability insurance
that insures our directors and officers against the cost of defense, settlement
or payment of a judgment up to certain limits. For example, the policy limit
for defense costs is $10,000,000 and is part of, and not in addition to, the
overall limits of liability for the policy and such defense costs reduce and
may exhaust the maximum limits of liability of the policy.

<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at
the termination of the offering.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant&#146;s annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan&#146;s annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial <I>bona
fide </I>offering thereof.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule&nbsp;14a-3 or Rule&nbsp;14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article&nbsp;3 of Regulation&nbsp;S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)&nbsp;Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
