         In the opinion of management, all adjustments (consisting only of
         normal recurring accruals) necessary to present fairly the financial
         position, results of operations and cash flows at September 30, 2002
         and for all periods presented have been made. The income from
         operations for the quarter ended September 30, 2002 is not necessarily
         indicative of the operating results for the full year.

         Certain information and footnote disclosures normally included in
         financial statements prepared in accordance with accounting principles
         generally accepted in the United States of America have been condensed
         or omitted. It is suggested that these condensed consolidated financial
         statements be read in conjunction with the financial statements and
         notes thereto included in the Registrant's June 30, 2002, Annual Report
         on Form 10-K.

2.       EARNINGS PER COMMON SHARE AND STOCK SPLIT

         Basic earnings per share are computed based on the weighted average
         number of common shares outstanding. The weighted average number of
         common shares outstanding for the quarters ending September 30, 2002
         and 2001 were 3,855,625 and 3,835,612, respectively. When dilutive,
         stock options are included as share equivalents using the treasury
         stock method. Common stock equivalents of 185,071 and 123,889 related
         to stock option grants were included in the computation of the average
         number of shares outstanding for diluted earnings per share for the
         quarters ended September 30, 2002 and 2001, respectively.

         On October 2, 2001, the Company declared a 2 for 1 stock split of the
         Company's common stock for stockholders of record on October 22, 2001,
         with the effective date being November 5, 2001. Earnings per common
         share amounts disclosed have been restated to give effect to the common
         stock split.

4.       STOCK PURCHASE AGREEMENT

         The Company has an agreement with its Chairman to repurchase stock from

                                     6 of 19
<PAGE>


         common stock on the date that notice to repurchase is provided to the
         Company. The total number of shares to be repurchased shall be
         sufficient to provide proceeds which are the lesser of $2,500,000 or
         the amount of estate taxes and administrative expenses incurred by his
         estate. The Company is obligated to pay in cash 25% of the total amount
         due and to execute a promissory note at the prime rate of interest for
         the balance. The Company maintains a $1,150,000 life insurance policy
         to fund a substantial portion of this obligation. At September 30, 2002
         and June 30, 2002, $1,490,000 has been classified as a Contingently
         Redeemable Equity Interest reflecting the estimated obligation in the
         event of execution of the agreement.

5.       NEW ACCOUNTING PRONOUNCEMENTS

         In July 2001, the FASB issued FAS No. 143, "Accounting for Asset
         Retirement Obligations" and in August 2001, issued No. 144, "Accounting
         for the Impairment or Disposal of Long-Lived Assets." FAS No. 143
         establishes accounting standards for the recognition and measurement of
         an asset retirement obligation. FAS No. 144 addresses financial
         accounting and reporting for the impairment or disposal of long-lived
         assets, superseding FAS No. 121. SFAS No. 143 and SFAS No. 144 was
         effective for the Company on July 1, 2002. The statements did not have
         an impact on the Company's results of operations or financial position.

         In November 2001, the EITF reached a consensus on EITF No. 01-9,
         "Accounting for Consideration Given by a Vendor to a Customer or a
         Reseller of the Vendor's Products." This issue addresses various
         aspects of the accounting for consideration given by a vendor to a
         customer or reseller of the vendor's products and was effective for the
         Company's fiscal quarter ended March 31, 2002. The implementation of
         this issue did not have a material impact on the Company's results of
         operations for the quarter ended September 30, 2002.

         In June 2002, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 146, "Accounting for Exit or
         Disposal Activities." This statement addresses the recognition,
         measurement, and reporting of costs associated with exit and disposal
         activities, including restructuring activities. The scope of the
         current statement also includes (1) costs related to a termination
         contract that is not a capital lease and (2) termination benefits that
         employees who are involuntarily terminated receive under the terms of a
         one-time benefit arrangement that is not an ongoing benefit arrangement
         or an individual deferred-compensation contract. SFAS No. 146 will be
         effective for exit or disposal activities that are initiated after
         December 31, 2002. The Company is currently evaluating the impact of
         SFAS No. 146.

 6.       DIVIDENDS DECLARED

          On September 23, 2002, the Company declared a quarterly cash dividend
          of $0.13 per share for stockholders of record on September 30, 2002 to
          be paid October 15, 2002, such dividend payable has been recorded at
          September 30, 2002.

                        KOSS CORPORATION AND SUBSIDIARIES
                         FORM 10-Q - September 30, 2002
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Financial Condition and Liquidity

Cash provided by operating activities during the three months ended September
30, 2002 amounted to $1,242,431. This was a result of net income for the period
adjusted for changes in operating assets and liabilities, primarily related to
increases in inventories, accounts payable and income taxes payable and
decreases in accounts receivable.

Capital expenditures for new property and equipment (including production
tooling) were $106,993 for the quarter. Budgeted capital expenditures for fiscal
year 2003 are $1,082,000. The Company expects to generate sufficient funds
through operations to fund these expenditures.

Stockholders' investment increased to $13,896,352 at September 30, 2002, from
$13,272,746 at June 30, 2002. The increase reflects the effect of net income and
dividends.

The Company amended its existing credit facility in July 2002, extending the
maturity date of the unsecured line of credit to November 1, 2003. This credit
facility provides for borrowings up to a maximum of $10,000,000. The Company can
use this credit facility for working capital purposes or for the purchase of its
own stock pursuant to the Company's stock repurchase program. Borrowings under
this credit facility bear interest at the bank's prime rate, or LIBOR plus
1.75%. This credit facility includes certain financial covenants that require
the Company to maintain a minimum tangible net worth and specified current,
interest coverage, and leverage ratios. The Company uses its credit facility
from time to time, although there was no utilization of this credit facility at
September 30, 2002 and June 30, 2002.

In April of 1995, the Board of Directors approved a stock repurchase program
authorizing the Company to purchase from time to time up to $2,000,000 of its
common stock for its own account. In January of 1996, the Board of Directors
approved an increase in the stock repurchase program from $2,000,000 to
$3,000,000. In July of 1997, the Board of Directors again approved an increase
in the stock repurchase program from $3,000,000 to $5,000,000. In January of
1998, the Board of Directors approved an increase of an additional $2,000,000,
increasing the total stock repurchase program from $5,000,000 to $7,000,000. In
August of 1998, the Board of Directors approved an increase of $3,000,000 in the
Company's stock repurchase program, thereby increasing the total amount of stock
repurchases from $7,000,000 to $10,000,000. In April of 1999, the Board of
Directors again approved an increase in the stock repurchase program from
$10,000,000 to $15,000,000. In October of 1999, the Board of Directors increased
the stock repurchase program by another $5,000,000, up to a maximum of
$20,000,000, and in July of 2000 the Board increased the program by an
additional $5,000,000, for a maximum of $25,000,000. In January of 2001 the
Board of Directors approved an increase in the stock repurchase program from
$25,000,000 to $28,000,000, another increase in April of 2001 of an additional
$3,000,000, an additional increase of $3,000,000 in July of 2001, and an
additional $1,500,000 in April of 2002, for a maximum of $35,500,000. The
Company intends to effectuate all stock purchases either on the open market or
through privately negotiated transactions, and intends to finance all stock
purchases through its own cash flow or by borrowing for such purchases.


                                     8 of 19

From the commencement of the Company's stock repurchase program through
September 30, 2002, the Company has purchased a total of 4,856,680 shares for a
total gross purchase price of $38,577,045 (representing an average gross
purchase price of $7.94 per share) and a total net purchase price of $34,502,072
(representing an average net purchase price of $7.10 per share). The difference
between the total gross purchase price and the total net purchase price is the
result of the Company purchasing from certain employees shares of the Company's
stock acquired by such employees pursuant to the Company's stock option program.
In determining the dollar amount available for additional purchases under the
stock repurchase program, the Company uses the total net purchase price paid by
the Company for all stock purchases, as authorized by the Board of Directors.

The Company also has an Employee Stock Ownership and Trust ("ESOP") pursuant to
which shares of the Company's stock are purchased by the ESOP for allocation to
the accounts of ESOP participants. For the quarter ended September 30, 2002, the
ESOP did not purchase any shares of the Company's stock.


Results of Operations

Net sales for the first quarter ended September 30, 2002 were $8,954,978
compared with $8,951,411 for the same period in 2001, an increase of $3,567.

Gross profit as a percent of net sales stayed steady at 39% for the quarter
ended September 30, 2002 compared with 39% in the prior year.

Selling, general and administrative expenses for the quarter ended September 30,
2002 were $1,880,652 or 21% of net sales, compared to $1,925,964 or 22% of net
sales for the same period in 2001

For the first quarter ended September 30, 2002, income from operations was
$1,650,105 versus $1,525,927 for the same period in the prior year

Effective July 1, 1998, the Company entered into a License Agreement and an
Addendum thereto with Logitech Electronics Inc. ("Logitech") of Ontario, Canada
whereby the Company licensed to Logitech the right to sell multimedia/computer
speakers under the Koss brand name. This License Agreement covers North America
and certain countries in South America and Europe, requiring royalty payments by
Logitech through June 30, 2008, subject to certain minimum annual royalty
amounts.

The Company has a License Agreement with Jiangsu Electronics Industries Limited
("Jiangsu"), a subsidiary of Orient Power Holdings Limited, by way of an
assignment of a previously existing License Agreement with Trabelco N.V. Orient
Power is based in Hong Kong and has an extensive portfolio of audio and video
products. This License Agreement covers the United States, Canada, and Mexico,
and has been renewed through December 31, 2003. Pursuant to this License
Agreement, Jiangsu has agreed to meet certain minimum royalty amounts each year.
The products covered by this License Agreement include various consumer
electronics products.

Royalty income for the quarter ended September 30, 2002 was $163,961, compared
to $167,714 for the quarter ended September 30, 2001.

Interest income for the quarter was $4,279 as compared to $7,281 for the same
quarter in 2001. The decrease in interest income in 2002 is a result of lower
levels of invested excess cash.

                                     9 of 19

Interest expense amounted to $11,290 for the quarter as compared to $10,964 for
the same period in the prior year.

On September 23, 2002, the Company declared a quarterly cash dividend of $0.13
per share payable on October 15, 2002 to stockholders of record on September 30,
2002, which is recorded as dividends payable.


New Accounting Pronouncements

In July 2001, the FASB issued FAS No. 143, "Accounting for Asset Retirement
Obligations" and in August 2001, issued No. 144, "Accounting for the Impairment
or Disposal of Long-Lived Assets." FAS No. 143 establishes accounting standards
for the recognition and measurement of an asset retirement obligation. FAS No.
144 addresses financial accounting and reporting for the impairment or disposal
of long-lived assets, superseding FAS No. 121. SFAS No. 143 and SFAS No. 144 was
effective for the Company on July 1, 2002. The statements did not have an impact
on the Company's results of operations or financial position.

In November 2001, the EITF reached a consensus on EITF No. 01-9, "Accounting for
Consideration Given by a Vendor to a Customer or a Reseller of the Vendor's
Products." This issue addresses various aspects of the accounting for
consideration given by a vendor to a customer or reseller of the vendor's
products and was effective for the Company's fiscal quarter ended March 31,
2002. The implementation of this issue did not have a material impact on the
Company's results of operations for the quarter ended September 30, 2002.

In June 2002, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 146, "Accounting for Exit or Disposal
Activities." This statement addresses the recognition, measurement, and
reporting of costs associated with exit and disposal activities, including
restructuring activities. The scope of the current statement also includes (1)
costs related to a termination contract that is not a capital lease and (2)
termination benefits that employees who are involuntarily terminated receive
under the terms of a one-time benefit arrangement that is not an ongoing benefit
arrangement or an individual deferred-compensation contract. SFAS No. 146 will
be effective for exit or disposal activities that are initiated after December
31, 2002. The Company is currently evaluating the impact of SFAS No. 146.

                   CERTIFICATION OF PERIODIC FINANCIAL REPORT
            PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I, Michael J. Koss, certify that:

1.       I have reviewed this quarterly report on Form 10-Q of Koss Corporation
         (the "registrant");

2.       Based on my knowledge, this quarterly report does not contain any
         untrue statement of a material fact or omit to state a material fact
         necessary to make the statements made, in light of the circumstances
         under which such statements were made, not misleading with respect to
         the period covered by this quarterly report;

3.       Based on my knowledge, the financial statements, and other financial
         information included in this quarterly report, fairly present in all
         material respects the financial condition, results of operations and
         cash flows of the registrant as of, and for, the periods presented in
         this quarterly report;

4.       As the registrant's certifying officer I am responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant and
         have:

         a)   designed such disclosure controls and procedures to ensure that
              material information relating to the registrant, including its
              consolidated subsidiaries, is made known to us by others within
              those entities, particularly during the period in which this
              quarterly report is being prepared;

         b)   evaluated the effectiveness of the registrant's disclosure
              controls and procedures as of a date within 90 days prior to the
              filing date of this quarterly report (the "Evaluation Date"); and

         c)   presented in this quarterly report our conclusions about the
              effectiveness of the disclosure controls and procedures based on
              our evaluation as of the Evaluation Date;

5.       As the registrant's certifying officer I have disclosed, based on our
         most recent evaluation, to the registrant's auditors and the audit
         committee of registrant's board of directors (or persons performing the
         equivalent functions):

         a)   all significant deficiencies in the design or operation of
              internal controls which could adversely affect the registrant's
              ability to record, process, summarize and report financial data
              and have identified for the registrant's auditors any material
              weaknesses in internal controls; and

         b)   any fraud, whether or not material, that involves management or
              other employees who have a significant role in the registrant's
              internal controls; and

6.       As the registrant's certifying officer I have indicated in this
         quarterly report whether there were significant changes in internal
         controls or in other factors that could significantly affect internal
         controls subsequent to the date of our most recent evaluation,
         including any corrective actions with regard to significant
         deficiencies and material weaknesses.

Date:  November 4, 2002
