KOSS CORPORATION AND SUBSIDIARIES September 30, 2001 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS The financial statements presented herein are based on interim amounts. 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, 2001 and for all periods presented have been made. The income from operations for the quarter ended September 30, 2001 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, 2001, 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, 2001 and 2000 were 1,917,806 and 2,236,893, respectively. When dilutive, stock options are included as share equivalents using the treasury stock method. Common stock equivalents of 123,889 and 90,956 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, 2001 and 2000, respectively. On October 2, 2001, the Company issued a Press Release declaring a 2 for 1 split of the Company's common stock for stockholders of record on October 22, 2001 with the effective date being November 5, 2001. Had this stock split been effective prior to September 30, 2001, the number of outstanding common shares would have increased to 3,679,054 and earnings per common share basic and diluted for the quarters ending September 30, 2001 and 2000, on a pro forma basis would have been as follows: September 30 2001 2000 ------------------------------------ Basic $ 0.27 $ 0.31 Diluted $ 0.25 $ 0.30 Subsequent to the effective date of this common stock split all historical earnings per common share amounts disclosed in the future will be restated to give effect to this common stock split. 6 of 14

3. INVENTORIES The classification of inventories is as follows: September 30, 2001 June 30, 2001 -------------------------------------------------------------------------------- Raw materials and work in process $ 2,439,787 $ 3,064,147 Finished goods 6,539,387 6,412,881 -------------------------------------------------------------------------------- 8,979,174 9,477,028 LIFO Reserve (981,018) (981,018) -------------------------------------------------------------------------------- $ 7,998,156 $ 8,496,010 ================================================================================ 4. STOCK PURCHASE AGREEMENT The Company has an agreement with its Chairman to repurchase stock from his estate in the event of his death. The repurchase price is 95% of the fair market value of the 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, 2001 and June 30, 2001, $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. RECLASSIFICATIONS Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. 6. NEW ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (FAS) No. 141, "Business Combinations" and No. 142, "Goodwill and Other Intangible Assets." The statements eliminate the pooling-of-interests method of accounting for business combinations and require that goodwill and certain intangible assets not be amortized. Instead, these assets will be reviewed for impairment annually with any related losses recognized in earnings when incurred. The statements will be effective for the Company as of July 1, 2002 for existing goodwill and intangible assets and for business combinations initiated after June 30, 2001. The Company is currently analyzing the impact these statements will have; however, the impact is not expected to be material on the Company's financial position or results of operations. 7 of 14

In July 2001, the FASB also 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. The statements are effective for the Company July 1, 2002. The Company is currently analyzing the impact these statements will have; however, the impact is not expected to be material on the Company's financial position or results of operations. In April 2001, the EITF reached a consensus on EITF Issue No. 00-25, "Accounting for Consideration from a Vendor to a Retailer in Connection with the Purchase or Promotion of the Vendor's Products." This issue requires that consideration from a vendor to a retailer (a) in connection with the retailer's purchase of the vendor's products or (b) to promote sales of the vendor's products by the retailer be classified as a reduction of net sales unless the consideration meets certain criteria. EITF No. 00-25 is effective for the Company's fiscal quarters beginning after December 15, 2001 and requires reclassification of prior periods. The Company is currently evaluating the impact of implementing EITF No. 00-25. 7. SUBSEQUENT EVENT On October 29, 2001, the Company declared a quarterly cash dividend of $0.12 per share for stockholders of record on December 31, 2001 to be paid January 15, 2002, which dividend reflects the effect of the 2 for 1 stock split referenced in the Company's October 2, 2001 Press Release. 8 of 14

KOSS CORPORATION AND SUBSIDIARIES FORM 10-Q - September 30, 2001 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, 2001 amounted to $971,496. This was a result of net income for the period offset by changes in operating assets and liabilities, primarily related to increases in accounts receivable and income taxes payable and decreases in inventories and accounts payable. Capital expenditures for new property and equipment (including production tooling) were $158,820 for the quarter. Budgeted capital expenditures for fiscal year 2002 are $1,239,865. The Company expects to generate sufficient funds through operations to fund these expenditures. Stockholders' investment decreased to $11,383,975 at September 30, 2001, from $14,939,429 at June 30, 2001. The decrease reflects the effect of net income, the purchase and retirement of common stock, the purchases of common stock for treasury, dividends declared and not paid, and the exercise of stock options for the quarter. The Company amended its existing credit facility in October 2001, extending the maturity date of the unsecured line of credit to November 1, 2002. 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. Outstanding draws on this credit facility at September 30, 2001 was $3,465,400. There was no utilization of this credit facility at June 30, 2001. 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, and an additional increase of $3,000,000 in July of 2001 for a maximum of $34,000,000. 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. 9 of 14

For the quarter ended September 30, 2001, the Company purchased 103,851 shares of its common stock at an average gross price of $40.79 per share (and an average net price of $39.71 per share), and retired all such shares except 83,851 of such shares which are being held as treasury shares. From the commencement of the Company's stock repurchase program through September 30, 2001, the Company has purchased and retired a total of 2,381,590 shares for a total gross purchase price of $37,396,245 (representing an average gross purchase price of $15.70 per share) and a total net purchase price of $33,560,472 (representing an average net purchase price of $14.09 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, 2001, the ESOP did not purchase any shares of the Company's stock. Results of Operations Net sales for the first quarter ended September 30, 2001 were $8,951,411 compared with $9,879,638 for the same period in 2000, a decrease of $928,227. This was due to slight softening of sales during July and August coupled with the loss of store traffic during the final three weeks of September, which resulted in vastly reduced retail sales that impacted automatic product replenishment. Gross profit as a percent of net sales decreased to 39% for the quarter ended September 30, 2001 compared with 40% in the prior year, as a result of a lower rate of overhead absorption from declining sales. Selling, general and administrative expenses for the quarter ended September 30, 2001 were $1,925,964 or 22% of net sales, compared to $2,049,787 or 21% of net sales for the same period in 2000. Interest expense amounted to $10,964 for the quarter as compared to $7,816 for the same period in the prior year. This increase is due to higher levels of borrowings. 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, 2002. 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 from the licensing agreement with Jiangsu was dramatically affected by the depressed market conditions resulting in a reduction in royalty payments of 43% from $293,888 for the quarter ended September 30, 2000 to $167,714 for the quarter ended September 30, 2001. 10 of 14

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. On July 25, 2001, the Company issued a Press Release declaring a quarterly cash dividend of $0.25 per share for stockholders of record on September 30, 2001 to be paid on October 15, 2001, which is recorded as dividends payable. On October 2, 2001, the Company issued a Press Release declaring a 2 for 1 stock split of the Company's common stock. The record date being October 22, 2001 and the effective date being November 5, 2001. On October 29, 2001 the Company issued a Press Release declaring a quarterly cash dividend of $0.12 per share (reflecting the effect of the 2 for 1 stock split) payable on January 15, 2002 to shareholders of record on December 31, 2001. New Accounting Pronouncements In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (FAS) No. 141, "Business Combinations" and No. 142, "Goodwill and Other Intangible Assets." The statements eliminate the pooling-of-interests method of accounting for business combinations and require that goodwill and certain intangible assets not be amortized. Instead, these assets will be reviewed for impairment annually with any related losses recognized in earnings when incurred. The statements will be effective for the Company as of July 1, 2002 for existing goodwill and intangible assets and for business combinations initiated after June 30, 2001. The Company is currently analyzing the impact these statements will have; however, the impact is not expected to be material on the Company's financial position or results of operations. In July 2001, the FASB also 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. The statements are effective for the Company July 1, 2002.
