                        KOSS CORPORATION AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                December 31, 2004

                                   (Unaudited)

1.       CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
         -------------------------------------------

         The financial statements presented herein are based on interim amounts.
         In the opinion of management, all adjustments (consisting of normal
         recurring accruals) necessary to present fairly the financial position,
         results of operations and cash flows at December 31, 2004 and for all
         periods presented have been made. All significant intercompany
         transactions have been eliminated. The income from operations for the
         quarter ended December 31, 2004 is not necessarily indicative of the
         operating results for the full year in 2004.

         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, 2004 Annual Report
         on Form 10-K.

2.       EARNINGS PER COMMON SHARE
         -------------------------

         Basic earnings per common 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 December
         31, 2004 and 2003 were 3,692,970 and 3,767,929, respectively. For the
         six months ended December 31, 2004 and 2003, weighted average number of
         common shares outstanding were 3,856,895 and 3,767,011, respectively.
         When dilutive, stock options are included as share equivalents using
         the treasury stock method. Common stock equivalents of 132,392 and
         115,523 related to stock option grants were included in the computation
         of the average number of shares outstanding for diluted earnings per
         common share for the quarters ended December 31, 2004 and 2003,
         respectively. Common stock equivalents of 147,380 and 126,021 related
         to stock option grants were included in the computation of the average
         number of shares outstanding for diluted earnings per common share for
         the six months ended December 31, 2004 and 2003, respectively.

4.       STOCK PURCHASE AGREEMENT
         ------------------------

          The Company has an agreement with its Chairman, John C. Koss, to, at
          the request of the executor of the estate, repurchase Company common
          stock from his estate in the event of his death. The Company does not
          have the right to require the estate to sell stock to the Company. As
          such, this arrangement is accounted for as a written put option with
          the fair value of the put option recorded as a derivative liability.
          The fair value of the option at December 31, 2004 was $125,000. The
          repurchase price is 95% of the fair market value of the common stock
          on the date that notice, if the estate elects, to repurchase is
          provided to the Company. Under the agreement, the total number of
          shares to be repurchased will be sufficient to provide proceeds which
          are the lesser of $2,500,000 or the amount of estate taxes and
          administrative expenses incurred by the Chairman's estate. The Company
          may elect to pay the purchase price in cash or may elect to pay cash
          equal to 25% of the total amount due and to execute a promissory note
          for the balance, payable over four years, at the prime rate of
          interest. The Company maintains a $1,150,000 life insurance policy to
          fund a substantial portion of this obligation. At December 31, 2004
          and June 30, 2004, $125,000 has been classified as a derivative
          liability on the Company's financial statements.

          During May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
          Financial Instruments with Characteristics of both Liabilities and
          Equity," which establishes standards for the classification and
          measurement of certain financial instruments with characteristics of
          both liabilities and equity. The Company adopted SFAS No. 150
          effective July 1, 2003. Upon adoption, the Company recorded a
          derivative liability for the fair value of a written put option of
          $125,000 on the balance sheet and a cumulative effect of change in
          accounting principle of $75,875 (net of the tax effect equal to
          $49,125) on the income statement.

5.        DIVIDENDS DECLARED
          ------------------

          On December 15, 2004, the Company declared a quarterly cash dividend
          of $0.13 per share for stockholders of record on December 31, 2004 to
          be paid January 14, 2005. Such dividend payable has been recorded at
          December 31, 2004.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.

Financial Condition, Liquidity and Capital Resources
----------------------------------------------------

Cash provided by operating activities during the six months ended December 31,
2004 amounted to $5,271,599. This was primarily a result of net income for the
period and changes in operating assets and liabilities, primarily related to
increases in accounts payable and income taxes payable.

Capital expenditures for new property and equipment (including production
tooling) were $818,116 for the six months ended December 31, 2004. Budgeted
capital expenditures for fiscal year 2005 are $1,611,860. The Company expects to
generate sufficient funds through operations to fund these expenditures.

Stockholders' investment decreased to $20,231,794 at December 31, 2004, from
$21,089,787 at June 30, 2004. The decrease reflects the effect of the purchase
and retirement of common stock and dividends declared and paid, offset by net
income and the exercise of stock options.

The Company amended its existing credit facility in November 2004, extending the
maturity date of the unsecured line of credit to November 1, 2005. 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 common stock pursuant to the Company's common stock repurchase program.
Borrowings under this credit facility bear interest at the bank's prime rate, or
LIBOR plus 1.75%. This



                                    7 of 16


<PAGE>


credit facility includes 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 December 31, 2004
or June 30, 2004. The Company did not utilize the credit facility during the
quarter ended December 31, 2004.

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. Subsequently, the Board of directors
periodically has approved increases in the stock repurchase program. The most
recent increase was for an additional $2,000,000 in October 2004, for a maximum
of $40,500,000. 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.

For the six months ended December 31, 2004, the Company purchased 94,250 shares
of its common stock at an average net price of $22.61 per share, for a total net
purchase price of $2,130,625.

From the commencement of the Company's stock repurchase program through December
31, 2004, the Company has purchased a total of 5,259,084 shares for a total
gross purchase price of $42,786,170, (representing an average gross purchase
price of $8.14 per share) and a total net purchase price of $38,160,685
(representing an average net purchase price of $7.26 per share). The difference
between the total gross purchase price and the total net purchase price is the
result of the Company purchasing from 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 by the Company
for all stock purchases, as authorized by the Board of Directors.

The Company also has an Employee Stock Ownership Plan 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 six months ended
December 31, 2004 the ESOP purchased 1,502 of the Company's stock.

Results of Operations
---------------------

Net sales for the second quarter ended December 31, 2004 rose 4% to $10,225,079
from $9,839,572 for the same period in 2003. Net sales for the six months ended
December 31, 2004 were $19,197,659 up 1% compared with $19,004,263 during the
same six months one year ago. This increase in net sales was primarily due to
increases in export sales, most notably to Europe.

Gross profit as a percent of net sales was 39% for the quarter ended December
31, 2004 compared to 38% for the same period in the prior year. For the six
month periods ended December 31, 2004 and 2003, the gross profit percentage was
38%.

Selling, general and administrative expenses for the quarter ended December 31,
2004 were $2,456,825 or 24% of net sales, compared to $1,972,115 or 20% of net
sales for the same period in 2003. For the six month period ended December 2004,
these expenses were $4,576,346 or 24% of net sales, compared to $4,001,849 or
21% of net sales, for the same period in 2003. This was due to the Company
experiencing higher marketing expenses in preparation for the Consumer
Electronics Show held in January 2005.

For the second quarter ended December 31, 2004, income from operations was
$1,501,793 versus $1,769,885 for the same period in the prior year. Income from
operations for the six months ended December 31, 2004 was $2,805,245 as compared
to $3,237,796 for the same period in 2003. This was due to the Company
experiencing higher selling, general and administrative expenses.

Royalty income for the quarter ended December 31, 2004 was $484,614, compared to
$387,367 for the quarter ended December 31, 2003. For the six month period ended
December 31, 2004 royalty income


                                    8 of 16


<PAGE>

was $636,070 compared to $577,692 for the period ending December 31, 2003. The
increase in royalty income was due to increased sales by Jiangsu Electronics.
However, effective November 23, 2004, the Company terminated the License
Agreement dated November 15, 1991, and as subsequently amended (the "License
Agreement") between the Company and Jiangsu Electronics Limited of Hong Kong
("Jiangsu"). As a result of the termination, other than Jiangsu's
post-termination right to sell Company-approved licensed products, as set forth
in the License Agreement, Jiangsu no longer has the right to use certain Company
trademarks in connection with the manufacture, marketing and distribution of
Jiangsu's products under the License Agreement. Royalty income on all previously
approved products, which are already in the pipeline, will still be owed to the
Company. The Company believes that the immediate impact on our fiscal year will
be approximately $170,000 in net income or $0.05 per share. The Company also
forecasts the possible reduction of its minimum royalty payments for fiscal year
2006 at $0.09 per share.

Interest income for the quarter was $12,678 as compared to $701 for the same
quarter in 2003. For the six month period interest income was $16,876 compared
to $5,121.

The provision for income taxes for the quarter ended December 31, 2004, was
$779,643 compared with $861,517 for the same period last year. For the six
months ended December 31, 2004, the provision for income taxes was $1,348,838
compared with $1,503,669 for the same period last year. The effective tax rate
was 39% for each of the quarters.

Recently Issued Financial Accounting Pronouncements
---------------------------------------------------

During May 2003, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 150, "Accounting for
Certain Financial Instruments with Characteristics of both Liabilities and
Equity," which establishes standards for the classification and measurement of
certain financial instruments with characteristics of both liabilities and
equity. The Company adopted SFAS No. 150 effective July 1, 2003. Upon adoption
the Company recorded a derivative liability for the fair market value of a
written put option of $125,000 and a cumulative effect of change in accounting
principle of $75,875 (net of the tax effect equal to $49,125) in the income
statement.

During December 2004, the FASB issued Revised SFAS No. 123, "Share-Based
Payment," which establishes standards for the accounting for transactions in
which an entity exchanges its equity instruments for goods or services, focusing
primarily on accounting for transactions in which an entity obtains employee
services in share-based payment transactions. Revised SFAS No. 123 also
addresses transactions in which an entity incurs liabilities in exchange for
goods or services that are based on the fair value of the entity's equity
instruments or that may be settled by the issuance of those equity instruments.
We are in the process of determining the impact of Revised SFAS No. 123 on our
consolidated financial statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

In management's opinion, the Company does not engage in any material risk
sensitive activities and does not have any market risk sensitive instruments,
other than the Company's commercial credit facility used for working capital
purposes and stock repurchases as disclosed on page 8 of this Form 10-Q.

ITEM 4.  CONTROLS AND PROCEDURES.

The Company's management, including the Chief Executive Officer/Chief Financial
Officer, evaluated the Company's disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period
covered by this report and concluded that the Company's disclosure controls and
procedures are effective to provide reasonable assurance that information
required to be disclosed by the Company in the reports that it files or submits
under the Exchange Act is accumulated and communicated to management, including
the Chief Executive Officer/Chief Financial Officer, to


                                    9 of 16


<PAGE>

allow timely decisions regarding required disclosure and are effective to
provide reasonable assurance that such information is recorded, processed,
summarized and reported within the time periods specified by the SEC's rules and
forms.

There has been no change in the Company's internal control over financial
reporting that occurred during the quarter covered by this report that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
