KOSS CORPORATION PROXY STATEMENT 2003 ANNUAL MEETING OF STOCKHOLDERS SEPTEMBER 23, 2003 ---------- INTRODUCTION THIS PROXY STATEMENT IS FURNISHED IN CONNECTION WITH THE SOLICITATION OF PROXIES BY THE BOARD OF DIRECTORS OF KOSS CORPORATION (the "Company") for use at the Company's 2003 Annual Meeting of Stockholders (the "Meeting") and any adjournment thereof, for the purposes set forth in the foregoing Notice of Annual Meeting of Stockholders. DATE, TIME AND LOCATION. The Meeting will be held at the Milwaukee River Hilton Hotel, 4700 North Port Washington Avenue, Milwaukee, Wisconsin 53212, on Tuesday, September 23, 2003, at 9:00 a.m. local time. PURPOSES OF THE MEETING. The Company is soliciting the stockholders' proxies. At the Meeting, stockholders will consider and vote upon the following: (i) the election of six (6) directors for one-year terms; (ii) a proposal to ratify the appointment of PricewaterhouseCoopers LLP ("PricewaterhouseCoopers"), independent accountants, as independent auditors for the fiscal year ending June 30, 2004; and (iii) such other business as may properly be brought before the Meeting. PROXY SOLICITATION. The cost of soliciting proxies 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 and proxies will be mailed to stockholders on approximately August 25, 2003. QUORUM AND VOTING INFORMATION. Only stockholders of record of the Company's $.005 par value common stock ("Common Stock") at the close of business on August 15, 2003 (the "Record Date") are entitled to vote at the Meeting. As of the Record Date, there were issued and outstanding 3,767,929 shares of Common Stock. Accordingly, as of the Record Date, there were 3,767,929 shares of Common Stock entitled to one vote per share. A quorum of stockholders is necessary to take action at the Meeting. A majority of the outstanding shares of Common Stock, 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. The inspector of elections will treat abstentions as shares of Common Stock that are present and entitled to vote for purposes of determining the presence of 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 six 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 ratify the appointment of PricewaterhouseCoopers as independent accountants for the year ending June 30, 2004, and to approve any other matter to be presented to 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. Abstentions and broker non-votes will have no effect on the election of directors and will have the same effect as votes "against" ratification of PricewaterhouseCoopers as the Company's auditors for the year ending June 30, 2004.

PROXIES AND REVOCATION OF PROXIES. A proxy in the accompanying form, which is properly executed, duly returned to the Company and not revoked, will be voted in accordance with instructions contained therein. In the event that any matter, which is not described in this Proxy Statement, properly comes before the Meeting, the accompanying form of proxy authorizes the persons appointed as proxies thereby ("Proxyholders") to vote on such matter in their sole discretion. At the present time, management knows of no other matters that are to come before the Meeting. See "ITEM 3. 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 herein, and "FOR" the ratification of PricewaterhouseCoopers as the Company's auditors for the year ending June 30, 2004. If matters other than those mentioned herein properly come before the Meeting, a proxy will be voted in accordance with the best judgment of a majority of the Proxyholders named therein. 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 in person. ANNUAL REPORT. The Company's Annual Report to Stockholders, which includes the Company's Form 10-K and its audited financial statements for the year ended June 30, 2003, although not a part of this Proxy Statement, is delivered herewith.

The percentage calculation assumes, for each individual owning options and for directors and executive officers as a group, the exercise of that number of stock options that are exercisable within 60 days of August 1, 2003.

To avoid double-counting: (i) the 403,243 total shares held by the KESOT and deemed to be beneficially owned by Michael J. Koss as a result of his position as a KESOT Trustee (see Note (5), above) include shares allocated to the KESOT accounts of John C. Koss, Michael J. Koss, John Koss, Jr., Ms. Sachdeva and Ms. Lillie in the above table but are included only once in the total; and (ii) the 1,217,000 shares deemed to be beneficially owned by John C.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION. John C. Koss, the President of the Company, also served as a member of the Compensation Committee during a portion f the fiscal year ended June 30, 2003. Mr. Koss is no longer serving on the Compensation Committee. DIRECTOR COMPENSATION. Directors who are not also employees of the Company receive an annual retainer of $6,000, plus $1,500 per director for each meeting, $500 per director for each committee meeting, $250 per quarter for quarters 1-3 for Audit Committee Chair to review statements with the Audit partner, and $250 per year for other Committee Chairs for service for each remaining Committee. OTHER COMPENSATION ARRANGEMENTS. The Company has certain other compensation plans and arrangements which are available to the CEO and certain of the Named Executive Officers including the following: o SUPPLEMENTAL MEDICAL CARE REIMBURSEMENT PLAN. Each officer of the Company is covered by a medical care reimbursement plan for all medical expenses incurred which are not covered under group health insurance up to an annual maximum of 10% of salary. Amounts reimbursed under this Plan are included under the column headed "All Other Compensation" in the summary compensation table. o EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST. 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. All full-time employees with at least six months' 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. Accounts are adjusted each year to reflect the investment experience of the trust and forfeitures from accounts of non-vested terminated participants. All unallocated shares will be voted by the KESOT Trustees as directed by the KESOT Committee. Michael J. Koss and Cheryl Mike currently serve as KESOT Trustees and as the members of the KESOT Committee. Voting rights for all allocated 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. As of August 1, 2003 the KESOT held 411,176 shares of Common Stock (approximately 10.51% of the total number of shares outstanding). o OFFICER LOAN POLICY. On January 31, 1980, the Board adopted an Officer Loan Policy. The significant provisions of the policy are: (i) the maximum amount to be loaned is limited to one-half of the officer's annual base salary; (ii) the first $10,000 bears no interest; (iii) in the event the loan balance exceeds $10,000, interest is charged on the entire amount at the minimum rate provided by Section 483 of the Internal Revenue Code; and (iv) the loan will be repaid in installments or in full upon termination of employment. During the fiscal year ended June 30, 2003, no officer had an officer loan that exceeded $60,000. Given the recent passage of the Sarbanes-Oxley Act of 2002, the Company will no longer have an officer loan policy. 9

o RETIREMENT AGREEMENT. Mr. Koss is eligible to receive his current base salary of $150,000 for the remainder of his life, whether he becomes disabled or not. Mr. Koss is over 70 years old and will be entitled to receive this benefit upon his retirement from the Company. The Company has a deferred compensation liability of $631,855 recorded as of June 30, 2003, and $737,599 as of June 30, 2002 for this arrangement. o STOCK OPTION PLANS. In 1990, the Board of Directors created, and the stockholders approved, a Flexible Incentive Plan (the "Plan"). This Plan is administered by the Compensation Committee and vests the Compensation Committee with discretionary powers to choose from a variety of incentive compensation alternatives to make annual stock-based awards to officers, key employees and other members of the Company's management team. o 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 Mr. 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 Mr. Koss, multiplied by his number of years of service to the Company (for example, if Mr. Koss had worked 25 years, then he would be entitled to receive 50% of base salary). The base salary shall be calculated using the average base salary of Mr. Koss during the three years preceding his retirement. The Retirement Payments are to be paid to Mr. Koss monthly until his death, and after his death shall continue to be paid monthly to his surviving spouse until her death. o 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 John C. Koss, Michael J. Koss, and John Koss, Jr.) based on their hourly rate of pay. All full-time Koss employees (except John C. Koss, Michael J. Koss, and John Koss, Jr.) are eligible for profit sharing if they have been employed for the complete fiscal quarter. Deductions are made from profit sharing for each absence (paid sick days and unpaid days) based on the number of hours of time lost. 10

AUDIT COMMITTEE REPORT The Audit Committee of the Board of Directors (the "Committee") is composed of three non-employee directors. The members of the Committee are: Mr. Mattson, Mr. Doerr and Mr. Stein. Each member of the Committee is "independent" as defined in The Nasdaq Stock Market listing standards. The Committee held two meetings during its fiscal year 2003. The responsibilities of the Committee are set forth in its Charter, which is reviewed and amended periodically, as appropriate. Generally, the Committee reviews and monitors the Company's financial reporting process on behalf of the Board of Directors. In fulfilling its responsibility, the Committee recommends to the full Board of Directors the selection of the Company's independent accountants. The Committee discusses with the independent accountants the overall scope and specific plans for their respective audits. The Committee also discusses the Company's consolidated financial statements, the effectiveness and adequacy of the Company's internal controls and pending litigation. The Committee meets twice a year with the Company's independent accountants to discuss the results of their examinations, their evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting. Specifically, the Committee has: (i) reviewed and discussed the Company's audited financial statements for the fiscal year ended June 30, 2003 with the Company's management; (ii) discussed with the Company's independent auditors the matters required to be discussed by SAS 61 (Codification of Statements on Auditing Standards); and (iii) received the written disclosures and the letter from the Company's independent accountants required by Independence Standards Board Standard No. 1 (Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees), and has discussed with the Company's independent accountants the independent accountants' independence. Based on the review and discussions referred to above, the Committee 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, 2003 for filing with the SEC. AUDIT COMMITTEE LAWRENCE S. MATTSON THOMAS L. DOERR MARTIN F. STEIN 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. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION Under SEC rules, the Company is required to provide certain information concerning compensation provided to the Company's Chief Executive Officer and the Named Executive Officers. The disclosure requirements for these individuals include the use of tables and a report of the committee responsible for compensation decisions for these individuals, explaining the rationale and considerations that led to those compensation decisions. Therefore, the Compensation Committee of the Board of Directors has prepared the following report for inclusion in this Proxy Statement: The Compensation Committee of the Board of Directors ("Compensation Committee") is composed of Mr. Stollenwerk, Mr. Mattson, and Mr. Stein. The Compensation Committee is responsible for the review of all employee salaries in excess of $75,000 or who report directly to the Company's Chief Executive Officer. The Compensation Committee also reviews all bonus, commission and stock option programs. The Compensation Committee meets as a group each spring and reviews its report with the full Board prior to the end of the fiscal year. This system enables management to plan the following year more appropriately. The Company employs a compensation program linked to company-wide performance and individual achievement. All executive officers are reviewed twice each year. Raises in base salaries are made in July when necessary or when promotions are announced. In addition, the Company has a Flexible Incentive Plan, an Employee Stock Ownership Plan and Trust, a 401(k) Plan, and a Profit Sharing Plan. The Company also has a cafeteria benefits plan to provide flexibility to employees to choose their own health care and associated benefits package from an array of offerings. The Company shares the cost of medical insurance with its employees. 11

The Company's executive officers are paid base salaries commensurate with their responsibilities, after comparison with base salaries of executive officers of other light assembly or manufacturing companies taken from data in an annual national survey. Executive officers are also eligible for annual bonuses based upon individual performance and overall Company performance and profitability. Factors relevant to determining such bonuses include attainment of corporate revenue and earnings goals and the development of new accounts. The Company's Chairman is eligible to receive a bonus calculated as a percentage of the Company's earnings before interest and taxes. The Company's Vice President-Sales is entitled to receive a bonus based upon increases in sales over the prior year, and a bonus for obtaining new accounts from a predetermined list of potential new accounts and for adding new product lines to current accounts. The Company's Vice President - Europe is entitled to receive a bonus based upon the Company's sales in export markets. The Compensation Committee annually reviews and determines the compensation of Michael J. Koss, President and Chief Executive Officer. Michael J. Koss' salary is based on his experience, responsibilities, historical salary levels for himself and other executive officers of the Company, and the salaries of Chief Executive Officers of other light assembly or manufacturing companies. Michael J. Koss is also eligible to receive a bonus calculated as a percentage of the Company's earnings before interest and taxes. He also participates in the Company's Flexible Incentive Stock Option Plan. COMPENSATION COMMITTEE MARTIN STEIN LAWRENCE S. MATTSON JOHN J. STOLLENWERK THE REPORT OF THE COMPENSATION 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. 12

STOCK PRICE PERFORMANCE INFORMATION The graph and table below set forth information comparing the yearly cumulative total return on the Company's Common Stock over the past five years with the yearly cumulative total return on (i) stocks included in The Nasdaq Stock Market (US Companies) Index, and (ii) a group of peer companies ("Peer Group"). The Peer Group consists of Boston Acoustics, Inc., Digital Video Systems, Inc., and Phoenix Gold International, Inc., companies which the Company believes are similar in terms of market capitalization and business lines. The Peer Group used last year also included Sensory Science Corporation, which is not included in this year's Peer Group as a result of its acquisition by another company. For purposes of the graph and table, it is assumed that on July 1, 1998, $100 was invested in the stock of each of (i) the Company, (ii) the companies on The Nasdaq Stock Market (US Companies) Index, and (iii) the companies in the Peer Group (the return for the investment in the stock of each company in the Peer Group is weighted according to the stock market capitalization of each company as adjusted at the beginning of each fiscal year indicated on the table). The graph and table also assume that all dividends paid were reinvested in the stock of the issuing companies.

RELATED TRANSACTIONS BUILDING LEASE. The Company leases its main plant and offices in Milwaukee, Wisconsin from its Chairman, John C. Koss. On May 28, 2003, the lease was renewed for a period of five years, and is being accounted for as an operating lease. The lease extension maintained the rent at a fixed rate of $380,000 per year. At anytime during this period the Company has the option to renew the lease for an additional five years for the period commencing July 1, 2008 and ending June 30, 2013 under the same terms and conditions. The Company believes that the lease is on terms no less favorable to the Company than those that could be obtained from an independent party. 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, because the Company believes that its stock is undervalued in the current market and that such repurchases enhance the value to stockholders. Consistent with this policy, the Company repurchased 67,500 shares during the fiscal year ended June 30, 2003. The Company believes that purchases of Common Stock enhance stockholder value and will continue from time to time to engage in such transactions either on the open market or in private transactions. The Company has an agreement with its Chairman, John C. Koss, to repurchase Common 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 that 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 June 30, 2003, $1,490,000 has been classified as a Contingently Redeemable Equity Interest on the Company's financial statements reflecting the estimated obligation in the event of execution of the agreement. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires the Company's directors and executive officers, and persons who own more than 10% of a registered class of the Company's equity securities, to file with the SEC and with The Nasdaq Stock Market reports of ownership and changes in ownership of Common Stock and other equity securities of the Company. Officers, directors and greater than 10% shareholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file. Based solely on review of such reports furnished to the Company or representations that no other reports were required, the Company believes that, during the 2003 fiscal year, all filing requirements applicable to its officers, directors, and greater than 10% beneficial owners were complied with. 14

ITEM 2. RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITOR The Board of Directors, following the recommendation of its Audit Committee, has retained PricewaterhouseCoopers as independent accountants to audit the consolidated financial statements of the Company and its subsidiaries for the fiscal year ending June 30, 2004. PricewaterhouseCoopers has served the Company as its independent auditors since September 1992. Representatives of PricewaterhouseCoopers are expected to be present at the Meeting, and will have the opportunity to make a statement if they desire to do so. The PricewaterhouseCoopers representatives are expected to be available to respond to appropriate questions at the Meeting. AUDIT FEES. The aggregate fees billed by PricewaterhouseCoopers for professional services rendered for the audit of the Company's annual consolidated financial statements and the reviews of the consolidated financial statements included in the Company's quarterly 10-Q filings, for the fiscal year ended June 30, 2003, were $90,000. FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES. The aggregate fees billed by PricewaterhouseCoopers for financial information systems design and implementation services for the fiscal year ended June 30, 2003, were $0. ALL OTHER FEES. The aggregate fees billed by PricewaterhouseCoopers for professional services rendered, which primarily related to income tax compliance, tax consulting and other services for the fiscal year ended June 30, 2003, were $72,300. The Audit Committee has considered whether the performance of the services described above under the caption "All Other Fees" is compatible with maintaining PricewaterhouseCoopers' independence. Although this appointment 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) is not received, the Board will reconsider the appointment. Unless otherwise directed, the proxy will be voted in favor of the ratification of such appointment. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" RATIFICATION OF PRICEWATERHOUSECOOPERS AS INDEPENDENT ACCOUNTANTS FOR THE YEAR ENDING JUNE 30, 2004. 15

ITEM 3. TRANSACTION OF OTHER BUSINESS The Board of Directors of the Company is not aware of any other matters that may come before the meeting.
