EXHIBIT 31.1

                                KOSS CORPORATION

                                 CERTIFICATION*

I, Michael J. Koss, certify that:

1.       I have reviewed this quarterly report on Form 10-Q of Koss Corporation;

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.       The registrant's other certifying officers and I are responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
         registrant and we 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 and presented in this quarterly report our
             conclusions about the effectiveness of the disclosure controls and
             procedures, as of the end of the period covered by this report
             based on such evaluation;

         c)  Disclosed in this report any change in the registrant's internal
             control over financial reporting that occurred during the
             registrant's most recent fiscal quarter (the registrant's fourth
             fiscal quarter in the case of an annual report) that has materially
             affected, or is reasonably likely to materially affect, the
             registrant's internal control over financial reporting; and

5.       The registrant's other certifying officers and I have disclosed, based
         on our most recent evaluation of internal control over financial
         reporting to the registrant's auditors and the audit committee of
         registrant's board of directors (or persons performing the equivalent
         function):

         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

         b)  Any fraud, whether or not material, that involves management or
             other employees who have a significant role in the registrant's
             internal control over financial reporting.
