Re:  Registration Statement on Form S-8

Gentlemen:

        We have acted as counsel for Koss Corporation, a Delaware corporation
(the "Company"), in connection with the Company's registration of its offering
to its key executive employees of up to 348,128 additional shares of its $.01
par value common stock (the "Common Stock") pursuant to the Koss Corporation
1990 Flexible Incentive Plan(the "Plan").

        In such capacity, we have examined, among other documents, the
Certificate of Incorporation of the Company, as amended, the Bylaws of the
Company, as amended, and the Registration Statement on Form S-8 to be filed by
the Company with the Securities and Exchange Commission on or shortly after the
date of this letter covering the offering of the Company's Common Stock
pursuant to the Plan.  Based on the foregoing and such additional investigation
as we have deemed necessary, it is our opinion that the shares of Common Stock
to be offered under the Plan have been legally and validly authorized under the
Certificate of Incorporation of the Company and the laws of the State of
Delaware.  When issued and
 paid for in accordance with the description set
forth in the Registration Statement and the Plan, the Common Stock will be
legally issued, fully-paid and non assessable, except as set forth in Wisconsin
Statutes Section 180.0622(2)(b) as interpreted.

        We have prepared this letter as attorneys admitted to practice law in
the state of Wisconsin and do not purport to be experts on Delaware law, nor
have we obtained an opinion of local counsel in the state of Delaware.  The
opinion expressed herein is based upon an examination of (a) the statutes of
the state of Delaware as reported in standard compilations available to us, (b)
the Certificate of Incorporation of the Company, as amended, (c) the Bylaws of
the Company, as amended, (d) the Registration Statement on Form S-8, and (e)
our investigation.
