                             KOSS SALES UP SLIGHTLY
                       PROFITS SLIP ON DISTRIBUTION SHIFTS

OCTOBER 6, 2003 -- MILWAUKEE, WISCONSIN: Koss Corporation (NASDAQ SYMBOL: KOSS),
the U.S. based high fidelity stereophone leader, has announced the results of
its first quarter for the period ending September 30, 2003. Sales for the first
quarter increased to $9,164,691 compared to $8,954,978 for the same period one
year ago. Net income for the period declined to $1,020,504 from $1,100,778 one
year ago. First quarter diluted earnings per share were $0.26 compared with
$0.29 one year ago.

"Our acquisition of Addax, now renamed BiAudio, did help to pull sales ahead of
the prior year," Michael J. Koss, President and CEO, told employees at a
quarterly profit sharing meeting. "The decline of approximately $80,000 in net
income can be attributed to expenses relating to shifts in servicing our
distribution channels, particularly Canada, as well as a slight efficiency sag
relating to the accelerated integration of the new BiAudio operation."

Michael Koss went on to explain that the Company had changed its method of
servicing the Canadian market during the second half of the prior year and the
expenses for outbound freight and sales commissions have been running slightly
higher than expected and that the BiAudio operation had been absorbed from
Chicago into the Milwaukee based facility.

"We have had several promotional programs for the holiday selling season in this
quarter and the increase in expenses offered to these accounts this year were
not part of last years results," Koss said. "The fact that sales commission
expenses have increased could indicate a stronger improvement in a broader
segment of accounts rather than an improvement in the accounts managed directly
by the Koss internal sales force."

Koss went on to say that the retail based portion of the Company's business
continued to be spotty, but was beginning to show some signs of recovery and
that export sales, particularly to Europe, were up sharply, 83%.

"We are looking forward to the holiday selling season with confidence for the
first time in two years," Koss said, as he displayed a new package featuring
Santa Claus wearing Koss stereophones. "We're hoping that our commitment in
promotional dollars this quarter will 'Knock the Stockings Off' gift giving
music lovers this holiday season."

Koss will pay a dividend of $0.13 cents per share on October 15, 2003, to
shareholders of record September 30, 2003.
