Dear Stockholder:

We are very pleased to announce results for the fiscal year ending June 30,
2001.

Sales for the fourth quarter ending June 30, 2001 were up 5% to $10,186,107
compared with $9,745,408 for the same period one year ago. Income from
operations for the quarter increased 23% and reached $2,521,133 compared with
$2,051,156 for the fourth quarter of 2000. Net income increased 11% to
$1,692,877 compared with $1,527,987 for the same three month period last year.
Fourth quarter diluted earnings per share increased by 31% to $0.81 compared
with $0.62 for the fourth quarter of fiscal year 2000.

Year-to-date sales for the 12 months ending June 30, 2001 increased by 9% to
$38,609,335 compared with $35,401,533 for the fiscal year 2000. Income from
operations for the 12 months increased by 23% to $8,126,089 from $6,611,003.
Year-to-date income for the 12 months increased by 15% reaching a company high
of $5,687,521 compared with $4,953,461 for the 12 months ending June 30, 2000.
Diluted earnings per share were $2.56, an increase of 35% over the previous
fiscal year record of $1.90.

The final quarter for the fiscal year was exceptional. Throughout the year we
had been anticipating a lower fourth quarter compared with 2000 and instead we
are pleased to report a solid increase in sales and earnings. This is simply our
best year of stereophone sales in the history of the Company and has produced a
record in terms of our profitability. The Company had been most successful
through the year in its growth of the base stereophone business at retail,
despite setbacks in the OEM and automotive segments of the business.

Our Sales team was consistently challenged to perform this year by meeting and
exceeding progress we made last year in areas outside our consumer retail
business. The Company's ability to make up for slumps in the OEM sectors through
increases in our sales to the retail channel helped post solid gains for the
year and led us to new records in terms of our profitability and earnings.

In addition, income from operations had shown more solid and consistent growth
than net income based upon inconsistencies in royalty income through the year.
Renewal of the license agreement with Orient Power has now been extended for an
additional 12 months.

Koss remains committed to its core Stereophone business and improvements in new
product development and placement in both current and new accounts will continue
to positively impact fiscal year 2002. The Company will continue to use cash to
buy its undervalued shares from the market.

We are also pleased to announce that following the First Quarter of this fiscal
year, the Company will pay a $0.25 dividend to shareholders of record on
September 30, 2001. This is the first time Koss has paid a dividend to
shareholders since 1984. While the Company anticipates the ability to pay a
quarterly dividend in the future, investors should be cautious not to expect
this to automatically continue or to see any annual increase in the quarterly
rates in the foreseeable future.

We would like to take this opportunity to thank our customers, suppliers,
stockholders as well as the entire Koss team for their dedication to the current
and future success of Koss Corporation.

Sincerely,

John C. Koss               Michael J. Koss
Chairman                   President and CEO
