Exhibit 99.1

NOTICE OF PROPOSED SETTLEMENT OF DERIVATIVE LITIGATION
AND HEARING

TO: ANY PERSON WHO OWNED KOSS CORPORATION COMMON STOCK AS OF JUNE 24, 2011 (“KOSS SHAREHOLDER”)

PLEASE READ THIS NOTICE CAREFULLY

THIS NOTICE RELATES TO THE PENDENCY AND PROPOSED
SETTLEMENT OF THIS SHAREHOLDER DERIVATIVE LITIGATION

YOU ARE HEREBY NOTIFIED that a proposed settlement (the “Settlement”) has been reached between Plaintiffs, on behalf of Koss Corporation (“Koss” or the “Company”), and the Koss Directors (defined below).

A hearing (the “Settlement Hearing”) will be held on August 11, 2011, at 1:30 p.m. in Courtroom 403 of the Milwaukee County Courthouse, 901 North 9th Street, Milwaukee, Wisconsin to determine: (i) whether the Settlement of the Derivative Litigation on the terms and conditions provided for in the Stipulation of Settlement dated as of June 7, 2011 (the “Stipulation”) (including the provision for the payment of $1,300,000 to Plaintiffs’ counsel for fees and expenses), is fair, reasonable and adequate to Koss Shareholders and to Koss and should be approved by the Court; and (ii) whether a Judgment as provided in the Stipulation should be entered dismissing the Derivative Litigation.

I.              BACKGROUND OF THE LITIGATION

On or about February 18, 2010, Plaintiff James Mentkowski filed Case No. 10-CV-002290 in the Circuit Court of Milwaukee County, Wisconsin, on behalf of nominal defendant Koss Corporation against Defendants Michael J. Koss, John C. Koss, John J. Stollenwerk, Thomas L. Doerr, Theodore H. Nixon, and Lawrence S. Mattson (collectively, the “Koss Directors”) and Sujata Sachdeva. On or about February 16, 2010, Plaintiff Myriam Ruiz filed Case No. 10-CV-002422 in the Circuit Court of Milwaukee County,

1

Wisconsin, against nominal defendant Koss Corporation, the Koss Directors, Sujata Sachdeva and Grant Thornton LLP (“Grant Thornton”). On April 28, 2010, the Mentkowski (Case No. 10-CV-002290) and Ruiz (Case No. 10-CV-002422) actions were consolidated (the “Action”), and the Court appointed the law firms of Robbins Geller Rudman & Dowd and Robbins Umeda as co-lead counsel in the Action.

The Action arises out of defendant Sachdeva’s embezzlement from Koss. Plaintiffs filed their Verified Consolidated Shareholder Derivative Complaint (“Consolidated Complaint”) on July 21, 2010, alleging breach of fiduciary duties and unjust enrichment against the Koss Directors, waste of corporate assets and unjust enrichment against Sachdeva, and unjust enrichment, negligence, accounting malpractice and aiding and abetting breaches of fiduciary duty against Grant Thornton.

The Koss Directors and Koss (the “Koss Defendants”) moved to dismiss the Consolidated Complaint on the ground that Plaintiffs failed to make a pre-suit demand on the Koss Board of Directors prior to filing suit or to allege particularized facts establishing that such demand should be excused. On November 29, 2010, the Court denied the requested relief. Following the denial of the demand futility motion, on January 12, 2011, nominal defendant Koss filed a motion to be re-aligned as plaintiff in the claims against Grant Thornton. On February 28, 2011, the Court denied the requested relief.

Beginning in December 2010, the Plaintiffs on behalf of themselves, Koss and its shareholders and the Koss Defendants (collectively, the “Settling Parties”) engaged in substantive settlement negotiations. Counsel for the Settling Parties held numerous discussions thereafter. In connection with those discussions, Koss produced to Plaintiffs

2

non-public documents, which Plaintiffs reviewed as the Settling Parties continued with their settlement negotiations.

During the course of the Action, Plaintiffs propounded extensive discovery on defendants (and third parties), including document requests and interrogatories. Plaintiffs also noticed depositions. As a result of Plaintiffs’ discovery efforts, the Koss Directors and Koss produced hundreds of thousands of pages of responsive, non-public documents to Plaintiffs and to the Koss Defendants. Grant Thornton also produced over 165,000 pages of non-public documents to Plaintiffs. Thus, the Settling Parties, and their respective counsel, have had the opportunity to comprehensively evaluate their respective positions regarding the merits of the Action and to assess their respective prospects for success on the claims asserted therein.

On April 26, 2011, Plaintiffs’ counsel, as well as counsel for the Koss Directors, Koss, and counsel for the Koss Defendants’ insurance carrier, participated in a formal in-person mediation (the “Mediation”) before the Honorable Howard B. Wiener (Ret.), a former Associate Justice of the California Court of Appeal. After several months of arms-length negotiations, including the April 26, 2011 mediation, the parties reached an agreement in principle to settle the Action.

Plaintiffs, Koss and the Koss Directors agree that it is in the best interests of Koss and its shareholders to settle the Action on the terms described below, and that the Settlement, taken as a whole, including payment of attorneys’ fees and expenses of $1.3 million to Plaintiffs’ counsel, is fair and reasonable and in the best interests of Koss and its shareholders.

II.            CLAIMS OF PLAINTIFFS AND BENEFITS OF SETTLEMENT

The Plaintiffs believe that the claims asserted in the Action have merit, which the Koss Directors deny. However, Plaintiffs recognize and acknowledge the expense and length of continued proceedings necessary to prosecute the Action against the Koss Directors through trial and appeal. Plaintiffs also have taken into account the uncertain outcome and the risk of any litigation, especially in complex actions such as the Action, as well as the difficulties and delays inherent in such litigation. Plaintiffs also are mindful of the inherent problems of proof of, and possible defenses to, the claims asserted in the Action. Plaintiffs believe that the Settlement set forth in the Stipulation addresses many of the issues raised in the Action and confers substantial benefits upon, and is in the best interests of, Koss and its shareholders.

In this regard, with respect to the Released Claims, the Settling Parties stipulate and agree that, upon the Effective Date, Plaintiffs and Koss shall expressly waive, and each Koss shareholder shall be deemed to have and by operation of the Judgment shall have expressly waived, the provisions, rights and benefits conferred by Section 1542 of the California Civil Code (“Section 1542”), and by any law of any state or territory of the United States or any other state, sovereign or jurisdiction, or any principle of common law that is similar, comparable or equivalent to Section 1542, which provides:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

The parties have reached agreement regarding Corporation Governance Measures, as set forth in ¶ 2.1 of the Stipulation. In general, and among other things, the Corporate Governance Measures create, modify, or formalize policies and practices with respect to: the structure of, membership on, or independence of, Koss’ Board of Directors; shareholder meetings, reimbursement of excess bonus/incentive based on compensation if restatement occurs, external auditor and Koss Audit Committee function; accounting and internal audit functions; and Koss’ whistleblower and complaint programs. The Koss Directors deny that the Corporate Governance Measures are or were required by any statute, rule, regulation, duty or practice. In connection with the Settlement, except as otherwise specified in the Stipulation, the Company shall, within thirty (30) days of the Effective Date, adopt the Corporate Governance Measures. The Settling Parties acknowledge that the pendency and prosecution of the Action were substantial factors in the decision to implement and/or maintain the Corporate Governance Measures, which provide a substantial benefit to the Company.

10

b.             Additional Settlement Terms

As set forth in ¶ 3 of the Stipulation (“Additional Settlement Terms”), the Koss Directors have agreed to take certain additional actions, including causing their insurer to pay Koss $850,000 as further consideration to Koss for the Settlement set forth in the Stipulation and an agreement that Koss and plaintiffs’ counsel will jointly prosecute any claims against Grant Thornton that have been or could be asserted by or on behalf of Koss in the Action, including, without limitation, Koss Corporation v. Sachdeva, No. 2010-L-007342, filed in the Circuit Court of Cook County, Illinois on June 24, 2010.

c.             Attorneys’ Fees & Expenses

Subject to Court approval, on behalf of and for the benefit of the Koss Defendants, the Company will cause its insurance carrier to pay $1,300,000 as the Court may approve in attorneys’ fees and expenses awarded by the Court (the “Fee and Expense Award”), to Plaintiffs’ Counsel on or before ten (10) business days after entry of the Fee and Expense Award; provided that Plaintiffs’ Counsel shall seek an award of attorneys’ fees and expenses in the aggregate amount of $1,300,000, and the Company shall not pay or cause to be paid any award in excess of that amount. Plaintiffs and Plaintiffs’ counsel have agreed that they will not request that the Court approve payment of attorneys’ fees and expenses, or reimbursement or compensation for any other costs or expenses, in excess of $1,300,000, both in the Court and on any appeal. The Koss Defendants have agreed not to oppose Plaintiffs’ counsel’s request for such approval in an amount of $1,300,000, both in the Court and on any appeal. The Settling Parties negotiated the provisions related to the fee and expense award after they agreed to other substantive terms of the Stipulation.

11

IV.           RELEASES

Plaintiffs for themselves, and on behalf of Koss Corporation, intend to give a “Pierringer” release pursuant to, and governed by, the substantive law of Wisconsin. Without limiting the generality of the preceding sentence, the intent of the parties to the Stipulation is that the release shall be construed in accordance with the doctrines set forth in the case of Pierringer v. Hoger, 21 Wis.2d 182, 124 N.W.2d 106 (1963).

For and in consideration of the corporate governance measures set forth in ¶2.1 of the Stipulation and the additional settlement undertakings set forth in ¶3.3 and ¶3.4 of the Stipulation, upon the Effective Date, the Plaintiffs (acting on their own behalf and derivatively on behalf of Koss) and Koss shall have, and each Koss shareholder shall be deemed to have, and by operation of the Judgment shall have, fully, finally, and forever released, relinquished and discharged the Released Claims, including Unknown Claims, against the Released Persons. Nothing herein shall in any way impair or restrict the rights of any of the Settling Parties to enforce the terms of the Stipulation.

Plaintiffs have agreed, for themselves and on behalf of Koss, that in making this release, they have not relied on representations or statements made by the Koss Defendants hereby released or anyone representing them and are relying on their own judgment, belief and knowledge as to all phases or aspects of Plaintiffs’ claims.

This is a qualified, conditional release intended to release only the Released Persons. Anything to the contrary in the Stipulation notwithstanding, nothing in the Stipulation is intended to release any other parties or nonparties. Plaintiffs do not intend to release for themselves and/or for Koss anything other than that portion of the injuries, losses or other

12

damages resulting to Koss, Plaintiffs and/or their property which are attributable to the Released Persons and which arise out of or relate to Plaintiffs’ allegations on behalf of Koss set forth in the Consolidated Complaint. Koss expressly reserves, and Plaintiffs expressly reserve on behalf of Koss, the balance of Koss’ whole claim of, or any other claims of, whatever kind or nature not released which Koss may have or hereafter have against any other person or persons arising out of the allegations set forth in the Consolidated Complaint, including but not limited to Grant Thornton, Defendant Sachdeva, American Express Company, American Express Travel Related Services Company, Inc., AMEX Card Services Company, Decision Science, Pamela Hopkins, and Park Bank, Bank of America Corp., Bank of America Capital Corp., Bana Holding Corp., Harris Bankcorp, and/or any other parties not referenced or identified herein.

As further consideration for the Settlement, Plaintiffs have agreed, for themselves and on behalf of Koss, and Koss has agreed, that Koss may and shall indemnify the Koss Defendants and save them harmless from any claims for contribution or indemnity made by others so adjudged jointly liable with any or all of the Koss Directors, but only to the extent such claims for contribution or indemnity are established and awarded by final judgment after all appeals. Plaintiffs have further agreed, on behalf themselves and Koss, that Koss will satisfy any judgment which may be rendered in favor of Plaintiffs or Koss, satisfying such fraction, portion, or percentage of the judgment as the causal negligence or fault of the Released Persons is determined to be of all causal negligence or fault of all adjudged tortfeasors.

13

Upon the Effective Date, each of the Released Persons shall be deemed to have, and by operation of the Judgment shall have, fully, finally, and forever released, relinquished and discharged each and all of the Plaintiffs and Plaintiffs’ Counsel from all claims (including Unknown Claims) arising out of, relating to, or in connection with, the institution, prosecution, assertion, settlement or resolution of the Action or the Released Claims. Nothing in the Stipulation shall in any way impair or restrict the rights of the Settling Parties to enforce the terms of the Stipulation.
