For Immediate Release Contact: acquisitions@koss.com www.kosscorporation.com Koss Corporation Drives Expansion Initiative with New Hire (Milwaukee, Wisconsin) March 16, 2026 - Koss Corporation (NASDAQ: KOSS) (the “Company”), the U.S. based high-fidelity headphone company, has announced the addition of Megan Brobson as Director of Acquisitions and Corporate Development. “We intend to use the strength of our balance sheet to add solid, well-managed companies to our portfolio,” Michael J. Koss, Chairman and CEO said today. “Our first step in this process is the addition of new talent.” Ms. Brobson brings with her over a decade of experience in private equity and client finance roles, most recently at a lower middle market private equity firm. There she played an active role across the firm’s investment lifecycle activities including cultivating relationships with business owners and intermediaries, identifying and executing new investment opportunities, and working alongside management teams to develop and execute value creation strategies. She will remain an active member of the community with her board positions with Midwest Business Brokers and Intermediaries (MBBI), Marquette University Business Alumni Association and United Way of Greater Milwaukee & Waukesha County Investment Committee. “Megan brings the optimal skill set and fresh market experience for this new initiative,” Michael J. Koss Jr., Executive Vice President said. “We are pleased and excited to have her join the team.” Michael Koss Jr. went on to explain that the success of the Company’s intellectual property enforcement campaign coupled with prudential cash management has created the perfect opportunity to diversify. “Over the last 15 years we have patiently re-sized and re-branded Koss Stereophones back to our founding principles, with a focus on incredible sound and an amazing customer experience. We are growing the brand in the channels we strategically chose, which has enabled us to begin a new phase outside the headphone space.” “To be clear, we are not seeking any strategic or synergistic partnerships in our existing consumer electronics market space,” Koss Jr. continued. “We seek diversification. We are interested in upstanding companies that we will acquire, grow, and hold as a part of Koss Corporation for the long term, preferably forever.” The Company expects to pursue acquisition targets in the $2-4 million EBITDA range. “Seventy-three years ago, my father, John C. Koss, started our company to rent televisions to hospital patients.” Michael J. Koss, Chairman & CEO concluded. “We’ve evolved several times since and are best known for innovations with Koss Stereo Headphones. Today we’re announcing a new phase in our storied history, led by a new generation represented by Michael Koss Jr. and Megan Brobson with a concise strategic initiative focused on acquisitions.” Visit www.kosscorporation.com to learn more.

What Are Koss Hybrid Headphones? Designed for Longevity. Not Obsolescence. Koss Hybrid Headphones are designed to move effortlessly between wireless freedom and wired fidelity. On the surface they deliver everything modern listening demands like Bluetooth convenience, lightweight comfort, and the unmistakable Sound of Koss®. But beneath that simplicity, is something more enduring, they’re about future-proofing. Ports change. Standards evolve. Bluetooth versions come and go. Analog audio remains universal. By supporting both wireless and wired listening, Koss Hybrid Headphones resist planned obsolescence and extend the life of products that were designed to last in the first place. This is sustainability through design, not trend. How Do Koss Hybrid Headphones Work? One headphone. Two signal paths. Zero compromise. Headphones like Porta Pro® Wireless and KPH30 Wireless feature Analog Audio Pass Through via their USB-C charging port. Along with the Koss KUSB-50 Analog Audio Pass Through Cord, these same headphones transform. Plug them in, bypass Bluetooth compression, and experience pure, lossless analog audio direct from your source to the drivers. The result is immediacy, depth, and detail exactly as the music was intended to be heard. No Latency. No compression. No compromises. Hybrid Matters Wireless for Life. Wired for Truth. Bluetooth is perfect for movement, multitasking, and everyday listening. But even the best wireless codecs rely on compression and lossy audio. Wired audio doesn’t. When connected via the KUSB-50 Analog Audio Pass Through cord, you unlock the full resolution of your music. No latency
