- Koss Corporation (NASDAQ: KOSS) designs, manufactures, and sells high-fidelity stereo headphones, wireless headphones, communications headsets, speakerphones, active noise-canceling headphones, computer headsets, telecommunications headsets, and related audio accessories including detachable cables, adapters, and ear cushions; the company offers iconic product lines such as Porta Pro (including wireless and limited-edition variants), Pro/4AA, KPH30 (wired and wireless), KPH40 Utility, Sporta Pro, earclip models like KSC35 and KSC75, in-ear monitors such as The Plug and KEB25i, studio and professional headphones like Pro4S, and gaming/work-from-home headsets including CS300 USB. Koss Corporation targets consumer audiophiles, music enthusiasts, gamers, professionals, education markets, and direct-to-consumer segments through its e-commerce platform, with products distributed via retailers, e-tailers, and international channels. Founded in 1953 by John C. Koss in Milwaukee, Wisconsin, where it maintains its headquarters at 4129 North Port Washington Avenue, the company pioneered the world's first high-fidelity stereophone (SP/3) in 1958 and went public in 1967, operating primarily in the consumer electronics industry with a focus on personal audio solutions and global sales. In recent developments, Koss Corporation reported strong financial performance in fiscal Q1 2026 with net sales up 27.1% to $4.07 million driven by major education sector sales and 22.5% direct-to-consumer growth, alongside improved gross margins of 40.0% despite China tariffs; full fiscal 2025 sales reached $12.62 million (up 2.9% year-over-year) with DTC representing nearly 25% of revenue and export markets growing 49% in Q4. The company promoted Michael J. Koss, Jr. to Executive Vice President in October 2025, recognizing his leadership in new product development (including KPH30 Wireless), DTC expansion, logistics, and intellectual property enforcement; earlier in 2025, Koss launched Porta Pro Wireless 2.0 and KPH30 Wireless as part of its Utility Series refresh. Koss continues to pursue patent enforcement actions stemming from prior 2020 lawsuits against Apple (settled in 2022) and others for wireless headphone technology infringement, while navigating tariff impacts and institutional investor adjustments in Q2 2025.
