Masimo Corp. has entered into a definitive agreement to sell its Sound United consumer audio division to HARMAN International for $350 million in cash, the company announced Tuesday.

The sale, expected to close by the end of 2025, is part of Masimo’s broader strategy to focus on its core professional healthcare business. HARMAN International is a wholly owned subsidiary of Samsung Electronics Co., Ltd.

“Finding the right home for this business has been a stated priority of the new Board from day one,” said Quentin Koffey, vice chairman of Masimo’s board. “This transaction represents an important milestone as we continue to position the company to achieve our goals of accelerating revenue growth while delivering disciplined margins.”

Sound United, Masimo’s consumer audio unit, includes brands such as Bowers & Wilkins, Denon, Marantz and Polk Audio. These will join HARMAN’s portfolio of audio brands, which includes JBL, Harman Kardon and AKG.

“This acquisition represents a strategic step forward in the expansion of HARMAN’s core audio business and footprint across key product categories,” said Dave Rogers, president of HARMAN’s Lifestyle division. “It complements our existing strengths and opens new avenues for growth.”

“Since I took over as CEO, a key objective has been refocusing our business to ensure we are allocating time and resources to areas of unmet clinical need,” said Masimo CEO Katie Szyman. “This transaction aligns with these objectives.”

The transaction is subject to customary closing conditions and regulatory approvals. Centerview Partners LLC and Morgan Stanley & Co. LLC served as financial advisors to Masimo. Sullivan & Cromwell LLP served as legal advisor.
