Harman International, the wholly owned subsidiary of Samsung Electronics, has completed its acquisition of Sound United, the former consumer audio business of Masimo Corporation.

The deal brings a number of iconic audio brands under Harman’s umbrella, including Bowers & Wilkins, Denon, Marantz, Definitive Technology, Polk Audio, HEOS, Classé, and Boston Acoustics. The move massively expands Harman’s presence across home audio, Hi-Fi components, AV receivers, headphones and car audio.

This acquisition marks a major step for Harman, which already has a strong reputation in consumer and professional audio. By combining Sound United’s portfolio with its own, the company says it can now deliver one of the most comprehensive audio ranges in the industry.

Dave Rogers, President of Harman’s Lifestyle Division, said: “Harman’s vision is to create experiences that enrich people’s lives through exceptional audio experiences. Sound United’s impressive roster of brands is rooted in a deep passion for sound, innovation, and commitment to quality that aligns with Harman’s own values. This transaction unlocks meaningful growth opportunities for everyone. It bolsters Harman’s strategy to build on its unparalleled success story and scale to unprecedented heights as an audio leader.”

As part of the deal, Sound United will operate as a standalone Strategic Business Unit within Harman’s Lifestyle Division. This structure, the company says, will ensure that each brand maintains its heritage, expertise and loyal customer base while gaining from Harman’s global reach and resources.
