Audio brand Harman International has agreed to acquire the audio brands Bowers & Wilkins, Denon, Polk and Marantz from Masimo.

Samsung Electronics said on Wednesday its unit Harman International signed a deal to acquire U.S. firm Masimo's audio business for $350 million.

Now, in a move that many suspected might come sooner, Masimo is unwinding that decision—announcing the sale of Sound United to HARMAN International (a Samsung subsidiary) for $350 million in cash.
