Sonos announced a round of layoffs earlier this month, and now a turbulent March continues. The company has confirmed that chief product officer Marc Whitten has departed the company after a two-year stint. During his time at Sonos, Whitten oversaw two of the company's most important product launches in its history: the excellent new Play:5 speaker and the speaker-tuning TruePlay software. A company spokesperson gave us the following statement: "Marc Whitten has decided to leave Sonos, and his last day was Friday, March 25. We thank Marc for this hard work and meaningful contributions over the past two years."
