When the Music Died: How Sonos Killed Its Own App and Lost Everything

Sonos shipped an unfinished app that broke thousands of speakers, wiped $500M in value, and took down the CEO. Brian Crowley and Eve Eden investigate one of the biggest UX failures ever.

You spend thousands on premium speakers. They work beautifully for years. Then one update kills everything — your alarms vanish, your speakers disconnect, and you can't even adjust the volume.

In this episode, hosts Brian Crowley and Eve Eden investigate how Sonos shipped an unfinished app rebuild in May 2024 that triggered 30,000+ complaints, wiped nearly $500M in market value, cost 100 employees their jobs, and ultimately took down both the CEO and Chief Product Officer.

We break down why leadership ignored internal warnings, how blind users were completely locked out, and what every product team can learn from one of the biggest UX failures in recent memory.

By the numbers: $500M+ wiped from market value. 30,000+ customer complaints. 16% revenue decline in Q4 2024. ~100 employees laid off. CEO and CPO both ousted.
