I love my Powerbeats for that exact reason.
I used to use Airpods for sleep, and they worked - but they broke in an absolutely ridiculous period of time (first pair in 3 months, second pair just slightly over 9 months later - just late enough they wouldn’t do anything about it under warranty), so I’m not keen to re-purchase.
I might look into an Airpods knockoff though, since pristine audio and microphone quality aren’t my top priorities here.
