Seems pointless and inconvenient for me as they usually seem to be poor quality, and can you really listen to music in the shower, and are you showering long enough to benefit from it?
Or do you own one and use for a different purpose, like swimming or Kayaking?
Since my phone is water resistant, I put a magnetic mount in the shower to listen to music, podcasts, and the occasional Teams meeting if I’m running late.
A Teams meeting!? I wish I was as brave as you. I’m not even brave enough to poop while listening to a Teams call, much less showering. I’m terrified they’ll call me out and I’ll either have to unmute at the worst possible moment or stay muted and have my boss assume I’m not paying attention.
If I showered during a meeting I would be paranoid about somehow magically turning on my camera.
