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?
Nothing wakes me up better than singing in the shower. So…hell yeah I have a Bluetooth speaker in my shower. I also like podcasts some days.
It’s a cheap Chinese nonsense brand 20W waterproof portable speaker, sound quality is remarkable considering it was like $20, and it has served me well for over five years.
