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?
Yea I start playing music from my phone as soon as I’m awake enough to figure out what I want to listen to. It helps me fully wake up a bit quicker. After shower, etc I change it to cast to my living room speaker system, or back to my phone (+headphones) if I’m going out.
