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?
I know grammar is hard, but OP is clearly saying that using a Bluetooth speaker in the bathroom seems pointless, not music listening in general.
Maybe at least be correct if you’re going to be a dick.
He’s saying Bluetooth speakers seem pointless because the music seems pointless.
Music listening in general ≠ listening to music in the shower.
