Many of you probably already have something similar to this, but I just bought one recently... It's a waterproof bluetooth speaker for music in the shower. There are some cheaper ones that are probably solid as well, but this one is actually waterproof and not just water resistant. I have a Jawbone Jambox as well and it may just be the acoustics in the bathroom but I swear this thing is just as loud and clear as the Jambox which was $100 and isn't waterproof. This is $20 well spent. Highly recommend.
