Review on Waterproof Shower Speaker: IPX7 Certified Bluetooth 5.0 Speaker with HD Sound, FM Radio - Perfect for Shower, Pool, Bathroom, Trekking & Outdoors by Jarrett Love

Very good speaker for the shower. It has a suction cup at the bottom for you to stick to the shower walls, and it really sticks to it, you don't have to worry about it falling off. I left it hanging on the wall for 1 week and it stayed right where I left it. The battery life is very good. I used it for a whole week without having to charge it. The lights on the speaker also flash and change light while music is playing, which is nice. Volume is pretty powerful and clear, and it has decent bass too. Overall a great speaker for the price.
