For Christmas last year, Amy gave me an Abco Tech Waterproof Wireless Bluetooth Shower Speaker & Handsfree speakerphone for one of my gifts. 🙂
Most days, I use it for 10–20 minutes, mainly for 89.3 KPCC. Music sounds good, too.
After a couple of months, it finally needed to be charged because the battery indicator was low.
Solid, great suction, and sounds good (considering the environment and acoustics). I like it.
