Review on Kayinuo IPX7 Waterproof Shower Speaker with Enhanced Bass and Built-in Mic - Portable Bluetooth Speaker for Outdoor Adventures by Wendy Key

A very simple speaker that does the job. I'm not sure how long the battery will last, but it lasted me 3 hours. It's a lot bigger than it should be and the sound is what you'd expect for the price range - not bad for the outdoors (I use it kayaking). on the water), but nothing I want to hear at home. Setup and pairing was easy. The carabiner is complete junk - fragile plastic that's difficult to attach - and nothing bigger fits in the hole.
