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

later I wanted a speaker with a good battery, Bluetooth and a wired stereo input, which this one has. The first problem is that there are no instructions on how to set up bluetooth in the "user manual". The second problem, and the killer of the deal, is that it sounds awful like the speaker is using a toilet paper roll: squeaky, rumbled, distorted. This applies to any volume. The third problem, the volume control doesn't work very well. Ten minutes was enough; back to revain it's coming!
