Review on 🚿 Waterproof Shower Bluetooth Speaker, MIFA A4 - Portable True Wireless Stereo Sound with Built-in Mic, TF Card Slot, Suction Cup - Perfect for Running, Golfing, Cycling by Greg Quinit

Five stars because it's a great solution for the price. If you want the best sound, you have to spend significantly more money. It's not stereo, it doesn't have a deep pounding bass, but other than that the sound is really great. I put in a memory card with three folders (140 songs) and it plays them all back to back for several hours. I haven't looked into the science, but I'm pretty sure the battery life is at least 15 hours this way. Bluetooth will put a much heavier drain on the battery but I reckon it will still last at least 10 hours. I can turn it on and take it anywhere. I can put it on the surface or hang it anywhere. Don't worry about the water - and it's a beautiful item. That's a lot for less than a large pizza!
