I purchased a bluetooth shower speaker from the Mashable shop for about $20. There was a suction cup on the back but it had a proprietary charger and a battery life around 4 hours. After the fifth time the battery died, the proprietary charger wouldn’t keep a stable connection anymore. Then, I was on a search for a replacement.
I looked at small bluetooth speakers from Bose, JBL, Beats, and Ultimate Ears.
