Actually, it's a simple idea to build a "watertight" speakers. But really seems to have not yet been enforced, the subject of "Music in the shower". With this Bluetooth speaker can change that, because similar absolutely effortless handling in combination with a (Bluetooth-enabled) Smartphone and a large suction cup holder as make it possible. Of course you can use the speakers in the dry environment. I'll use it for example even in summer on the terrace. Since it is then not matter if it suddenly begins to rain ... The sound quality is fine for the size and I was surprised at the calls to the "nub" can be performed even reasonable. The internal (non-removable) battery with the supplied cable (not standard) to load via USB (duration about 2 hours). The icons on the gray buttons provide no puzzles and the initial search for and pairing with a music provider happens easily. The "nub" is recommended in any case!
