I could also try this Bluetooth speaker. Let's start with the externals to: Matt Black, rubberized surfaces acting, actually a real Händeschmeichler. Diameter approx 8,5 cm, height 5 cm with suction cup. Diameter of the suction cup: 7,5 cm, strength: bomb hard. The delivery - as always with TaoTronics - in a cardboard box, no plastic. A round plug and not the usual microUSB connector that was used for the connection of the charging cable, has in my opinion a reason in the water resistance: the jack for the circular connector is easier to seal and probably more resistant to corrosion. The socket is also still closed with a cover made of silicone-like material. Sound: -or did not sound, the question here. Basically have speakers which must withstand humidity, no particularly great sound (or cost a fortune ..) Nevertheless, the speaker sounds fairly pleasant, with a quite distinct directivity and a fairly large volume. Bass are present and can still be reinforced by corner effect in the bathroom. In addition to playing music, you can use the speakers as a waterproof kit. Here, of course is good, your voice comes out the other end a little quiet 'over (which is probably due to the encapsulation of the microphone ...) Conclusion: In terms of the price, the portion is a clear recommendation: once for the bathroom and secondly as outdoor speakers, which can sometimes abkriegen some water, such as a hands-free speaker for the bike, or as a PA on the beach or at the swimming pool - or even when camping. Compact, robust and also takes a few splashes of water not bad.
