I refer in my brief review not to the cuboid, larger speakers, but on the small round, with colored rubber sheathing. As I unpacked it, I was pretty excited about it, because on the one hand it has a detachable suction cup, by the way, extremely strong or similar to tiles holds (got it almost not gotten, it thumbs up!), and secondly, the rubberized buttons are quite large and have a good pressure point. When you turn on the speaker gives a short but (caution) but quite loud "POWER ON" on its own, parallel course when turning off "POWER OFF". Good Idea. Bluetooth connection goes smoothly and without interference. The first application will and reason to buy it, the speaker in the shower "to pinning" was. More than that the speaker as far as for a shower is dense and can be quite noisy, can be to actually say no more. The bass is naturally not comparable to big boxes, but I find it quite appealing for the size. It seems to me as if in front of the bass punchy, if you have fixed the speaker with suction cup, but can only be an illusion. Battery power in the middle range, nothing special, neither positive nor negative surprise. Solid. All in all for the price definitely my recommendation to buy, you can not go wrong and the small Brüllwürfel must be in front of others in its class hide under any circumstances.
