The speakers came in a small package, in which the speakers themselves, a Anleiung (also in German) and a USB charging cable were (without mains plug).
I was not expecting much, and certainly not at a battery capacity of 500 mAh.
I was taught!
First charging time about 1.5 hours on the PC.
Since then runs the speakers without even went empty the battery, and that was over a week ago, and I bathe every day for half an hour while playing songs from the smartphone.
The speaker is abolut impervious to water, as long as one does not dip it into the water. So while showering absolt harmless.
The sound is top class 1A, as many other speakers can learn a lot.
The coupling with the smartphone and operation are simple. Keys to nächseten / previous song play, Play / Pause (volume up / down), Answer call, everything available and easy to use.
It's not only a speaker, but also has a microphone, speakers, and so in a speakerphone.
Not just for the bathroom ideal, but also in any other area where you want to listen to music or want to acquit.
The suction cup holds quite well, little tip: When suckers just do a little hair spray on it, and then they keep Bombenfest permanently.
Strong buy recommendation on my part, especially at the price.
