The communication between the commands and keys / smartphone fold perfectly, I had here so far no problems (use exclusively the Goolge Play Music app).
Loud and soft is adjusted by prolonged pressure of +/- keys Pressing these only briefly as a title change to backward or forward. Start and Pause a button, call answer / reject / redial is also a separate button. The individual functions can be reached by a short, long or double pressing the speakerphone button.
Charging is done here via included USB cable. Unfortunately, however, the connection to the speaker no micro USB but a normal round.
The sound is of course not as a Bose system. Who expects such sound must also pay well and like more than 300 of his bathroom speakers. These are but a speaker of a significantly better sound makes for me as a normal radio. The speaker even manages bass pretty good play. For my shower experience this sound enough fully.
When charging with the supplied cable, a red LED lights up slightly below the ON button.
A star is omitted due to the following points:
- No 3.5mm jack to just quickly what to connect without Bluetooth connection
- No micro USB cable for charging
- In addition to the suction cup could still hook you possibly can accompany the use of shower curtains
but otherwise fully recommended.
