Shortcomings exist on the telephone and in radio mode. The quality of the phone is less than optimal, the sound is slightly distorted and not very clear. Listening to the radio - to the device must be connected by cable to the smartphone - will transmit the radio signals of the mobile phone as a background noise with a slight rattle, because the speaker is located close to the phone due to the short cable length to. The call volume is good and sufficient, however, I have only tested with less side or background noise.
All in all is quite well suited as a portable speaker for outdoor pass or for the joyful Mucke while showering the Bass Disc. I have not regretted the purchase !!!
Oh yes, a soft case, incidentally, was also there ... so only because it was described differently in another review and this was not mentioned in the description of delivery. But no manual was there, but in the smartphone age one has the better anyway as a PDF download on the phone, shrill!
