The sound qualities are absolutely fine for the class of Bluetooth-compact speaker; Medium- and high tones are clear and as long as one does not simultaneously ausreizt speakers and source player up to the absolute top. However, even with use of good ninety percent of the maximum volume of the Bluetooth-to-play device, the speakers in my opinion is loud enough. Even the bass is satisfactory in volume and intensity. However, still it should be clear that a compact speaker in this price range is not pumping hifi.
The Bluetooth connection can be established easily and also holds several meters, ten were not a problem here. During playback, the link remains constant and uninterrupted. Also, the basic setting of the functions is not difficult. The somewhat spartan user guide is even more enjoyable and useful course.
When playing SD device supports popular formats such as MP3 and WMA. Although in the description always from TF card (Trans Flash) is spoken, these are actually almost always compatible with SD cards in the test worked both an old Class 2 SD, and a UHS-1 properly. Subjectively me is the sound quality of SD directly even a bit better than before via Bluetooth.
Works quite well then the radio function with the built-in antenna. If you change the location a bit, you can get all the big stations without interference pure. You can freely improve reception by einstöpselt the supplied USB cable (or another) into the USB port and used as an antenna. Basically, I'm with the services than radio but satisfied.
All in all, you get a nice package here, beyond its performance over the simple speaker clearly. These voices design, processing, sound and battery life.
