Even the transparent design is unusual and a unique selling point. The transparent plastic but if you look closely fine scratches, but fortunately you do not see at distance. Rounding out the design with a red LCD display, which can be seen only in the on-state; the display will then choose to measure the time, the FM Transmitter or information on song in SD mode. Whether the transparent design like, of course is a matter of taste.
The sound qualities are the class of Bluetooth-compact speaker in order; Medium- and high tones are clear and as long as one does not simultaneously ausreizt speakers and source player up to the absolute top. Even the bass is satisfactory in volume and intensity. However, I've just failed a slightly weaker tone in comparison with the normal (non-transparent) speakers from the same manufacturer. Possibly it is because of the resonance properties of the transparent housing. In general should also be clear that a compact speaker in this price range is not pumping hifi.
The Bluetooth connection can be established easily with this device, keeping 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 support the unit next to the most 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 the sound quality of SD directly a bit better than occurs 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 here a good speaker in an interesting design which delivers a passable sound and is widely used even with the extra functions. Who does not want to necessarily have a translucent design, goes to my assessment but with the models BX-100 or BX-300 from DB Power sounded excessively even better.
