the device has a super sound. Rich bass About the button display on the remote control display the MP3 folder / tag. Bluetooth works fine. The sound is very good, it virtually noise. With Forward and Back buttons on BoomBlaster can also control the smartphone. Radio reception I can not judge because I hardly listen to the radio. Did it with another provider gekauft.Trotzdem I find the price a whole as too high. As for the technology - strong buy recommendation.
