I forgive for this device only two stars. I wanted only awarded only one star. But I give one more for the processing and design. The remaining three stars are missing, because the unit does not gain a hearing enjoyment, and this is particularly important to me when I listen to music. If I experience dropouts repeatedly, then I just do not have enjoyment of listening to music. These dropouts occur, for example, when I'm surfing with my laptop in parallel on the Internet and, although I listen to music via the smartphone and even the flight mode was activated in order to avoid that certain background activities interfere with the Bluetooth connection. In this respect, I can not recommend the device. Better to connect his smart phone via a cable to the stereo. Then you also have real musical enjoyment.
