the set will work with Android phone (Samsung Galaxy W) and Aux-in better than expected. The Bluetooth connection worked right away and can be produced by briefly pressing the button again. Telephony is functioning properly. But particularly positive is especially the music playback. The Phone to the AUX input was much quieter than the radio - traffic announcements have been formally dazwischengeschien. With the Bluetooth set the volume on the other hand fits perfectly. The transmission is well balanced amazingly free of perceptible noise and the sound quality. On top the handoff to the next track with double pressure on the button does not work only on the standard player as often described here, but even in the Spotify app.
