I use this headset frequently and it works well. The sound is excellent - as a Bluetooth adapter to the AUX input of a hi-fi system I miss neither highs nor lows. Unfortunately, the headset is not charging when it is in use. This limits the usability but an unnecessarily. Schön would have been if the headset would be to load the currently used in phones microUSB port - you need mini USB on the headset.
..wegen these things unfortunately a point deduction for the otherwise good device.
