Good sound, sits well, battery power is also good. What is very annoying - no micro USB for load, so you must not lose him or in the journey not forgot the charger. (Use s Motorola HT820 when battery is empty you can use cable, and headset as konvetionellen headphones.) No wiring for emergency - less annoying. Even less annoying, but suspicious - glued-foam. You can not replace if it is worn / damaged him ... Because the notes give it 1 point deduction ...
