I have long been in use and I can only rave about this headset is now about it. The battery life is huge, especially with the external battery into the casing. The voice quality is also very good and the volume pleasant. Best I liked the very pleasant sitting by the non-standard terminals in the ear. Just as I wear glasses have otherwise have to suffer at all headsets pressure through the outside of the ear extending strap plus my temple. Since it was set here in a different version, eliminates the pressure and hours of wear is possible. By the flyweight and the pleasant sitting there is even happening to me, I've forgotten it. My conclusion about the product, everyone should have one;)
