+ Voice quality (the micro is better to wide when the microphone of my predecessors for far more money)
+ Sound quality (even if no Dolby Surround ultra super, I can thus distinguish "compass" that's enough for me)
+ Pass ability (is fully adjustable and fits superbly on his head, slipping only when strong movements)
+ Portability (you can quickly fold on glasses size and take wonderful)
+ Price (comparatively very cheap!)
[+ Skype (for me a plus on the edge to use with Skype very well and functions as Mute> /
Did the headset now almost half a year and several times over 8 hours at a stretch in use and am still very happy (and realize that at some point a little to hurt the ears begin, I think ...)
All in all: great part - strong buy recommendation!
