After some searching, I have decided for the Platronics 478 price seemed still fine. Was very important for me, the Mute button louder. quieter and hang here are a nice gimmick, where the hang-up does not work with me in Skype. Because me I have but interferes in any way not further research into the cause, perhaps only a matter of attitude.
The workmanship is good and the installation simple, infect wait briefly goes. The sound is for a headset and a little music listening at work absolutely fine and the feedback from the person being called is very positive as the microphone seems to be reasonable.
For durability of the folding mechanism, I can not say anything because I use the headset exclusively stationary.
All in all, a well-functioning practical headset that does what it should, I würds buy again.
