Purchasing this Sennheiser headset corresponded to a technical choice determined by comparison, but not by comparative listening. I finally chose this model "mid-range" in "at risk" the coup after being disappointed by a headset of another brand. My usage is versatile. Skype Communication, listening to music, youtube video and other movies and TV shows viewed on PC, and some good video games "dynamic". Well, I was pleasantly surprised at the quality of the sound, responsiveness of the helmet with the games, very good reception of my correspondents Skype, excellent musicianship very eclectic tracks I auditioned working or lounging on the Internet, and listening to the radio that I practice often. In short, quite impressive sound quality for the price and quality of the helmet in its materials, the ability to raise the microphone that cuts out then the strength of the components, the comfort of the bow too. Only downside which also depends on the morphology of each, I think it is important to adjust the hoop, otherwise the pressure on the earlobes ends quickly become unpleasant. That is why I have not given all the stars. But otherwise, this headset provides an excellent value choice without major default only adjustable fit and then we frankly forgets that uses the same helmet in the heat of the highly addictive games! I did try by friends, they were all packed !!!
