After reading my comments of the headset through here, I thought a good replacement headset zuhaben found. Since my old Sennheiser PC151 is currently unavailable on Amazon, I chose the PC 320 here. The difference between the two headsets is easily explained - the Ohrposterung. While the PC151 small ear poster has lying on the ears has the PC 320 large pads which abut around the ear to the head. Unfortunately, the pads are not thick enough for the PC 320, so that the ears rest on plastic headset - this is really unattractive in the long run, since the small fabric does not help inside. The ears do so unfortunately after prolonged use of the headset to hurt - with prolonged use, I mean, for example, a film, a raid in WoW or just surf for an afternoon at and listen to music. Unfortunately you notice the headset and that is unfortunately very ugly.
Positive on the headset PC 320 is the operation - his microphone can seem by folding (ie exhibit), which just when a person enters the room and wants to talk is convenient - you do not talk before anyone else because you forget to mute itself, folded micro and rest. The volume control on the turntable the right ear cup works great and very intuitive.
The sound of the headset is typical of Sennheiser - no better than other headsets and no worse, just wont be great as always. The Micro is not as good as the the PC151 but still solid.
All in all, this headset for me a bad buy - "over ear pads" are not my cup of tea. Aching ears and lack of wearing comfort are simply out of place in a headset, as well as the brand name does not help.
