Good headset with few flaws

I own that, in May 2012 newly presented, PC 323D now worn since last week (as a replacement for my old Sennheiser PC 350) and have been around for about 20 hours. Within this period, was also a long Saturday night with Battlefield 3, so I the PC 323D ingame even several hours in TeamSpeak 3 and Skype could test.

PLUSES:
+ The 7.1 USB sound card does a very good job in terms of sound quality and in particular the spatial location (of opponents and noises).
+ The headset is much lighter than my old Sennheiser PC350. This is very comfortable to wear on the head and comfortable.
+ The open design is ideal for long sessions, hot ears are past. In addition, you are not completely isolated from the environment and listen to his game still as in a closed headset.
+ The microphone provides a very good voice recording and mute by folding is a good design idea.
+ Compatibility with games is very good. You just have to install to start the supplied Sennheiser driver. After the headset works instantly with any application.

Cons:
- If you as an adult has a large head (like me), then you have the ears pulled out of the headband a bit, so they sit at the correct height. Since the ear cups thus at the same time continue to turn inward, creating a pressure point below the earlobe. This detracts from the otherwise good comfort of the headset for "Großkopferte".
- If you wear glasses (like I) (with hangers made of plastic), then the relation of the earcups produces a quitschendes noise, through the resulting friction when moving the head.
- The volume controls you by turning on the right earpiece. Unfortunately, the degree of increase or decrease is too large even when only small rotations, so that one is unintentionally too loud and too quiet. In addition, this kind of volume control is not very intuitive, so you have to try again and again in what direction loud and in which was again silent.
- Listening to music, there are certainly better headset. In particular, the bass is me as not strong enough.

CONCLUSION:

4 of 5 stars because it is a very good piece of hardware gamers from Sennheiser. It's worth it, in my experience, spend a little more money and get quality for it.

PS If anyone here from Sennheiser reads: In my pre-predecessor headset, the Speedlink Medusa 5.1, there was a holder for the headset to. This was a very simple plastic arm with a glue dot (like a big towel hooks's bathroom). The fine could attach to the side of the desk and the headset hanging there on the bracket. That would be my wish! There may also be something like Higher quality, an appealing product presentation even after unpacking. :)
