Heya Vegas,
I was talking about such stuff, but more Sony, Philipps or other brands like this. But I've search for the beyerdynamics, which is the apparently best brand if you wont spend 500€ and more, and I found some issues and therefore I'll grab huge (open?) wired stereo headphones and a simple mic as deskstand. ;-)
I think, if I didn't has to be connected while going 4 a rhum to the kitchen, I don't have to use a system with headphones and mic in one device too, esp. if the most of them has a rly bad quality compared with simple HiFi-Headphones for the same price.
Infact the quality of headsets is a major issue, bc I was reading in some forums many complains about sharkoon, medusa, roccat etc. If you dunnot spend 150€ (Sennheiser PC360) or 300 (Beyerdynamics MMX 300), nothing can beat the combo of HiFi-HP + desk mic...
