I currently have a set of Sennheiser PC 350 Siberia V2 and to be quite honest I am not to impressed particularly with the microphone part of the headset. I do not use them often but but on occasion do need something for gaming. So I was wondering separate microphone and headphones or all in one again. Because I use them so rarely I am not looking to spend much cash on either. So looking for suggestions and advice on either a headset or separate mic and phones.
