Headsets : Studio vs Standard
I use the Sennheiser HD595 with a Antlion Modmic which turns it into a headset with an easy magnetic base. That way you get the great headphone sound with a nice microphone. Also I have the Xonar soundcard as well.

Pretty neat little thing, I waited for years before I found exactly what I was looking for. Best invention ever.
I've had a few gaming headsets before and they never matched up to a quality pair of headphones. Sound quality is limited and comfort is important when gaming for a lengthy time. I'd never go back. Had these for years. Also don't buy a desk mic. Some people sound fine with them but mostly they sound tinny when in an open room. If your mouth isn't close enough you get a crap input sound quality. Clip on mics are fine I guess but with the wires and annoyance of clipping it on every time why not just get something that works exactly like a headset does. Flip up and flip down.

My friend had one of these which was about £160 headset from Sennheiser PC350. The sound quality was crap imo. It was all muffled and quiet. I think I remember he sent them back because they broke so easy lol. Although these were closed ones not open which I dislike anyway. I think yours will be closed as well by the looks of it.
Maybe others have had better experiences with headsets than I have but I listen to a lot of music and play games so I wanted a decent pair of headphones that would deliver, I haven't found a headset yet that gives the same quality in sound.
