I've been using this now for a few months and I've found it to be very comfortable, the headset adjusts in height and fits on my head very nicely.
The quality of sound is very good for gaming, I'm not sure what the other guy is using these for (base??) but they state they are gaming headsets and work brilliantly in TF2 and L4D1/2. I can hear where the enemies are coming from and has a handy sound adjustment which you can tweak easily.
The cable is reasonible although possibly could be a tad longer.
Most importantly mic quality is good, my team mates can hear me perfectly which is what you want from gaming headphones.
My only real annoyance is the mic being on the left instead of the right, perhaps this is normal but I would feel more comfortable with it on the right!
I would say worth it.
