I have the 1300's
The sound quality is good on them and they are comfortable to wear, even for long periods of time (Initially I found them quite tight, but after wearing them it gets better or you can "stretch" them my putting them on your PC case for awhile or on a mannequin).
I am however on my 3rd set of 1300's after the first 2 pairs had dodgy connections around the volume / mic mute box. Overclockers have replaced both very quickly however, so cannot fault them. I have read of a few others with a similar issue. I have to move my headset / cable around a fair bit, as my cats probably can't be trusted if I just left the wire hanging / dangling so probably nothing to worry about if your headset isnt moved much. Hopefully the issue will be resolved on this pair.
