Right well I'm officially a Razer fanboy...
I got the Barracuda 5.1 Headset
After a few days of usage here are my thoughts...
Its great.. the surround is accurate (may be also down to my x-fi card too) and clear.. The mic is detatchable which would be a great feature if it wasnt for the fact i pulled it out in game, shouted spy and no1 heard me haha
But the mic seems clear and crisp when its in propperly...
Its got a MASSIVE volume control unit (about the size of a small mouse) and you can adjust the volume of each channel

Sound quality is the main thing I love about this headset.. Its got good all round response... bass is a bit weak though... but I can live with that
Finally, I got the Razer eXactMat to go with my razer mouse... and it actually makes a difference! tracking seems more intuative and controllable which for gaming is the most important thing right?
I use the speed side as it glides but the control side is also good for other apps...
When they make a razer desk, im in
Happy fanboy
