Summary: After getting these from Amazon for review via the Vine program I admit I was really pleased. I had been considering a high end USB headset and the Corsair range had actually made my short list. Admittedly I hadn't been looking at these top of the range ones but was very happy to be able to get these and try them out. I've drawn up a list of my pros and (possible) cons so you can see what I think.
Summary: The headphones are very well packed and are well built with a long strong USB cable. One of the first things to do before plugging them in is to visit - corsair.com - corsair.com/en-gb/support/downloads - and download the drivers needed to achieve true Dolby sound. Once the file is downloaded, just execute the program file then when the headphones are plugged into a USB port the drivers will install automatically.
