Don't buy Razer!!!!!
I had the razer kraken pro headphones and they were garbage. They muffled every sound and they were very bass heavy, terrible audio quality. The microphone never worked and it felt like a piece of plastic junk.
I love my new sennheiser HD598 SE. Sennheiser also has great customer support. I bent the adapter for my headphones and they sent me a new one right away, no charge!
