These are limited edition Call of Duty Black Ops Tritton gaming headphone. Maybe missed priced. Amazon are selling them for £29.99 which is extremely cheap for Tritton. They are based on the Tritton AX Pro and have the same true 5.1 surround sound they have. These do NOT come with a audio decoder box for PS3 and Xbox 360 they only work on PC only with a compatible 5.1 sound card.
Get them while they are cheap and in-stock.
The ASIN code matches the one on the US Amazon site so you know they are real.
