The Razer Kraken Tournament Edition THX Gaming Headset THX adds a new feature to sound with THX Spatial audio. Thanks to the THX in-line controller you can have 3D sound in PC games, making it easier to recognize sounds. For example, you can hear if someone is sniping 30 or 50 meters away. The Kraken TE is extra comfortable for longer gaming sessions, since the ear cups have a layer of cooling gel in them. There's also more room for the temples of your glasses, so wearing a pair of glasses while gaming is not a problem with this headset.
