The Turtle Beach Ear Force Stealth 450DTS. A wireless gaming headset with DTS headphone: X 7.1 surround sound, and with Superhuman Hearing. Wow, sounds like fancy stuff. Is it any good though? The answer is a resounding YES! 7.1 surround sound requires no explanation. The rest probably does. DTS is - in short - a technology that amplifies 7.1 surround sound; you don't just hear where a sound (like a gunshot) comes from. No, you can also hear what its distance is to you. Next, there's Superhuman Hearing, a feature that reinforces soft sounds. As a result, gun shots aren't completely drowned out by a tank that suddenly thunders past.
