The Ear Force X4 is the next-generation of Xbox 360 wireless headphones designed by the experts in gaming audio technology - Turtle Beach. The core design of the X4 is based on the popular Turtle Beach Ear Force X3 wireless Xbox 360 stereo headphones. Both the X3 and X4 use infrared wireless technology to transmit the game audio, however the X4 has many improvements, including a more powerful transmitter, headphones designed for greater comfort, and Dolby 5.1 channel Surround Sound to reproduce 3D positional sound cues that are otherwise obtainable only with surround sound speakers.

The X4 transmitter includes a digital signal processor (DSP) with an optical digital input that connects to the Xbox Dolby Digital audio output. The DSP decodes the Xbox Dolby digital stream into 5.1 channels and then uses Dolby Headphone post-processing with Head-Related Transfer Function (HRTF) technology to create realistic surround sound on the X4 Headphones. The result is an astoundingly accurate surround sound experience with the freedom to move around with wireless headphones. A unique Bass Boost sub-woofer filter network accentuates low frequencies for deep bass response from any type of input signal - music, games, movies, etc. - regardless of whether or not the source has a sub-woofer signal.

Features

True, Dolby 5.1 Channel Surround Sound: Gamers use visual and audio cues to help them excel in high-intensity gameplay. The X4 Dolby Headphone technology recreates positional audio that can only otherwise be achieved with a true 5.1 speaker system - so even though you're wearing headphones, you can actually hear enemies as they sneak up behind you, bullets fly by your head and other 3D sound cues in the game.

Dolby Pro Logic II: The X4 also decodes Dolby Pro Logic II signals and expands stereo signals into a wider sound field that seems to originate from outside of the headphones. So it even improves the sound of games and audio sources (such as music) that might not have Dolby Digital soundtracks.

Game Audio + Xbox LIVE Chat: Traditional, single-ear headsets place the Xbox LIVE chat conversation in one ear, degrading the game audio into a mono experience with the other ear. The Ear Force X4 mixes game audio and Xbox LIVE communication in the headphones, so you can hear the game in surround sound while chatting online. Separate volume controls allow you to independently set the game and chat levels.

Premium Sound: While most headphones utilise 40mm speaker drivers, the X4 Headphones are designed for premium sound with oversized, high-fidelity, 50mm drivers powered by low distortion DC-coupled amplifiers that deliver smooth, deep rich bass sounds and crisp high frequencies to make game sounds come alive.

Chat Boost Dynamic Talkback Expander: The headphones automatically adjust Xbox LIVE chat levels during loud game moments, so chat from teammates isn't lost in exciting parts of the gameplay. When the game volume quiets down, the chat level smoothly returns to the normal volume setting.

Comfortable for long-play sessions: The X4 Headphones are lightweight, with large, deep, soft ear cushions that are easy on your ears, so you can play for hours with no discomfort.
