TRITTON AXPC True USB 5.1 PC Gaming Headphones with 8 strategically placed speakers, adjustable microphone The AXPC head phones (TRI-UA512) by TRITTON gives you true 5.1 surround sound in the comfort of a headphone for use on your PC through USB. AXPC has a total of 8 speakers, 4 in each ear cup and a adjustable microphone that is perfect for online gaming or internet calling. Your computer does not need to have a 5.1 sound card, the AXPC includes a built-in 5.1 audio controller. Sound is separated into 8 speakers, four in each ear cup (Center, Front, Rear, and Subwoofer). Integrated into the external audio controller is a specialized chipset that amplifies each of the 8 individual speakers. Software is included to simulate your audio source from Stereo to 2.1 or up to 7.1 surround sound. Select from 23 Different EQ settings to customize your listening experience whether it is a game, music or a movie. Each ear pod consists of 4 speakers, a dedicated front speaker, center speaker, rear speaker and subwoofer. This means when playing a game or movie with 5.1 sound the AXPC delivers true 5.1 sound. Others may claim 5.1 sound but it is simulated or emulated which means you will never get the true 5.1 sound like it was meant to be heard. Inline controls allow you to adjust the volume, mute and microphone mute.
