Logitech's G35 Surround Sound Headset is jam-packed with features including Dolby surround sound; user-definable profiles; a spring-steel headband; and a USB interface that keeps the audio signal in the digital domain until it reaches the headphones. By performing the digital-to-analog conversion in the headphones, Logitech eliminates any chance that the audio will be polluted by electrical noise radiating inside the computer.
