The Surefire Harrier 360 is a USB gaming headset built around 360 surround sound processing, aimed at players who want positional audio cues (footsteps, gunfire direction, environmental sound) without needing a separate sound card or analog surround setup. Running over USB rather than a plain 3.5mm jack lets the headset handle its own digital-to-analog conversion and surround virtualisation internally, typically switchable on or off through software or an in-line control depending on the exact game or use case. Like most USB gaming headsets in this class it pairs cushioned over-ear earcups with an adjustable headband for extended wear and includes a boom or flexible microphone for voice chat, usually with an in-line mute and volume control on the cable. The USB connection also means it doesn't rely on a PC's onboard audio jack quality, which can be a genuine improvement over a basic analog headset on budget motherboards. Surefire's own manufacturer site wasn't independently locatable this session, so exact driver size and frequency response figures aren't claimed beyond what the product's own name confirms (360 surround, USB).
