Extra-large binaural ear cups provide both comfort and stability, ensuring an airtight seal over the user's ears for clear speech reproduction and high-quality music playback. The open-speaker design also provides users with a 360-degree soundstage, emulating a surround sound speaker system through three-dimensional panning and stereo width techniques. An extra-thick single-sided cable is provided to minimize tangling and prevent the overall lifespan of the headset, with dual-3.5mm inputs for mic and headphone connectivity. In-line volume level and microphone muting controls are included for quick adjustments during gameplay, while voice recognition technology is available for keeping track of teammates in multiplayer gameplay. In addition, the PC 161 supports voice-over-IP internet calling, and is supported by conferencing applications such as Skype and Google Talk.
