The GSP 350 Gaming Headset from Sennheiser features virtual 7.1 Dolby Surround Sound and a closed-back design that reduces outside noises so you can concentrate on what matters most. The soft, memory foam earpads and adjustable headband provide you with comfort over long gaming sessions, while the built-in volume control knob offers easy access for adjustments. With the noise-canceling microphone, your teammates and enemies will be able to hear you clearly. On the other hand, should you prefer to stay silent, simply raise the boom arm to automatically mute the microphone. For compatibility with other platforms, you will need a separately sold cable. Also please note that surround sound only works with Windows PCs.
