This headset is a tactical headset that includes hearing protection and intercom between teammates. The headphones feature dynamic noise cancellation, which actively suppresses noise and reduces echoes. Speech Enhancement looks for speech in background noise and actively filters the noise to improve speech intelligibility and make conversations more comfortable. The ear cushions are made of silicone material for a better fit and are softer than regular cotton ear cushions, conforming to the shape of your ears. Even if you wear it for a long time, it won’t be labored. This product will bring you a better experience in gaming. Note: This product does not include a helmet and battery.
