SteelSeries 9H Gaming Headset

The 9H headset from SteelSeries is designed to enhance the competitive gaming experience with pro-level audio, extreme passive noise blocking, and a supremely comfortable fit. Built with Dolby technology and equipped with an advanced USB soundcard, the 9H offers a custom-engineered soundscape with a wide dynamic range. Components like high-grade mylar film improve sound clarity and eliminate distortion.

With a DJ-style closed design, these headphones feature a second internal enclosure that’s sealed around the back of the speaker. Combined with the ultra-padded ear cushions, this creates an unmatched noise cancellation experience, letting you focus on the sounds of the game and outmaneuver your foes. A retractable microphone (it hides in the left earcup when not in use) functions as an active noise-cancelling “smart” mic, picking up your voice over any background noise.
