When you’re in the game, you’re “in the game”, and the Koss GMR-540-ISO-USB headset makes sure you stay there.
The isolation of the closed-back ear cups shuts out distractions while the wide frequency range delivers every nuance you need for a completely immersive 3D experience.
Go ahead, play all night. The 540’s lightweight design with a custom fitting sling means you can see your mission through to the end, no matter how long it takes. Over-ear Koss “D-Profile” earcups ensure a perfect seal and maximum comfort during extended use.
Even a lone wolf needs to communicate. The GMR-540-ISO USB features a detachable cord design and comes with two cords. One 8-foot cable with a boom microphone, and a 4-foot standard headphone cable with the Koss 1-touch microphone, both have USB connectors.
