GMR-540-ISO Headsets

Featuring new custom tuned elements and closed-back design, the GMR-540 ISO Gaming Headphones deliver the isolating 3D sound game developers intended.

An ultra lightweight design with an all-new custom fitting sling allows the GMR-540-ISO to be worn for hours of gaming and extended use. The over-ear design has the iconic Koss “D-Profile” earcups that mimic the shape of the ear to create the perfect seal and lasting comfort.

The GMR-540-ISO also features a detachable cord design and comes equipped with two cords: an 8-foot extended cable with a boom microphone (with separate audio/voice plugs) and a 4-foot standard headphone cable with the Koss 1-touch microphone (with standard 3.5mm plug).
