The H10-13H Headset is the H10-13.4 headset for helicopter pilots, also with a coiled cord and a single plug. The H10-13H headset provides David Clark quality without the hot spots, clamping, or weight discomfort. It features a certified noise reduction rating of 23 dB and weighs only 16.5 oz. It features M-7A noise cancelling electret mic, and low profile volume controls with detent settings.

The Super-Soft, Double-Foam Headpad will improve the comfort and “wearability” of all H10-series headsets. It is wider and more tapered with 60% more surface area in contact with the head to dissipate headset weight. Its unique center “hinge” actually lets the headpad “breathe” for greater comfort. It also eliminates irritation while wearing button-top baseball caps.

The new Comfort-Gel Ear Seals have a patented undercut design and are 26% lighter and allow 30% more interior room for your ears, making for a quieter, more comfortable flight.

Earphone Type: Dynamic
