David Clark's quintessential H10-13.4 Mono Headset has been one of the industry's most popular aviation headsets for years - and for good reason. With its super-soft, double-foam headpad and trademark undercut gel ear seals, the H10-13.4 provides an exceptional level of comfort for hours of easy wearability. Its noise-cancelling, M-7A amplified electret mic eliminates unwanted background noise for crystal clear communications quality, while the headset boasts an impressive passive noise reduction rating (NRR) of 23 dB. Weighs just 16.5 oz. (sans cord assembly) and comes with David Clark's legendary 5-year warranty. A modern, optimized version of one of the best headsets the aviation industry has ever seen.
