Overview
The David Clark H10-13.4 is a passive attenuation aviation headset, certified to a 23 dB Noise Reduction Rating under ANSI S3.19, using cushion seal and construction rather than active electronics to block cockpit noise. It pairs an M-7A noise-cancelling electret microphone with a low-profile volume control on detent settings for consistent, repeatable adjustment, and an undercut foam-filled head pad for extended comfort. At 16.5 oz and needing no battery, it is built for the durability and dependability a training fleet or rental aircraft demands, with dual GA plugs for standard general aviation installation.
