DCH10-21 David Clark Headset
In 1975 David Clark Company introduced the first headset specifically designed to provide hearing protection for pilots while also providing clear, isolated reception and crisp transmission at normal voice levels in a noisy aircraft.
Pilots have trusted the green domes of David Clark Company headsets for over 25 years. Their high-performance products are now equipped with several new features to enhance pilot comfort: super-soft, double-foam headpads, comfort-gel, 'undercut' ear seals, and a smaller, lighter battery pack with auto sutoff for ENC models. Find out for yourself why quality-conscious pilots will accept nothing less than the #1 Headset in Aviation.
