Product Features
Sennheiser offers two series of headsets designed specifically for use in cockpits of commercial aircraft. The noise cancelling 26 Series is designed for noisy cockpit environments, while the lightweight 46 Series is suited for aircraft lower ambient noise levels, such as modern jets. Both series of headphones come with the same type of exchangeable boom microphone and cable components - a great benefit for all air fleet customers.
