Hybrid Electronic Noise Cancelling features not one, but two microphones – one located on the exterior of the dome and isolated from the speaker (feed-forward) and a second internal microphone placed near the speaker (feed-back). The exterior microphone acquires the noise before it gets to the ear canal. Working in concert with the internal microphone, the signals are then inverted to produce a reverse, ‘anti-noise’ signal, resulting in unsurpassed active noise reduction performance. •Internal microphone signal provides feed-back noise reduction •External microphone signal provides feed-forward noise reduction •Peak attenuation, 30dB @ 150Hz •ENC attenuation range, 20Hz―1KHz •Up to 50 hour battery life (2 AA batteries) •Digital Signal Processor (DSP) provides clear communication and high fidelity audio DC ONE-X Series headsets are designed to enhance your personal comfort in the cockpit. The head pad, utilizing Outlast® technology, responds to your constantly changing skin temperature to help keep you comfortable. Outlast® technology proactively manages the buildup of heat and moisture to help delay the onset of sweat, helping you stay comfortable even during longer flights.
