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. Specs: •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) •Dual Voice Coil transducer for Fail Safe operation •Digital Signal Processor (DSP) provides clear communication and high fidelity audio
