The Faro(c) G2 headset with active noise reduction is designed for pilots who take flying seriously. The G2 headset with ANR reduces cockpit noise up to 52 dB. The Faro(c) G2 reduces ambient noise by combining passive noise reduction (PNR) with active noise reduction technology (ANR). Active noise reduction is achieved by placing a microphone inside the ear cup that listens to ambient noise and generates ""anti-noise"" into the speakers to cancel out unwanted noise.This Faro(c) G2 with ANR headset (EDMO# G2-A-BLACK) is black with dual GA plugs.
