Active Noise CancellationHybrid 3-layer active noise cancellation. 1. Outward-facing microphone detects external sounds and counter with equal anti-noise to reduce the environmental noise up to more than 35dB. 2. Inward-facing microphone listens inside the ear canal to pick up internal sounds and produce anti-noise again to cancel the left noise. 3. Ear caps prevent 90% of noise going to the ear canal.
