Description
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 ear canal to pick up internal sounds and produce anti-noise again to twice cancel the left noise. 3. Ear caps prevent 90% noise going to ear canal. Pick up the two headsets from the charging case, and they will be paired automatically. Then simply enable bluetooth connection on your mobile phone to pair the device with your earbuds.
