ANC (Active Noise Cancelling) is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
ANC Headphones absorb ambient sound with Mic, process incoming sound waves and creates inverse waves to offset the noise.
These Headphones are designed and manufactured with the ANC chip, which is capable of reducing noise up to 35dB.
