Noise canceling technology

Noise canceling headphones reduce ambient noise and provide a quieter environment to enhance audio

entertainment. The headphones have a microphone inside each earpiece that works with electronic circuitry to

reduce ambient sound by synthesizing with a sound in opposite phase produced by the noise canceling circuit.

Highest Quality Noise Canceling

Reduces up to 98.4% ambient noise (20 dB at 160 Hz) when noise canceling circuit is activated.¹

Articial Intelligence (AI)

Automatically selects the optimal noise canceling mode based on intelligent analysis of environmental ambient

noise.
