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
Artificial Intelligence (AI)
Automatically selects the optimal noise canceling mode based on intelligent analysis of environmental ambient
noise.
