Noise Canceling on-ear headphones

Noise canceling technology

Noise canceling headphones reduce ambient noise and provide a quieter environment to
enhance audio entertainment. The headphones have an inside microphone on each earpiece
that work with an electronic circuitry to create an opposite sound wave to reduce wave.
Ambient sound is reduced by synthesizing with a sound in opposite phase produced by the noise
canceling circuit.

Reduces up to 87.4% (9 dB at 300 Hz) ambient noise when noise canceling circuit is switched on1.

Ideal for:

Loud, noisy environments – planes, trains, buses, work or dorms.

A supplied plug adapter connects directly to stereo or dual jack of in-ight music services3.
