Features

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 noise up to 90% (10 dB at 300 Hz) when noise canceling circuit is switched on1

Lightweight design with a built-in monitor function allows you to hear surrounding sound without taking off the headphones. Perfect for listening to announcements, flight attendants, or any external sound without the need to take the headphones off.

Soft and comfortable on-ear fit with pressure-relieving urethane ear cushions. Super compact foldable design for carrying and storing in the included premium travel case.

The headphones can operate as passive headphones when the noise canceling circuit is not activated. It allows the headphone to function as regular stereo headphones without using the battery.
