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 noise up to 87.4% (9db at 300Hz) when noise canceling circuit is switched on

13.5mm driver units

The drivers sit just outside the ear with the tip of the earbud small enough to fit into the ear canal 

for additional comfort, secure fit and sound blockage.

Ideal for:

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

Unique feature:

The 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. 

Passive function

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.
