NCH.
Noise Cancelling Headphones:
(Not DSP)

These headphones reduce the ambient background noise to allow you to listen to the program source peacefully.

The headphones employ microphones to monitor the ambient noise. These microphones are wired out of phase and feed a differential amplifier which generates an opposing signal to that of the unwanted noise. This signal then cancels out the unwanted background noise.
The headphones effectively remove noise such as blower noise, ambient noise, jet engine noise or music from another room.

The headphones are supplied with an aircraft adapter, so you can now listen 
to the film, or CD player without all the jet engine noise.

The headphones are folding and can be stored in the supplied travel bag.

Supplied aircraft headphone adapter.
