A long-standing leader in its field, this is one of the jewels in David Clark's civil aviation range.
The DC-ONE is a concentrate of technology, weighing in at just 349 grams.
This weight gives you access to a state-of-the-art headset featuring hybrid Electronic Noise Cancellation (ENC) technology,
a heat-absorbing "Outlast" fabric head cushion to keep you cool and comfortable during the flight.
And Bluetooth technology lets you connect your phone, tablet, MP3 player or other compatible device.

Easy to use.
 
The front of the control module features individual left and right volume control, the power button and the Bluetooth control button. 
On the back, beneath the battery compartment cover, we find a Mono/Stereo selector and a second selector for the automatic switch-off mode (after 5 minutes of inactivity if the headset is unplugged).
The headset is powered by two AA batteries, giving 50 hours' autonomy.
In the event of a power failure, the headset switches to passive mode and the volume control to maximum.

Your DC ONE-X headphones feature hybrid Electronic Noise Cancellation (ENC) technology.
This anticipatory noise suppression is achieved by an external microphone in the ear dome, isolated from the loudspeaker.
The external microphone picks up noise before it reaches the ear.
Return noise suppression is performed by the internal microphone.
The signals are then inverted to produce an inverse "anti-noise" signal.
This hybrid technology results in unrivalled active noise reduction performance.
The DC ONE-X features advanced comfort technology with an Outlast fabric head cushion. This technology responds to your skin and its temperature variations to help you stay comfortable during the flight by managing heat and moisture build-up to delay the onset of perspiration.
It absorbs and stores excess heat to keep the cushion and the top of your head cool, then gradually releases heat as conditions change (see illustration).
The net result of this advanced temperature management, when combined with a ventilated head cushion design, is greater comfort and enjoyment on long flights.
