David Clark headsets are known for their durability, but until now have focussed on no frills practicality.
The DC One-X brings improved comfort, active noise reduction (ANR) and Bluetooth connectivity to compete in the top tier headset market dominated by Bose and Lightspeed.
Ensuring you don’t forget the heritage, the One-X still comes in the legendary ‘David Clark green’, and although lightweight, the build quality is of the same high standard for which David Clark is known.
Noise attenuation is accomplished by what David Clark calls Hybrid Electronic Noise Cancellation (ENC), whereby noise is sampled by two microphones, one inside, and one outside the earcup resulting in a noise reduction quoted as 30 dB at 150 Hz. David Clark’s typical passive noise reduction (PNR), which I already thought was good, is about 23 dB. In short, the noise reduction is excellent. Interestingly, although not suitable for all open cockpits, David Clark donated One-X’s to Flying for Rhino and Conservation who operate Bat Hawks, and the ANR technology is sophisticated enough to cope with the wind and noise in the aircraft.
The plush leather ear-cups with memory foam are wonderfully comfortable and cool, and adjust to seal around your ears well, even over a cap and sunglasses, and the clamping pressure isn’t too tight. The head-pad material, dubbed ‘Outlast’, is also designed to enhance comfort and there is very little pressure over your head. The mic boom can swivel a full 180 degrees and so can sit on either the left or right. The audio quality is great and transmissions are crisp and clear.
The control module linked to the jacks, controls volume independently to the left and right and provides Bluetooth connectivity. Bluetooth pairing is simple, and if you are listening to music, it automatically drops for radio communication. The batteries are said to last 50 hours, and the headset operates as a standard PNR unit if the batteries are drained. You can set the module to automatically turn off when it is not being used so that you don’t arrive to flat batteries, but strangely this isn’t the default setting, and the switch is hidden away behind the batteries.
As soon as you take the headset off, it folds up neatly to occupy noticeably less space than previous David Clark models.
The DC One-X is David Clark’s compelling answer to the premium ANR headset market. The company’s exceptional build quality remains and the new technology is superb, and for R18,999 the One-X is slightly less expensive than some of its competitors.
