What is the David Clark DC One X? 

The David Clark DC One X2 is an ANR-style headset where ‘ANR’ means ‘active noise reduction’. In the earlier styles, the only option has PNR which means ‘passive noise reduction’ where the ear cups are the only layer to manage external noise. David Clark has included the ANR feature to combine the direct passive style with the newer technology of hybrid electronic noise cancellation. The David Clark DC One X still is recognizable in the classic David Clark green, sporting many new features to enable pilots a seamless communication experience including a Bluetooth feature for pairing with any compatible smart technology gear.

Where are David Clark headsets made?

The David Clark company inc3 remains a privately owned company based in Worcester, Massachusetts, USA. Originally a textile company, throughout its life has pivoted into aviation communications and space-type equipment including the famous green headset. If you ask any older pilot, most either had a David Clark headset or yearned for one and the fact that the company remains today is a testament to the popularity. The company’s best known for its development of the noise-attenuating headset and associated boom microphone.

How much does the David Clark DC One X weigh? 

Any pilot will tell you that functionality and weight are important when choosing a headset, especially when spending many hours flying in smaller aircraft. The David Clark DC One X is slightly lighter than some of the other big name ANR headsets coming in at 12.3oz around 14% lighter than some of the Bose options. With the ongoing development in materials the ANR headset assists pilots to reduce errors in communication such as read-back, hear back, or no read-back situations. It is a long way from the cumbersome leather flying helmets originally designed to protect the pilot from an open windy cockpit which later had modifications of throat microphones and earphones built in.

Is the David Clark DC One X headset worth it? 

I love this question as it allows us to tell a story about hearing … or the lack of it! The short answer is ‘Yes!’ the David Clark DC One X headset is worth it. All veteran pilots have spent time in louder older aircraft before there were noise complaints, when people just accepted the airport was there first. On top of this, the headset technology was not where it is today, so noise canceling was not as good. Now wind it forward to what happens to age-challenged pilots now.

I have a female pilot friend who sums it up perfectly. The drone of the engine noise has left her struggling with low-tone sounds and it is reported that her partner speaks in low tones. That my friends is the recipe for ‘domestic deafness!’. The moral of the story is to invest in your hearing by protecting it from the start and also save any miscommunication in the home!

If we return to the basic ICAO competency framework of communication, there are two observable behaviors that ensure this competency is met and the highest level of safety can be maintained. We have scrutinized these, and a pilot must be able to ‘convey messages clearly, accurately, and concisely and ‘Listen actively and demonstrates an understanding of important information’. This is not a drill; you cannot have your equipment affecting this competency. One missed radio call could spell disaster and we urge you strongly to always be developing ways to communicate better.

Always clarify information if you are not sure whether it is coming from air traffic control or another pilot. Miscommunication has been the cause of accidents in the past such as the Tenerife air disaster7. Honor the lost and maintain superior communications … you deserve a good headset!
