So has anyone tried on these new DC's
Yes. I just bought one. Here's my report:
I had a chance today to fly with my new DCPro X today. The aircraft was a Piper Warrior. Let's just say I'm impressed.
My Telex 50D began failing earlier this year. Interestingly enough, the straw that broke the Camel's back for me was when, trying to get an IFR clearance by phone, I found the phone/audio interface no longer worked. I hadn't used this functionality for more than 5 years but with the move from Colorado to North Carolina, it became important again. I considered having Telex refurb the headset but ultimately decided against it.
The goal today was a simple one. Try out the headset - fit, comfort, noise attenuation, Bluetooth smartphone connectivity (both for calls and music). Compare it to the Telex (which I brought with me), especially with regard to the active noise attenuation.
For those who are familiar with the heavy clamping pressure of David Clark headsets (the reason, despite their reputation, I never flew with one), this, as the saying goes, not your father's Oldsmobile. The headset weighs in at less than 8 ounces and there's no clamping pressure to speak of.
Passive noise attenuation is, for all intents and purposes, non-existent. That was expected since many of the higher end ANR headsets have poor passive noise reduction. On top of that, the DCPro has a "supra-aural" design; it sits on top of the ears rather than cover them. In fact, there's a "passive" version of the DCPro which David Clark specifically warns was made for the commercial/transport jet market and "is not recommended for fixed wing, piston engine aircraft. To balance that, David Clark claims the battery life for the DCPro is up to 50 hours. I'm planning on letting the batteries run down completely the first time to get a sense of how long it continues to work after the switch starts flashing red and a low battery warning.
Active noise reduction ("Electronic Noise Cancellation" - ENC for David Clark) is frankly amazing for a headset this lightweight. The Telex D50 is probably the quietest headset on the market, claiming a 50 dB active noise reduction. Plus the Telex has excellent passive reduction. Nevertheless, switching back and forth between the two headsets, I could barely tell the difference between them with the ANR switched on.
Music and audio. Playing music through the Bluetooth connection to my Android smartphone was crisp and clear. As advertised, audio was muted whenever the COMM was receiving. As far as I could tell, the muting of the audio was immediate, with no cut-off the the earliest part of the transmission. OTOH, when the frequency quieted down, the audio slowly came back. AOPA did a good video review of the DCPro. One of the few knocks was the slow return of audio, especially when using the smartphone as telephone. That's not something I checked for. I don't anticipate using the phone except on the ground so, for me it was a simple matter of using the aircraft audio panel to switch the headset COMM feed off when I made a call. The test call was to my wife while taxiing at the end of the flight. Like the audio, loud and clear and crisp on both ends of the conversation.
One more. One feature of my Telex that never worked was the automatic shut off, so I was curious what the DCPro would do. So after shutdown, I left it on and connected as I pushed the Warrior into its space and cleaned up the cockpit. When I went to get the headset, it was indeed off.
I like it.
