I like quiet, so Bose A20's excellent Active Noise Reduction really appealed to me.

Cons:-The passive noise reduction is mediocre, leading me to conclude that OVERALL noise reduction of the Bose is better than the Pro-X.-Comfort; this is where I give this headset the biggest hit

It blocks out enough noise to operate, but it is far from ideal

Passive noise reduction is significant.

, the is some passive noise reduction, enough that it is difficult to hear the guy/gal next to you.-Head and ear cushions are good for me for 5 hours of continuous wear.-The case that comes with the headset is the standard DC case

It's comfortable, the noise cancelling works fantastic

I tried to find that sweet spot where the noise cancelling and passive would work well enough

It even has reasonable passive noise attenuation with the active noise cancelling turned off (the headset works without headset power like any regular headset) so if you don't care to have it on or the batteries are

If you're flying a different kind of aircraft and want a top notch noise cancelling light weight headset, I would still recommend these.

Good sound, good noise canceling, sturdy design

Excellent headset and perfect noise canceling

The good: Noise cancelling, comfort, microphone, battery life and features are all great and easy to use

The noise cancellIng works great and there is plenty of room to wear my sunglasses

It has good noise

It even has reasonable passive noise attenuation with the active noise cancelling turned off (the headset works without headset power like any regular headset) so if you don't care to have it on or the batteries are

With the combination of Passive and ANR noise reduction, this headset creates a very quite environment

Bluetooth works well and Noise cancellation is adequate.

Passive noise attenuating

Not the best noise canceller in the market but it is the Most comfortable one

For jet pilots, Pro-X may be better suited than Bose A20 because of comfort, and ironically A20's superior noise reduction may actually become a disadvantage in quieter cockpits (several said A20 made it hard to hear their co-pilots).DC Pro-X's construction/material quality is excellent.

I must say that customer service at DC did a good job, and I'm reviewing my comments as well.-----------------------------I take my first and positive review back, after using the DC Pro X for about 20hrs in 5 or 6 flights, a constant strong noise (like static) began in one of the speakers every time I turn on the device

High product quality, nice noise reduction, great comfort

High product quality, nice noise reduction, great comfort

The passive noise cancellation isn't quite as good as my regular over-the-ear DCs, but it's pretty good for an on-ear headset

Light, great noise reduction

The passive noise reduction that the pads offers is very significant

Good noise cancellation
