Review: Bose A20 v Lightspeed PFX v Lightspeed Zulu2 v David Clark w/ANR
I have a pair of DC Pro X. I find them to be an excellent headset. They look bigger in the pictures than they really are. So, they fit nicely into any carry on bag you have.
The longest flight I have done with them is 10 hours. They were comfortable for the whole flight. Or, as comfortable as a headset can be after 10 hours.
The batteries last about 40 - 50 hours of use.
The ANR is very good with 30 db reduction. I use them in a 7X and I turn the volume control down by a half now as compared to having the ANR turned off.
I would recommend them.
