I will say this... Having owned the 850 prior to the DC ProX the winner is clearly the DC’s. I couldn’t get those 850’s off my head fast enough. It had pressure points and made my dome hurt. Then again I do have an odd shaped head.

DC’s are comfy but they do require batteries, which the 850’s don’t. One draw back. However as I said before most captains opt for the lunar lander technology headset. No ANR required.
