For what it's worth, I had a Sennheiser HMEC-25KAS I used flying the CRJ at work and rental C182's and C172's. It was ANR, light weight, pretty comfortable and worked well in the Cessnas as well as the CRJ. About $540 over the web. If interested, be sure to look at the KAS model, it is stereo and includes volume control that the KA model lacks. They now make a version that gets it's power for the ANR from the mic jack so no need for batteries. If you get the battery powered version, 2 AA's ran about 25-30 hours in the CRJ. It's a pretty tall order to find the 'one perfect headset.' Good luck.
