We have ANR sennheisers in our planes. I was using my A20s for a while but got tired of unplugging the ship set, plugging mine in, then replugging the ship set back in at the end of each flight, every time I flew, and I was tired of lugging around a headset. Our sennheisers aren't bad. Not worth the hassle of having my own. The headsets my regional provided in the CRJ were bad, though, and it was worth it to have my own.
