or if you are expecting rapid progression onto twins - something with ANR.
Not to be rude, but the time you want an ANR headset is in a single. It's much noiser with a donk in front of you than on the wings behind you (especially in a 210)
(unless it's garretts on the wing behind you pumping)
I never used ANR flying a twin, but I have heard that it's easier to let the props go out of sync without correcting them.
