I know several people who are very happy with the Clarity Aloft for aerobatics (which is a pretty rough/noisy environment). I started to look at the JH Audio Aerous headsets, which got very good reviews, but then got a great deal on a Gentex helmet instead. For these headsets you have to get impressions of your ears made by an audiologist then send them to JH so they can custom make a unit that fits your ears. Even if you don't fancy the headsets I highly recommend reading the owner's manual, which is available for download from their website - it's hilarious.
