I have a Peltor and a David Clark, both used in professional aviation in very high noise environment. Peltor very light and comfortable much more robust than they look. I only wear the David Clark's because that is what the intercom system on the particular aircraft type will accept (apart from the Bose X which were found to be no better than the DCs). Otherwise, they are too heavy.
But be aware, the best headset will depend on the type of aircraft you are flying. It is hard to fault the Peltor, especially if you combine them with ear plugs. I would love to try the in ear types - on paper at least they seem to be the way to go.
