I started with the bose aviation X, which were really good. However, they're still an over-the-ear headset which I personally don't like. I've always hated the clamping feeling that they give you, whether they're bose, DC's, whatever...Soooo I sold them on ebay for $500 (bought them used from a friend from $500, so no loss there) and bought used Telex 750's on ebay (as far as I could tell they were brand new) for $70 and wear ear plugs and am very happy. There is no discomfort and you get used to wearing ear plugs so it's not a big deal at all. The one downfall is that I feel like comms can be a little muffled, but not to the point where you can't understand. Overall, if you hate the clamping feeling, go with 750's (or if you have money, clarity alofts) but if you don't care about that then go with an expensive over-the-ear headset.
