If you're sure you're in it for the long haul, go ahead and get yourself a good headset with ANR from day 1. Protect your hearing. The Bose seems to be the best around, but $1000 is a lot of money. I spent $300 on my Telex Echelon 150 and find that it's very good. Once I can afford it, I'll upgrade to the Bose. By that time, they'll probably have a new one out
