Thanks for all the helpful replies guys. Turns out that last night I did in fact go ahead and order the Oregon Aero enhancement kit for my 13.4's. It gets pretty rave reviews and I like the fact that I can build up from an entry level headset and not have to drop a grand on a 'Zulu or a Bose this early in my flying "career". At least, I HOPE it is the beginning of a flying career!!!
