I am still in "musical headset" hell......
First I had a pair of DC 13.4's. They gave me headaches.
Then I bought Lightspeed 20XL2's. They gave me headaches.
Then I bought Lightspeeds first in-the-ear set (Light Flight?). They sucked, never made it in an airplane they hurt my ears so bad with the square portion that is supposed to fit comfortably in your ear.
Then I bought Clarity's. Pretty great headset. The minuses for me are no audio input, no ANR and a recurring cost of $25 for new canal tips when old ones wear out (the manual says use a new set every 5 flights, you get 6 pair per package). I still have the Clarity's, but jumped on the Bose wagon today.
I am pretty pissed about the Bose set because I feel that in paying $1000 I should get an audio input from one of the leading speaker manufacturers in the world. Also, the volume controls move on a whim like the lightspeeds, and they aren't marked so you can tell before you plug them in and fire up comm's. I haven't tried the Bose in flight yet because I'm afraid the sound quality will make me become masochistic over the volume controls. I had a hell of a time with those on the Lightspeed set. The difference between the two is that the Lightspeeds could clearly be adjusted before blowing your ear drums through the other side of your head.
Next on my list will be the Telex Stratus 50D, if I decide to ship the Bose back. The Telex's have an instructor rebate that brings the price down to just over $500. I have tried a pair on and they clamp a little bit for me. I will have to do some research on adjustability of the headband or other items to make them a little wider for my melon head. The great thing about this set is that it has everything else that I am looking for. They also have a cigarette adapter if it is available in the aircraft to bypass battery usage.
As many pairs of headsets that I have had, I should write a thorough How-to, or better yet How-Not-to. The chief charter pilot made me laugh today a little bit when he told me to calm down, there is no perfect headset. Well damn it, I want one.
