If a lightspeed isn't comfortable, have you tried the Bose A20?
I would say the Sennheiser ANR sets aren't bad, but since I got my A20 I wouldn't touch one.
Basically, it's your hearing you need to value, more than comfort. As I say to the young F/Os I fly with, if you want to hear the giggles of your grandchildren when you are old, invest now!
