For my flight case I bought (ok I didnt buy it, it was a gift from my wife last year, i probably would have gone with the standard leather one but so far I enjoy this one.)

I can vouch for what everyone else says on the hearing. I use a Bose which I bought when I started my commercial and I just bought a lightspeed mach 1 which I have yet to try but have heard good things. One of the reasons for switching to the mach 1 is saving space in my flight bag as well as something a little less obtrusive on my head for the 16 hour days.
I went with the cheap luggage because I have read and heard good things about it and with a 4 year warranty I really do not have that much to lose. If it kicks the bucket then I will weigh my options.
