Looks as though I'll be doing a lot more travelling for my job in 2006, and I'm thinking of getting something a little nicer than the standard earbuds that come stock with the iPod. The Bose QC Noisecancelling look interesting, if only for the fact that they claim to reduce outside noise. But they seem large (even though they fold-up for storage) and rather pricey. Bose Ultimately I'd like something that doesn't take up a lot of room in my carry-on bag and reduces outside noise, but aren't so huge that I look like I should be sitting in the cockpit with the pilot. Not sure if I should be looking at enclosed or earbuds. I will really only be using these on the plane/in the airport - not at home, working out, etc. Frequent fliers - what do you use? Any suggestions? Thanks in advance!
