Needing to get a night's sleep on an airplane a couple days ago, I got to thinking about getting some noise-cancelling headphones. I tested the Bose® QuietComfort® 3 Acoustic Noise Cancelling® Headphones yesterday, and I would have bought them impulsively, but the store — at the Apple Store in SoHo — was out of them.
So now I've got to contemplate the purchase rationally.
Pro: Sounded good. Seemed to cancel some noise. Rested softly but solidly on the ears (and no ridiculous cup around the ears).
Con: $349 is expensive. No built-in microphone-switch for the iPhone. Too big and bulky to look good walking around in outdoors.
ADDED: I think I should hold onto my money until Bose comes out with headphones that work with the iPhone. That's so important to me, and I heard they were going to do it soon.
