[quote=“Mother Theresa”]Seems clear the unanimous winner is Bose, but at US$300-400 for a pair, they won’t be getting my business. So I’m considering these instead (primarily for long flights):
Sony MDR-NC6 Noise Canceling Headphones

At Amazon.com they’re marked down from $79.99 to $35.99 and they get fairly good reviews.
Has anyone tried those headphones or any other noise-cancelling headphones?[/quote]
I have a pair (NT$2100 from Guanghua Market), and they’re good at shutting out background noise. But the main disadvantages are: air blowing on the microphones causes annoying noise so they can be a bother to wear outside on a windy day, and they can be pretty hot to wear in the summer.
