I have the Sony NC-10 earbuds you're talking about. I've tried the Bose, and they are very similar, but some things you should know about the NC-10's. I chose them because of the size, they are so small that I leave them in a small pocket of my bag and therefore always have them wherever I go. I like that, never remembering to pack them. They fit very snuggly in your ear canal due to their design, which fits like a very good pair of earplugs. After a number of hours, your ear canals can begin to sweat and some people find them uncomfortable, although I don't. My favorite feature is the Flight Attendant button, inline with the cord is the power switch, battery, and this button. Pressing the button mutes your music, and turns on two little microphones on the earbuds that amplify the outside noise. So when the flight attendant comes over, or your companion wants to talk to you, you press the button and have the conversation without removing your headphones. Great feature, and it doesn't come on any other pair of Sony's, only the NC-10's.

As for the price, in the Asian airports, NRT, SIN, you can pick them up for $90. If you aren't going to be in that area, then check the website www.pricescan.com under Electronics > Audio > Headphones. Someone is selling them for $125.

Edited to add, they fit very snug, are very small, and battery life is about 60 hours on one AAA battery.
