Note that the previous poster said "a good pair of in-ears, fitted well to your ears." He's not talking about the cheap earbuds that come with iPods.
As the owner of both a pair of Shure SE535 in-ear earphones and Bose QC15s, I'd take the Shures for noise blocking (in or out of the air) and audio quality any day of the week.
The only thing the QC15s have going for them is the price (a third the cost of the Shures) and the convenience of putting them on and taking them off (the Shures are a little convoluted to unravel and then carefully insert them into the ear canals).
