Fry's Electronics offers the Bose QuietComfort 20i Acoustic Noise Cancelling Headphones, model no. 362544-0010, for $249 with free shipping. (Amazon charges the same, as do B&H and Nordstrom.) That's the lowest total price we could find by a buck, although many stores charge over $290. (However, we saw them for $5 less in March.) Designed for iOS devices, they feature active noise-cancelling technology, a foldable design, built-in mic with remote, and inline volume control.
