Amazon offers the Bose QuietComfort 25 Acoustic Noise Cancelling Headphones for iOS for $174.99 with free shipping. (Newegg and Best Buy charge the same.) That's $3 below our mention from five days ago and the lowest price we've seen for a new pair. (It's the best deal now by $4, although most retailers usually charge around $280 to $300 for these headphones.) They feature Bose Active EQ and TriPort technology, in-line remote and volume control, and folding earcups.
