The Bose QuietComfort 25 are the latest in their long line of excellent noise cancelling headphones. Featuring a new design, updated electronics, and some new features, the QC25s seem, on paper, to be a solid development from the old QuietComfort 15s. Another small but significant change is the shape of the headband. Bose has re-engineered it to sit closer to the head, so there’s less of a gap under the headband. QuietComfort 25 is available in the US and a few countries. The Shop2Ship tax-free price starts at $150 while Shop2Ship international shipping starts at $20 to worldwide destinations.
