In designing its fourth-generation consumer noise-canceling headphones, the QuietComfort 15s, Bose has done something interesting. Instead of coming up with a whole new look for its headphones as it did with the QuietComfort 3s, Bose has left the basic design of its popular QuietComfort 2s intact and simply redesigned them on the inside, adding even more effective noise-canceling circuitry and improving their sound quality.
The QuietComfort 15s look identical to the QuietComfort 2s, with the same over-the-ear design, including earcups that swivel and fold flat to fit in a stylish case. (To be clear: the QC15s replace the QC2s, which will no longer be sold.) Bose has redesigned the case so it's easier to plop the headphones in it and close it up. The resulting package is slightly bigger than a CD wallet, which makes it easier to tote, though it's still not terribly compact.
