The Good Extracomfortable design; improved sound; highly effective noise-canceling circuitry; device folds for compact storage in included carrying case; 30-day home trial.
The Bad Expensive; when the battery dies, so does the music.
The Bottom Line While they're no bargain, the Bose QuietComfort 15s currently offer the best sound and silencing capabilities in a pair of noise-canceling headphones.
Bose Quiet Comfort 15
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 that 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. As you'd expect from a set of headphones designed for frequent travelers, Bose throws in a two-prong airline adapter. The 'phones also offer a "high/low" switch, which should prevent your ears getting blasted when the pilot or flight attendant comes over the PA system.
As we said about the QuietComfort 2s, even without the noise-canceling engaged, the earcups' deliciously soft cushions effectively sealed off our ears from the noisy environment. While the QuietComfort 2s only had noise-canceling microphones (for detecting the ambient noise) on the inside of the earcups, the QC15s have them on the inside and outside, which is said to increase their effectiveness. Flipping on the noise cancellation--which pumps out "anti-noise" to proactively counteract the environmental sounds--damps down the noise even further.
