What reviewers say

Bose QuietComfort Ultra Headphones

  • Noise cancellingPraisedOwners say ANC blocks out background noise superbly and ActiveSense smooths sudden spikes.

Questions and answers

Which has better noise cancelling, the Bose QuietComfort Ultra or the Anker Space Q45?
The Bose. Its ANC is widely rated among the best, with CustomTune adjusting to your ears. The Q45 blocks a lot for its class but does not match it.
Which lasts longer on a charge?
The Anker Space Q45, by a wide margin: 50 hours with ANC on versus 24 for the Bose. The Q45 also gives 4 hours from a 5-minute charge.
Is the Bose worth stepping up to over the Q45?
Yes if noise cancelling, spatial audio and comfort matter most. If battery life, a wired jack and LDAC matter more, the Q45 covers them.
Can I use either one wired?
The Q45 has a 3.5 mm jack, so it works with no battery. The Bose is USB-C and Bluetooth only.
Which is better for flights?
The Bose for blocking engine noise; the Q45 for long-haul trips where you cannot recharge often.
Do either handle rain or sweat?
Neither is rated water resistant. Treat both as dry-weather headphones.
