Bose QuietComfort Ultra Earbuds Review: The ANC Benchmark
- Brand:
- Bose
- Ages:
- 13+ years
- Updated:

The verdict
The QC Ultra Earbuds deliver the noise cancellation and immersive sound Bose promises, but they ask you to accept genuinely mediocre battery life in exchange — worth it if ANC quality is non-negotiable, frustrating if you need a full day away from a charger.
Pros
- Widely regarded as having some of the best measured active noise cancellation of any earbuds on the market, adjustable in strength via the app
- Immersive Audio spatial sound mode genuinely widens the soundstage for music and movies, not just a gimmick toggle
- Stability band ear tip option keeps the fit secure during movement without needing a separate sport model
- Strong, natural call quality thanks to Bose's microphone tuning
Cons
- Battery life is the weak point of the lineup — about 6 hours per charge with Immersive Audio off, dropping to roughly 4 hours with it on
- At $299 list price, it competes directly with Sony and Apple's flagships without a battery-life advantage
- The charging case only adds about three extra charges, so total runtime trails cheaper earbuds by a wide margin
- No meaningful battery improvement over the previous QuietComfort Earbuds II generation
This review is based on Bose's published specifications and the consistent consensus across independent audio reviews and long-term owner reports since launch, weighing the QC Ultra Earbuds' strengths against its most commonly cited weakness.
Noise cancellation that lives up to the name
Bose has built its reputation on ANC for over a decade, and the QuietComfort Ultra Earbuds carry that forward — independent lab measurements consistently place them among the top performers for cancelling both low-frequency rumble and higher-pitched noise, with adjustable strength levels in the Bose app for situations where full cancellation feels too isolating.
The battery life trade-off
This is the one spec where the QC Ultra Earbuds fall behind rivals: roughly 6 hours per charge with the standout Immersive Audio spatial feature switched off, and noticeably less with it on. Reviewers are consistent on this point — it's the main reason to hesitate before buying, not a one-off complaint.
Who it's for
Best for listeners who treat noise cancellation as the deciding factor and who can live with topping up the case during the day. Skip it if all-day battery life without recharging is your top priority — look at Sennheiser or Anker's alternatives instead.
Frequently asked
- How long does the battery actually last?
- Bose rates it at up to 6 hours per charge with Immersive Audio off, and roughly 4 hours with it on, which is shorter than most competing premium earbuds. The case adds about three additional charges.
- What is Immersive Audio mode?
- It's Bose's spatial audio feature that widens the perceived soundstage for music and movies, making sound feel less like it's coming from inside your ear. It sounds noticeably different but does reduce battery life when active.
- Are these better than the regular QuietComfort Earbuds II?
- The Ultra model adds Immersive Audio and a slightly refined design, but core ANC performance and battery life are very similar to the previous QuietComfort Earbuds II.
- Is the Bose QuietComfort Ultra Earbuds worth buying?
- Yes, if you want some of the best noise cancellation available and can tolerate recharging mid-day. If long battery life matters more to you than peak ANC performance, it's worth comparing against Sennheiser's or Anker's flagship earbuds first.
