Bose QuietComfort Ultra Earbuds (2nd Gen)

Scored on 50 verified owner verdicts, from 1,151 comments read across 2 communities
TL;DR
More owners here would warn a buyer off the QC Ultra 2nd Gen than recommend it, and reliability is why. Bluetooth drops or refuses to pair on certain Android phones, a faint static or mosquito hiss sits in the left bud with ANC on, calls reach the other end muffled, eartip nozzles snap off inside a year, and the companion app fails to find the buds or shuts them down. What owners praise is not in doubt: noise cancellation many call the best they have used, a fit that stays comfortable all day and locked in during workouts, and rich, bass-forward sound. The divide is between people whose pair works and people whose pair does not.

34% of 50 verified owners recommend the Bose QuietComfort Ultra Earbuds (2nd Gen), based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube is shown for perspective but kept out here — hover the i for why.

What owners like
  • Noise cancellation is best-in-class, making flights, gyms, vacuums, and noisy stores go nearly silent · 20 · 40%
  • Fit is extremely comfortable for all-day wear and the eartips/wings stay locked in during workouts · 6 · 12%
  • Sound quality is rich with punchy, deep bass that owners rate above AirPods Pro and similar Sony models · 6 · 12%
  • Mic and call quality feel clearly improved after the latest firmware update, with natural-sounding voice pickup · 4 · 8%
What owners flag
  • Bluetooth connectivity is unreliable: slow pairing, random disconnects, and buds that won't reconnect on phones like the Galaxy S25 and Z Flip7 · 9 · 18%
  • A faint static, hiss, or high-pitched "mosquito" sound shows up in the left earbud, especially with ANC on · 7 · 14%
  • Call and mic quality can be muffled or noisy, with people on the other end struggling to hear the caller clearly · 7 · 14%
  • Buds break down over time, including the silicone eartip nozzle/collar snapping off within a year of use · 5 · 10%
  • The Bose companion app is buggy, failing to detect the earbuds or causing them to shut down unexpectedly · 5 · 10%
Who it's for
A great fit if
  • Frequent flyers wanting best-in-class noise cancellation
  • Gym-goers needing a secure, comfortable all-day fit
  • Bass fans who like an immersive, punchy sound
  • Commuters silencing crowds, restaurants and offices
Look elsewhere if
  • People needing rock-solid Bluetooth after firmware updates
  • Listeners bothered by faint hiss they can't fully disable
  • Those who take frequent calls in noisy environments
