The Bose QuietComfort Ultra Earbuds (2nd Gen) are Bose's in-ear flagship: Adaptive Noise Cancelling, Aware Mode, Immersive Audio and, new for this generation, a case that charges wirelessly. Bose Canada lists them at C$379; on November 5 Bose and Amazon.ca both sold the black pair for C$299.
Bose rates six hours in Quiet or Aware mode and four with Immersive Audio. The case holds three more charges; IPX4 covers splashes, not swimming.
Our verdict
At the C$379 list price these are the Bose in-ears to buy for Adaptive ANC, Immersive Audio and wireless case charging; the C$299 seen on November 5 makes six hours per charge easier to accept.
- A good fit for
- Someone on long transit rides or frequent flights who wants Bose adaptive cancelling in an in-ear, watches films with Immersive Audio and carries the case.
- We would skip it if
- Six hours between top-ups is too short for you, you want a cable option, or you plan to swim with them; IPX4 only covers splashes.
Reasons to consider it
- ActiveSense, improved over the first generation, drives the Adaptive ANC; Aware Mode and CustomTune come with it
- Immersive Audio turns stereo into a spatial mix and trims each charge from six hours to four
- IPX4, Bluetooth 5.3, nine tip and band pairings, and a wireless-charging case with three refills
The compromises
- With six hours a charge, a cross-country flight means a stop in the case
- Running Immersive Audio leaves four hours per charge
- No cable listening and no adapter included; Bose names only the A2DP and HFP profiles, not a codec
What we have not verified: Fit, cancelling in daily use and call quality depend on the listener's ears and surroundings. Bose's six hours come from its February 2025 test at 75 dB, Quiet Mode, Immersive Audio off; higher volume or Immersive Audio means less.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Bose QuietComfort Ultra Earbuds (2nd Gen)
C$379 list, Adaptive ANC, Immersive Audio and a case that charges wirelessly.
Before you buy: Six hours per charge; IPX4 only.
Price checked November 5, 2026. Retailer prices can change.What C$379 buys
The box holds the earbuds, the charging case, a 30 cm USB-A to USB-C cable and the Bose Fit Kit; Bose states that no power adapter is included.
The Fit Kit has three eartip sizes and three stability bands, nine combinations in all.
On November 5 Amazon.ca and Bose Canada both showed C$299, 21% under the C$379 list price; neither page gave an end date.
Six hours, or four with Immersive
Bose quotes six hours in Quiet or Aware mode and four with Immersive Audio, tested at 75 dB. Three full refills sit in the case, and a 20-minute top-up buys up to two hours.
Charge the case by USB-C or on any third-party wireless pad. On a long flight the total that matters is buds plus case, not the buds alone.
Cancelling and fit
ActiveSense evens out sudden bursts of outside noise while the Adaptive ANC runs; Aware Mode lets the world back in. Bose credits the second generation with improved ActiveSense, AI call noise suppression and wireless case charging.
CustomTune tunes the sound to each ear canal. How well the tips and bands seal sets how much noise the cancelling can remove.
