Bose announced its latest earbuds , but the won’t arrive until early September. Today, though, they’re available for preorder, and I’ve spent the last few weeks testing all the new features. This model is an overhaul of the noise-canceling earbuds the company alongside its take on spatial audio. Among the upgrades, Bose has improved the active noise cancellation (ANC) performance, enhanced call quality and added wireless charging to the case. Two years later, the QuietComfort Ultra is still for those primarily concerned with blocking distractions, and Bose’s tweaks make its best earbuds even better.
The best noise-cancelling earbuds are further improved thanks to enhanced ANC and other upgrades.
- Stronger ANC filters out more distractions
- Enhanced call quality
- Battery life isn’t improved
- Bulky design is unchanged
What’s new on the QuietComfort Ultra Earbuds (2nd gen)?
The new QC Ultra Earbuds are at their best in Quiet mode. This is Bose’s option for full noise cancellation without spatial audio (or Immersive Audio, as the company calls it). Here, there’s no doubt these are still the best noise-cancelling earbuds available right now. The first-gen version achieved the same feat, but Bose has gone a step further to enhance its ANC setup for this refresh.

Bose also upgraded call quality on the QC Ultra Earbuds. The company says a new AI-powered setup, known as SpeechClarity, works with “the earbuds’ eight microphones, dynamic mixing and adaptive filters” to focus on your voice. Bose explains that it uses audio augmentation tech that was originally developed for hearing aids here, which can reduce background noise like wind or the drone of an office. During my tests, the revised system silenced a noisy fan, rendering it completely absent from my recordings. However, overall voice quality suffers as you will sound a bit staticky when all the audio processing kicks in.
