Bose announced its latest earbuds in June , but the QuietComfort Ultra Earbuds (2nd gen) ($299) 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 debuted in 2023 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 the best option for those primarily concerned with blocking distractions, and Bose’s tweaks make its best earbuds even better.

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.
Specifically, the company updated the algorithm for its ActiveSense technology in Aware (transpancy) Mode. Now the QC Ultra Earbuds offer smoother changes in ANC levels to combat sudden spikes in ambient noise. This means things like sirens should no longer drown out your music or podcast. Unfortunately, I wasn’t able to trigger the retooled adaptive ANC with simulated police sirens from YouTube — the best option on my quiet cul-de-sac — but I’ll report back if I notice any oddities here.

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.
Thankfully, you no longer need an additional accessory for wireless charging on the QC Ultra Earbuds. With the first-gen model, you had to buy a separate cover to enable cable-free recharging. Bose has now built all of that into the case for the second-gen set, a welcome upgrade that really should’ve been here from the start. When the original QC Ultra Earbuds debuted in 2023, wireless charging was certainly already the norm.
