Bose QuietComfort Ultra Earbuds (2nd Gen) Review 2026: Silence, Perfected

The short answer

The Bose QuietComfort Ultra Earbuds (2nd Gen) are the current-generation flagship in-ear ANC earbuds from Bose, priced at $299. If your number-one priority is shutting out the world — jet engines, subway screech, open-office chatter — independent reviewers consistently rank Bose’s noise cancellation as the best you can get in an earbud, and the Gen 2 adds Snapdragon Sound (aptX Lossless and aptX Adaptive), wireless charging, and improved call quality over the original. The September 2025 update is iterative rather than revolutionary, but it fixed the first generation’s most glaring gaps.

What you don’t get: class-leading battery life (6 hours with ANC, 4 with Immersive Audio on), the smallest case, or the most exciting sound signature out of the box — Bose’s default tuning is bass-forward, though the app EQ fixes that. At $299 they’re the priciest of the big three flagships, but for travelers and commuters, the ANC alone justifies it. Think of these as the specialist’s choice: they do one thing — silence — better than anything else in their form factor.

It’s worth understanding what “2nd Gen” means here. Unlike a ground-up redesign, Bose kept the same bud shape, the same CustomTune ANC hardware, and the same battery life, then modernized everything around it: the Qualcomm S5 platform, the wireless-charging case, the mic system, and the codec stack. If you own the first gen, that’s an incremental upgrade; if you’re buying fresh in 2026, it means you’re getting the finished, fixed version of Bose’s flagship vision.

This is a research-based review. We have not tested the Bose QuietComfort Ultra Earbuds (2nd Gen) hands-on; every fact below comes from the manufacturer’s published specs, pricing, and independent reporting. Prices and specs checked September 30, 2026.

Key specs

Price and availability

Bose sells the QuietComfort Ultra Earbuds (2nd Gen) for $299 — the same launch price as the first generation. They launched in September 2025 and are widely available from Bose.com, Amazon, and Best Buy in Black, White Smoke, Deep Plum, and Midnight Violet. Holiday sales occasionally knock them to ~$249; they’re rarely discounted as steeply as Sony’s flagships, which tend to see deeper and more frequent cuts.

Don’t confuse them with the original QC Ultra Earbuds (2023), which sometimes appear at clearance prices around $199. The Gen 2’s wireless-charging case, aptX Lossless support, and improved mics make it worth the premium over leftover first-gen stock — the original’s SBC/AAC-only codec support is a real limitation in 2026. Bose also offers BoseCare accident-protection plans at checkout, worth considering given the $299 price and the buds’ larger-than-average size.

What it’s good at

• Best ANC in any earbud: Reviewers across the board — Tom’s Guide, Android Central, and lab-style testing — rank Bose’s CustomTune ANC as the industry leader for in-ear silence. CustomTune plays a test tone and calibrates cancellation to your specific ear shape every time you insert them. Low-frequency rumble (planes, trains, HVAC) essentially disappears.
• Comfortable, secure fit: The stability bands plus three tip sizes keep the buds locked in for most ear shapes, and reviewers note the Bose fit is more universally comfortable than Sony’s foam tips — no expanding foam pressing against your ear canal.
• Big codec upgrade in Gen 2: Snapdragon Sound brings aptX Adaptive and aptX Lossless on Android — a real fix for the first gen’s SBC/AAC-only limitation, and it makes these legitimate hi-res wireless earbuds for the first time.
• Strong call quality: The improved mic system with background-noise rejection earns high marks for voice calls, a traditional Bose strength — your voice comes through clearly while street noise fades.
• Wireless charging and multipoint: The Gen 2 case finally charges wirelessly on any Qi pad, and multipoint pairing to two devices (say, a work laptop and a personal phone) works reliably with sensible switching behavior.
• Customizable modes: The Bose app lets you dial ANC levels from full to transparency in fine steps and build activity-specific modes (running, office, commute), plus Immersive Audio with Still/Motion settings for spatial sound that tracks how you move.

Where it falls short

• Average battery life: 6 hours with ANC (4 with Immersive Audio) trails Sony (8h) and Google (8h); the case adds only ~18 more hours for a 24-hour total. Long-haul travelers will be reaching for the case while Sony owners keep listening.
• Bulky case and dated-looking buds: The design is unchanged from the first gen — the buds are large with a distinctive earpiece look, and the case is chunky next to Apple’s or Google’s pocket-friendly designs.
• aptX Lossless needs Android: iPhone users get AAC only, blunting the Gen 2’s headline audio upgrade. They’re still excellent on iOS for ANC and calls, just not using their full audio potential.
• Most expensive of the trio: At $299, they’re $50 more than AirPods Pro 2 and often $20+ more than discounted Sonys — and Bose discounts are shallower, so the gap persists.

Who should buy it

Frequent flyers, daily commuters, and open-office workers for whom maximum noise cancellation is the entire point. If you wear earbuds primarily to create silence — and you value comfort and call clarity alongside it — nothing in-ear beats these. Android users additionally benefit from the aptX Lossless upgrade, and the multipoint support makes them a strong work-from-anywhere companion.

Who should skip it

Battery-anxious listeners (Sony and Google last longer per charge), audiophiles who want the most natural out-of-box tuning (Sony and Sennheiser edge Bose on fidelity — though the EQ helps), and iPhone users paying full price when AirPods Pro 2/3 deliver a more integrated experience for less. Athletes wanting a slim, sweat-proof fit should look at sport-specific buds instead.

Verdict

4.6 / 5 — The undisputed ANC champion in earbud form, now with the wireless charging and codec support the first gen lacked. Average battery and a premium price are the only real knocks, and neither matters much if silence is what you’re buying. For the specific job of making the world go quiet, nothing else in this roundup comes close.

FAQ

What’s new in the 2nd Gen versus the original QC Ultra Earbuds?

A Qualcomm Snapdragon Sound platform (aptX Adaptive/Lossless), a wireless-charging case, improved microphones for calls, and new color options (Deep Plum, Midnight Violet, White Smoke). The design, ANC hardware, and battery life are essentially unchanged — it’s a refinement, not a redesign.

How long does the battery last with Immersive Audio on?

About 4 hours per charge, versus 6 with standard ANC. The case brings total listening to roughly 24 hours. If you use Immersive Audio constantly, expect to charge more often — it’s the biggest battery drain in the feature set.

Do they work well with iPhone?

Yes for ANC, comfort, and calls — but aptX Lossless is Android-only, so iPhone users listen over AAC. They’re still excellent on iOS, just not using their full audio potential. The Bose Music app is fully featured on both platforms.

Are they good for running?

The stability bands keep them secure and there’s an IPX4 splash rating, but they’re bulky and expensive for the gym. Fine for occasional runs; dedicated sport buds fit better, cost less, and survive sweat more gracefully.
