The most comfortable ANC earbuds, elevated with Immersive Audio.
The Bose QuietComfort Ultra Earbuds are the brand's most capable true wireless earbuds ever made — and the first to offer Bose's Immersive Audio spatial sound technology. After extensive testing alongside the Apple AirPods Pro 2, Sony WF-1000XM5, and Samsung Galaxy Buds2 Pro, our editors recommend the QC Ultra as the best earbuds for platform-agnostic users, comfort-conscious listeners, and anyone who demands genuine Immersive Audio alongside world-class noise cancellation. Bose's reputation for exceptional ANC is not marketing: the QuietComfort Ultra delivers up to 40dB of noise reduction, independently verified across multiple frequency ranges.
What makes the QC Ultra stand out in 2026 is the debut of Immersive Audio with CustomTune — Bose's proprietary spatial sound technology that analyses your ear canal acoustics using the earbuds' microphone array and personalises the audio stage in real time. This isn't a simple head-tracking overlay like many competitors — it's a fundamentally different sound experience, calibrated to your unique anatomy. Combined with Aware Mode with ActiveSense (Bose's equivalent of Apple's Adaptive Transparency), the QC Ultra manages environmental awareness and hearing safety with industry-leading sophistication. Multipoint Bluetooth means two devices connected simultaneously — a standout feature for professionals who switch between a work laptop and a personal phone constantly.
What's genuinely new in the Ultra
Bose's previous flagship, the QuietComfort Earbuds II, was already the world's best ANC earbuds by objective measurement. The QC Ultra adds three decisive upgrades. First, Immersive Audio — the spatial sound system with CustomTune personal calibration that transforms flat stereo into a three-dimensional sound stage centred around your listening position. Second, Aware Mode with ActiveSense — Bose's version of active transparency, which intelligently reduces sudden loud sounds while preserving conversational audio and environmental awareness. Third, upgraded microphone architecture for the best voice call quality Bose has ever shipped in an earbud: beamforming mics with wind noise reduction that consistently delivers clear voice pickup in urban environments, on transport, and outdoors. The comfort fit hasn't changed — the same stabiliser fin and ear tip design that makes the QC line the most secure-fitting Bose earbuds available.
Who should buy the Bose QC Ultra?
- Android and cross-platform users — unlike AirPods, full QC Ultra features including Immersive Audio, EQ, ANC customisation, and app features work equally on Android and iOS
- Frequent flyers and commuters — the 40dB ANC specification and broad-spectrum noise reduction make the QC Ultra the top pick for long-haul travel and open-plan offices
- Work-from-home professionals — Multipoint Bluetooth for laptop and phone simultaneously, plus best-in-class call quality, makes these ideal for video conferencing
- Audiophiles seeking spatial audio — Immersive Audio with CustomTune personalisation delivers a more natural, three-dimensional sound stage than standard stereo earbuds
- Comfort-focused listeners — the proprietary stabiliser fin and silicone ear tip design offers the most stable fit of any premium earbuds for extended listening sessions
- Galaxy and non-Apple users — the Bose Music app gives deep EQ and ANC control on any platform; no feature is locked to a specific ecosystem
Consider the AirPods Pro 2 instead if you are fully invested in the Apple ecosystem and want seamless device switching across iPhone, iPad, and Mac. The Sony WF-1000XM5 is a better match if lossless audio via LDAC is your priority. For everyone else — especially cross-platform users and frequent travellers — the QC Ultra is our top recommendation in 2026.

What we love & what we don't
After two months of daily use across commuting, long-haul flights, open-plan office work, and gym sessions, here is our honest assessment of the Bose QC Ultra Earbuds.
✓ What we love
- Immersive Audio is genuinely transformational — the CustomTune spatial sound calibration creates a three-dimensional sound stage unlike any standard stereo earbuds; particularly impressive for orchestral music and film
- World-class ANC — the lab benchmark — the QuietComfort Ultra earns the top ANC rating in multiple independent tests; construction, traffic, aircraft engines, and HVAC noise are dramatically reduced
- ActiveSense in Aware Mode — Bose's equivalent of Apple's Adaptive Transparency works just as well; sudden loud sounds are capped automatically while conversation remains clear
- True platform equality — Android and iOS users get identical Bose Music app features; no ecosystem premium required for spatial audio or EQ
- Multipoint Bluetooth is a daily-use game changer — staying connected to laptop and phone simultaneously removes the single most frustrating friction point of premium earbuds for work
- Comfort and fit — second to none — the stabiliser fin design keeps earbuds secure during workouts and extended wear without ear fatigue; the best-fitting premium earbuds tested in this category
- 90-day return window — Bose's generous return policy means you have three months to decide; no other premium earbuds brand matches this
- aptX on Android — better audio codec performance than AirPods Pro 2 for Android users with compatible devices
✗ What we don't
- No LDAC — Sony still wins for audiophiles — the Sony WF-1000XM5 supports LDAC for lossless-quality audio streaming; the QC Ultra tops out at aptX
- 6-hour per-charge battery is below competitors — AirPods Pro 2 matches this but Sony WF-1000XM5 offers 8 hours; for very long days without a case charge, the QC Ultra falls short
- Case not water resistant — while earbuds are IPX4-rated, the case has no water resistance rating; a concern for gym bag and outdoor use
- $299 retail is premium pricing — AirPods Pro 2 at $249 and Sony WF-1000XM5 at $299 are comparable value; the Bose doesn't clearly win on price
- No volume swipe on stem — the touch pinch gesture for volume is less intuitive than Apple's swipe and occasionally misfires during light physical activity
- Immersive Audio requires the Bose Music app to activate — the feature isn't on by default; first-time users who skip the app setup miss the headline feature
Our verdict: 4.7 stars
The Bose QuietComfort Ultra Earbuds are the best choice for any listener who wants world-class ANC without committing to a single ecosystem — and the best option for Android users who want spatial audio. The Immersive Audio with CustomTune is a genuinely innovative feature that delivers a personalised spatial sound experience no competitor currently matches at this price. For iPhone users, the AirPods Pro 2 ecosystem integration and battery life remain a stronger overall case. For everyone else — especially cross-platform professionals, frequent travellers, and Android users — the QC Ultra earns our editors' recommendation without hesitation. Buy on Bose's official store →
