Editorial Summary
The Bose QuietComfort Ultra Earbuds 2nd Gen are a focused refinement of Bose’s premium true wireless earbuds rather than a full redesign. The core promise is simple: stronger everyday quiet, cleaner calls, wireless charging, secure comfort, and a more polished feature set for people who care about active noise cancellation above almost everything else.
They are not the smallest earbuds. They are not the longest-lasting earbuds. They are not the most customizable earbuds for serious EQ tweakers. But they are among the most convincing premium ANC earbuds for frequent travelers, commuters, office workers, and anyone who wants a reliable escape from surrounding noise.
Final Score: 8.7/10
Verdict: A premium ANC benchmark with meaningful refinements, held back mainly by average battery life and a still-bulky design.

What Changed in the 2nd Gen Model
The 2nd Gen update is not about dramatic visual change. Bose kept the familiar QuietComfort Ultra Earbuds design and focused on practical improvements that matter in everyday use.
The most important changes are:
- Wireless charging support built into the case
- Improved adaptive noise cancellation through updated ActiveSense behavior
- Clearer call handling with AI-assisted background-noise suppression
- Bluetooth multipoint for connecting two devices at once
- Case battery reporting in the Bose app
- Option to disable touch controls through the app
This is a refinement cycle, not a reinvention cycle. That matters because some buyers may expect a smaller shell, longer battery life, or a radically new acoustic platform. Those are not the story here. The story is smoother daily usability and stronger confidence in Bose’s already-established ANC identity.
Design and Build Quality
A Familiar Shape With a Practical Fit System
The earbuds still look and feel like Bose’s recent premium in-ear models. They are larger than many rivals, but Bose offsets that size with a strong fit system. The included ear tips and stability bands allow multiple combinations, which helps more users find a secure seal.
That secure seal matters. With ANC earbuds, fit is not just about comfort. It also affects bass response, passive isolation, and how effectively active noise cancellation can work.
Comfort Over Long Sessions
For most users, comfort should be strong. The stability bands reduce the feeling that the earbuds might loosen while walking, commuting, or working at a desk. However, the larger body can create pressure during long sessions, especially for users with smaller ears.
These are comfortable premium earbuds, but not invisible earbuds. You will likely feel them after a few hours.
Case Design
The case now supports wireless charging, which fixes one of the more obvious omissions from the earlier model. The trade-off is size. The case is useful and protective, but it is not as pocket-friendly as smaller competitors.
If you carry earbuds in a jacket, backpack, sling, or travel pouch, the size is manageable. If you want the smallest jeans-pocket case possible, this design is less ideal.
Noise Cancellation Performance
The Main Reason to Choose Bose
The Bose QuietComfort Ultra Earbuds 2nd Gen are built around active noise cancellation. This is where they feel most confident.
Low-frequency noise is handled especially well. Plane engines, train rumble, traffic hum, ventilation systems, and office background noise are the types of distractions these earbuds are designed to reduce. They also perform strongly in mixed environments where noise changes quickly, such as stations, cafes, airports, and busy streets.
Aware Mode and Adaptive Noise Control
Aware Mode allows outside sound in when you need environmental awareness. The improved ActiveSense behavior helps manage sudden noise spikes more smoothly, reducing the harshness of unexpected sounds without making transparency mode feel completely artificial.
This is useful when walking outdoors, waiting for announcements, or moving between quiet and noisy spaces.
ANC Verdict
The ANC performance is the product’s strongest advantage. Buyers who want the quietest possible earbud experience should put these near the top of their shortlist.
ANC Score: 9.7/10
Sound Quality
Bose’s Tuning: Full, Smooth, and Energetic
The sound profile is polished and consumer-friendly. Bass has weight, vocals are clear, and the overall presentation feels spacious. This tuning works well for pop, hip-hop, electronic, podcasts, movie watching, and general streaming.
The earbuds do not aim for strict studio neutrality. Listeners who prefer a flatter, more analytical sound may prefer Sony, Technics, Sennheiser, or other audiophile-leaning alternatives.
Immersive Audio
Bose Immersive Audio can make music and video feel wider. It is especially interesting for movie watching or casual listening when you want a more open presentation.
The trade-off is battery life. With Immersive Audio enabled, playback can drop from up to 6 hours to up to 4 hours. That makes it a feature worth using selectively rather than leaving on all the time.
EQ and Personalization
The Bose app gives users basic EQ control. It is enough for simple adjustments, but it is not as deep as the EQ systems offered by some competitors. If you want detailed frequency-level tuning, these may feel limited.
Sound Verdict
The Bose QuietComfort Ultra Earbuds 2nd Gen sound premium, powerful, and easy to enjoy. They are not the most neutral option, but they are tuned well for mainstream listening.
Sound Score: 8.6/10
Call Quality and Microphone Performance
Clearer Calls Than Before
Call quality is one of the more meaningful improvements in the 2nd Gen model. Bose added stronger background-noise suppression to help your voice come through more clearly in public spaces.
This matters for hybrid workers, commuters, and anyone who takes calls outside a quiet room. The earbuds are better suited to real-world calling than the previous generation.
Still Not a Dedicated Business Headset
Even with the improvement, these are still true wireless earbuds. A proper boom-mic headset will usually perform better for long business calls, webinars, or noisy work environments.
For everyday calls, quick meetings, and travel use, the call performance is strong.
Call Quality Score: 8.4/10
Battery Life and Charging
Good Enough, But Not Class-Leading
Battery life is one of the clearest limitations. Bose rates the earbuds for up to 6 hours per charge with Immersive Audio off and up to 4 hours with Immersive Audio on. The case provides up to three additional full charges.
That is acceptable for commuting, gym sessions, focused work blocks, and flights. It is less impressive for users who want a full uninterrupted workday from the earbuds alone.
Wireless Charging Fixes a Real Convenience Gap
The addition of wireless charging is welcome. It makes the product feel more aligned with premium expectations and reduces cable friction for users who already use wireless charging pads.
Quick Charging
A short charge can provide useful emergency playback time. This helps reduce the impact of the average battery rating, but it does not fully solve the limitation for heavy users.
Battery Score: 7.4/10
Connectivity and App Experience
Bluetooth 5.3 and Multipoint
Bluetooth 5.3 gives the earbuds a modern connectivity foundation. Multipoint support is especially useful because it allows users to stay connected to two devices, such as a laptop and phone.
This is a major quality-of-life feature for remote workers and students.
Bose App Controls
The Bose app handles listening modes, EQ, firmware updates, battery visibility, shortcuts, and control customization. The ability to disable touch controls is a small but important improvement for users who accidentally trigger commands while adjusting the earbuds.
Codec Considerations
The earbuds are best matched with modern devices that can take advantage of their supported Bluetooth features. Apple users will still get a polished experience, but some advanced codec benefits are more relevant to compatible Android devices.
App and Connectivity Score: 8.5/10
Durability and Water Resistance
The earbuds carry an IPX4 water-resistance rating. That means they are suitable for sweat and light splashes, but they are not waterproof.
They should be fine for:
- Walking
- Commuting
- Light workouts
- Desk use
- Travel
- Casual outdoor listening
They are less ideal for:
- Heavy rain
- Swimming
- Water sports
- High-sweat endurance training
- Dusty outdoor work where dust protection matters
For serious fitness users, earbuds with stronger water and dust resistance may be a better choice.
Value for Money
Premium Price, Premium ANC
At $299 MSRP, the Bose QuietComfort Ultra Earbuds 2nd Gen sit firmly in the premium category. That price makes sense if noise cancellation is your top priority. It is harder to justify if you mainly want long battery life, a compact case, or detailed EQ control.
The value equation improves when the earbuds are discounted. Because premium earbuds often move between MSRP and sale pricing, buyers should compare current offers before purchasing.
Best Value Scenario
These earbuds deliver their best value when bought by someone who will use the ANC daily. If you travel often, work in noisy spaces, or need quiet during commutes, the value is easier to feel.
Weakest Value Scenario
They are less compelling for casual listeners who mostly use earbuds at home, listen for short sessions, or rarely activate ANC.
Value Score: 8.1/10
Comparison With Key Alternatives
| Earbuds | Best For | Strength | Trade-Off |
| Bose QuietComfort Ultra Earbuds 2nd Gen | Best ANC priority | Excellent noise cancellation and secure fit | Average battery, larger case |
| Apple AirPods Pro | Apple ecosystem users | Seamless iPhone integration and compact case | Less flexible for Android users |
| Sony WF-1000XM5 | Balanced sound and features | Strong sound quality and customization | Bose has the stronger ANC identity |
| Technics EAH-AZ100 | Productivity and multipoint users | Strong feature depth and connectivity | Less iconic ANC positioning |
| Samsung Galaxy Buds Pro Series | Samsung phone users | Ecosystem features and compact design | Best experience tied to Samsung devices |
Bose vs Apple
Choose Bose if you want the strongest quiet-first experience. Choose AirPods Pro if you live inside the Apple ecosystem and want the most seamless device switching, compact case experience, and iOS-native features.
Bose vs Sony
Choose Bose for ANC-first travel use. Choose Sony if you want stronger manual sound customization and a more balanced all-rounder profile.
Bose vs Budget ANC Earbuds
Budget ANC earbuds can be very good now, but Bose still feels more refined in adaptive noise control, fit stability, and premium ANC performance. The price gap is real, so the decision depends on how much quiet matters in your daily routine.
Sustainability and Repairability
What Bose Discloses
Bose identifies the main product materials as plastic, silicone, and metal. The product also includes standard recycling guidance for electronic waste.
What Remains Unclear
There is limited public detail around recycled material content, battery replacement options, repairability, and long-term parts availability for this specific model. That does not mean the product is unsustainable, but it does mean buyers should be cautious about assuming stronger eco-credentials than Bose explicitly provides.
Eco-Conscious Buying Note
The most sustainable way to approach premium earbuds is to buy a model you will keep and use for several years. In that sense, strong comfort, reliable ANC, firmware support, and durable daily usefulness matter.
Sustainability Transparency Score: 6.7/10
Trust and Safety Notes
The earbuds include common wireless product compliance and safety documentation. Their IPX4 rating should be understood accurately: splash resistance is not waterproofing.
For safe use:
- Use Aware Mode outdoors when awareness matters.
- Avoid high volume for long listening sessions.
- Do not use the earbuds in situations where full environmental awareness is required.
- Dry the earbuds before placing them back into the charging case after sweat exposure.
- Avoid exposing the case to water, because charging cases are usually less protected than earbuds.
Real-World Use Cases
Travel
This is the strongest use case. The ANC is well suited to flights, trains, airports, hotels, and city transit.
Office Focus
Excellent for blocking background conversations, HVAC noise, and open-office distraction. Multipoint also helps when moving between phone and laptop.
Remote Work
Good for casual meetings and calls. Users who spend all day on calls may still prefer a dedicated headset.
Gym and Fitness
Usable for light workouts, but not the best choice for intense training. The fit is secure, but IPX4 is not rugged enough for every fitness environment.
Movies and Streaming
Immersive Audio can make video feel more spacious, though users should expect reduced battery life when using it.

FAQ
Are the Bose QuietComfort Ultra Earbuds 2nd Gen worth it?
Yes, if active noise cancellation is your top priority. They are especially worthwhile for travelers, commuters, and people who work in noisy environments. If you mainly want long battery life or a tiny case, alternatives may offer better value.
How long does the battery last?
The earbuds are rated for up to 6 hours per charge with Immersive Audio off and up to 4 hours with Immersive Audio on. The charging case provides up to three additional charges.
Do they support wireless charging?
Yes. The 2nd Gen charging case supports wireless charging as well as USB-C charging.
Are they waterproof?
No. The earbuds are IPX4 water resistant, which means they can handle sweat and light splashes. They are not designed for swimming or submersion.
Do they support Bluetooth multipoint?
Yes. Multipoint support allows the earbuds to connect to two devices at once, such as a phone and laptop.
Should first-gen owners upgrade?
Not necessarily. If your first-gen Bose QuietComfort Ultra Earbuds still work well and you do not need wireless charging, improved calls, or updated adaptive ANC behavior, the upgrade may feel modest.
Final Verdict
The Bose QuietComfort Ultra Earbuds 2nd Gen are not built to surprise people with a radical redesign. They are built to make an already strong ANC earbud more complete.
The biggest wins are practical: wireless charging, improved call performance, strong adaptive noise cancellation, secure comfort, multipoint, and a polished app experience. The biggest weaknesses are equally clear: average battery life, a bulky case, limited ruggedness, and only moderate sound customization.
For buyers who want the quietest, most focused true wireless experience in a premium package, these are easy to recommend. For buyers who value battery life, compact design, or ecosystem features above ANC, the competition deserves a close look.
Final Recommendation: Buy the Bose QuietComfort Ultra Earbuds 2nd Gen if premium noise cancellation is your daily need, not just an occasional feature.
