The Bose QuietComfort Ultra Earbuds are designed for listeners who care more about powerful noise cancellation, comfort, and immersive audio than having the smallest possible earbuds. The second-generation model keeps the strengths of the original while adding enhanced adaptive noise cancellation, improved voice pickup, and a wireless charging case. Bose lists up to six hours of battery life, an IPX4 water-resistance rating, and adjustable noise cancellation.
For travelers, commuters, office workers, and people who frequently listen in noisy environments, these premium earbuds remain a compelling option. The bigger question is whether their $299 price is justified when competing wireless earbuds have become increasingly capable.
What Makes the Bose QuietComfort Ultra Earbuds Stand Out?
The Bose QuietComfort Ultra Earbuds focus heavily on active noise cancellation (ANC). Bose uses CustomTune technology to personalize sound and noise-control performance according to the shape of your ears. The result is a listening experience that can be particularly effective on airplanes, trains, busy streets, and in offices.
The fit also plays an important role. Bose supplies three ear-tip sizes and three stability-band sizes, allowing users to adjust both the seal and physical security. That matters because a good seal can improve passive isolation as well as the effectiveness of electronic noise cancellation.
The second generation adds adaptive improvements rather than radically changing the design. Bose specifically highlights enhanced adaptive ANC, better voice pickup, and wireless charging as the major upgrades.
Sound and Immersive Audio
The Bose QuietComfort Ultra Earbuds have a lively sound signature with noticeable bass and treble emphasis. That presentation can work well for pop, electronic music, hip-hop, movies, and other content where energetic sound is desirable.
They also support Bose Immersive Audio, which creates a spatial presentation intended to make compatible content feel less confined to the traditional left-right earbud arrangement. It is a useful extra, although listeners who prefer a more natural or neutral presentation may not always want it enabled.
One limitation is EQ flexibility. Independent testing from SoundGuys found the default sound enjoyable for many listeners but criticized the relatively limited equalizer options for people who want detailed control over the tuning.

Battery Life, Charging, and Everyday Use
Bose rates the earbuds for up to six hours on a full charge, although actual runtime varies with volume, settings, and features. Independent testing recorded approximately 5 hours and 34 minutes under controlled conditions, illustrating why real-world battery life should not be confused with the manufacturer’s maximum figure.
The charging case is one of the more useful second-generation changes because wireless charging is included rather than requiring an additional accessory. USB-C charging remains available for conventional wired charging. Bose also says the earbuds can provide up to six hours of listening time per charge.
For a long flight or workday, the battery capacity is adequate, but these are not class leaders for endurance. Their stronger selling point is the balance between battery life and the substantial ANC feature set.
💡 Pro Tip: Spend a few minutes trying all three stability-band sizes and run the ear-tip seal test before judging the ANC. A poor seal can make otherwise excellent noise cancellation seem disappointing, while the correct fit can noticeably improve isolation and comfort.
Are They Comfortable for Long Listening?
Comfort is highly dependent on ear shape. The earbuds are relatively substantial, but the stability bands help keep them secure without relying entirely on pressure from the ear tips.
SoundGuys found the second-generation model comfortable overall, while also noting that its larger physical design may not suit people with smaller ears. The ovoid nozzle and multiple fit options can make it easier to achieve a stable seal for users whose ears accommodate the design.
That makes these earbuds especially interesting for travelers and active listeners who dislike constantly readjusting loose earbuds. However, buyers with small ears should consider fit carefully before committing to a premium purchase.
Bose QuietComfort Ultra Earbuds vs. the Original
The second-generation model is an evolutionary upgrade rather than a complete redesign. The basic philosophy, fit approach, and emphasis on ANC remain familiar.
The most meaningful additions are enhanced adaptive noise cancellation, improved voice pickup, and wireless charging. Bose also retains CustomTune personalization, which was already a central feature of the previous generation.
For someone who already owns the first-generation model, the upgrade is harder to justify at full price. SoundGuys similarly characterized the second generation as a relatively modest refresh, with improvements that are useful but not transformational.
For a new buyer, however, the decision is simpler: the newer version gives you the updated feature set without having to choose an older platform.
Who Should Buy Them?
The Bose QuietComfort Ultra Earbuds make the most sense for buyers who prioritize noise cancellation and a secure, customizable fit.
They are particularly well suited to:
- Frequent air travelers and commuters
- People working in noisy offices
- Listeners who enjoy energetic bass-forward sound
- Android users looking for premium wireless earbuds
- Anyone who wants wireless charging without buying a separate case
They are less appealing if your priorities are maximum battery life, an extremely compact case, or extensive sound customization. The $299 price also means shoppers should compare current alternatives and sales before buying. SoundGuys’ testing found excellent ANC performance, but also identified price and limited EQ control as notable drawbacks.
📌 Key Takeaway: The Bose QuietComfort Ultra Earbuds are strongest as premium noise-cancelling earbuds rather than all-purpose value earbuds. Their excellent ANC, flexible fit, immersive audio features, and wireless charging make them attractive, but the relatively high price and modest battery endurance deserve consideration.
Frequently Asked Questions
Are the Bose QuietComfort Ultra Earbuds worth buying?
They can be, especially if strong active noise cancellation is your top priority. The second-generation model adds wireless charging and improved voice pickup while retaining Bose’s CustomTune technology. At $299, they are best suited to buyers who will actually use those premium features rather than shoppers simply looking for reliable everyday earbuds.
How long does the battery last?
Bose rates the earbuds for up to six hours of listening per charge. Real-world results can be lower depending on volume and features. Independent testing measured roughly 5 hours and 34 minutes, so expecting the full advertised maximum in every situation would be unrealistic.
Are they waterproof?
They are rated IPX4, meaning they have protection against water splashes but are not designed to be submerged. They can therefore be suitable for ordinary workouts and light rain, but users should avoid treating them like fully waterproof earbuds.
Do the earbuds support wireless charging?
Yes. The second-generation charging case supports wireless charging, alongside USB-C charging. This is one of the clearest convenience upgrades over the original model and is particularly useful if you already use a wireless charging setup at your desk or bedside.
Are they good for phone calls?
The second-generation model improves voice pickup compared with its predecessor. Bose introduced enhanced voice-pickup processing, and independent testing found the microphone system capable of handling calls in different environments. Performance can still vary with wind, traffic, and surrounding noise.
Final Verdict
The Bose QuietComfort Ultra Earbuds remain a premium choice for listeners who put noise cancellation and fit ahead of everything else. The second-generation version does not reinvent Bose’s flagship earbuds, but its adaptive ANC improvements, better voice pickup, and built-in wireless charging address practical weaknesses in the earlier model.
For new buyers who frequently travel or work around background noise, the Bose QuietComfort Ultra Earbuds deserve serious consideration. Existing owners of the first generation, however, may want to wait for a substantial discount before upgrading.
