What Buyers Say
The biggest takeaway from user feedback is the exceptional noise cancellation, which many consider best-in-class, even surpassing competitors. However, a recurring complaint is the presence of a low white noise or hiss, particularly noticeable in quiet environments when no music is playing. While sound quality and comfort are generally praised, the battery life takes a hit with Immersive Audio, and the companion app is often criticized for being buggy and lacking customization. Call quality is improved but still not universally considered top-tier.
“Honestly, the ANC on these is insane, like, truly next level, but that constant hum when it's quiet? Drives me nuts. And the app is kinda garbage, Bose, seriously. Still, for blocking out my commute, they're kinda worth it.”
Common Praise
- The active noise cancellation is incredibly effective, making environments like planes silent.
- Audio quality is balanced, with clear highs, natural mids, and punchy bass.
- The earbuds are comfortable for long periods, with a secure fit due to the eartip and stability band options.
- Call quality is much better than previous Bose models, effectively reducing background noise.
- Immersive Audio creates a spatialized listening experience that's engaging for music and videos.
- Bluetooth multipoint connectivity works well for switching between devices.
Common Complaints
- A constant low white noise or hiss is audible when ANC is active and no music is playing.
- Battery life is only 4 hours when using the Immersive Audio feature.
- The Bose Music app is buggy and lacks essential customization for touch controls or notification volume.
- Connectivity issues like random disconnections and unbalanced sound are reported by some users.
- The earbuds and case are bulky, and the earbuds can be hard to remove from the case.
- Touch controls can be accidentally triggered by damp hair and lack audible feedback.
Ownership Tips
- The constant low hiss becomes more noticeable in very quiet environments, like at night in bed.
- Sweat can interfere with touch controls, leading to accidental pauses or skips during workouts.
- The USB-C charging port on the case can be finicky, requiring a specific angle for the cable to connect properly.
- Notifications, like low battery warnings, are very loud and cannot be customized or silenced through the app.
- Some users report the sound becoming unbalanced, with audio favoring one earbud, requiring a reset.
Frequently Asked Questions
Do these earbuds have wireless charging?
Yes, the charging case for the Bose QuietComfort Ultra Earbuds (2nd Gen) supports wireless charging, in addition to USB-C charging.
What is the battery life like?
You'll get up to 6 hours of battery life with Active Noise Cancellation on. However, if you use the Immersive Audio feature, the battery life drops to about 4 hours. The charging case provides an additional three charges.
Can I connect these to multiple devices at once?
Yes, these earbuds support Bluetooth multipoint, allowing you to connect to and switch between multiple devices like your phone and laptop simultaneously. They also support Google Fast Pair and Microsoft Swift Pair.
Is there a white noise or hiss when ANC is on?
Several users have reported a constant low white noise or hum, especially noticeable in quiet environments when no audio is playing.
How is the call quality?
The call quality is significantly improved over previous Bose generations, utilizing SpeechClarity technology and noise-rejecting mics to filter background noise. While it performs well, some reviews suggest it doesn't quite match the top-tier performance of AirPods Pro 2.
Buying Guide
When you're looking at wireless earbuds, especially ones with noise cancellation, you need to think about how you'll actually use them. Do you spend a lot of time on planes or in noisy offices? Then noise cancellation is key. Do you listen to music for hours on end? Battery life matters. And don't forget comfort – if they don't fit well, you won't wear them.
Active Noise Cancellation (ANC)
This isn't just about blocking sound; it actively cancels out low-frequency noise like engine hums or air conditioning. Think of it like a personal quiet bubble, making your music or podcasts clearer without needing to crank the volume.
Battery Life (6 Hours)
This tells you how long the earbuds will last on a single charge. Six hours is enough for most commutes or a long workout, but if you're on a transcontinental flight, you'll need to rely on the charging case or look for earbuds with longer single-charge times.
IPX4 Rating
This is a measure of water resistance. IPX4 means they can handle splashes of water and sweat, so they're fine for the gym or getting caught in light rain, but don't submerge them.
Immersive Audio
This feature creates a more spatial, 'out-of-your-head' listening experience, making it feel like the sound is coming from around you, not just directly into your ears. It's like having a mini surround sound system for your personal listening.
Alternatives
If the white noise is a deal-breaker or you need significantly longer battery life for immersive audio, look for earbuds with a reported 'silent' ANC floor or 8+ hours of playback with spatial audio features.
