Bose QuietComfort Earbuds II Review: ANC Leader with Flaws
Few earbuds inspire such polarized feedback as the Bose QuietComfort Earbuds II — hailed by many as “the strongest ANC on the market” yet dogged by persistent connectivity and comfort complaints. Aggregating thousands of reviews, they land at a solid 8.3/10, particularly for noise cancellation and sound, but with caveats that certain users should note before buying.
Quick Verdict: Conditional buy — best-in-class ANC and very good sound, but intermittent connection issues and missing premium features may be dealbreakers for some.
| Pros | Cons |
|---|---|
| Industry-leading active noise cancellation | Connectivity issues, especially with iOS and Bose app |
| Rich, well-balanced audio with adjustable EQ | No wireless charging |
| Smaller, more compact design than first-gen | Mediocre battery life (6 hours max) |
| Secure fit with customizable tips and stability bands | Microphone quality underwhelms in wind/noisy environments |
| Highly effective “Aware” transparency mode with Activesense | Limited codec support (SBC and AAC only) |
| Great call clarity in quiet environments | Hissing reported in aware mode in silent spaces |
Claims vs Reality
Bose pushes the “world’s best noise cancellation” message hard, and for the most part, users back that up. A Reddit user described commuting with them as “like being in a room behind heavy steel doors, locking out all external sound sources.” On Reddit, even long-time AirPods Pro users admit Bose “beat out most over-ear headphones” for ANC strength.
Marketing also promises “custom tune technology” that personalizes sound to the wearer’s ear. Many Best Buy purchasers note this yields a rich, “immersive” stage without harsh highs — “balanced, enjoyable audio” as one verified buyer reported. However, audiophiles in T3 and TechGearLab testing point out that without aptX or LDAC, Android users can’t unlock hi-res playback, and subtle compression is audible on complex tracks.
Bose claims “reliable Bluetooth 5.3 connectivity,” but community feedback paints a split picture. Some Redditors “never had issues” across many devices, while others report a 4-to-1 ratio of problem cases: app not seeing the earbuds, random dropouts, and one bud failing to connect. As one frustrated Reddit user put it, “about ¼ of my time… has been spent fighting with them to work.”
Cross-Platform Consensus
Universally Praised
No matter the source, ANC is the standout star. TechGearLab measured up to 42 decibels of reduction across mid and high-frequency noise — “low-pitched hums vanish, high-pitched whirs disappear.” Gym-goers love it for silencing “HIIT class music and instructors shouting through mic,” keeping playlists clear at modest volume. Home workers cite it as a “life saver” against loud HVAC units and noisy family environments.
Sound quality earns consistent praise. Bass lovers celebrate how genres like EDM and hip-hop pop with “fully fleshed, warm lows that never overwhelm,” while vocal-focused listeners enjoy “impressive levels of detail” in midrange that make singers sound present and emotional. Even casual users remark that they “absolutely love the crisp quality of sound and thumping bass” without ear canal pressure.
Fit and stability, aided by Bose’s “fit kit” with three ear tip and stability band sizes, is another win. Users with small or asymmetric ear canals find these “the most comfortable” buds they’ve worn, staying in place through head movement and workouts, unlike the first-gen.
Common Complaints
Connectivity troubles dominate the downside narrative. The Bose Music app is frequently labeled “useless” or “buggy,” failing to recognize paired buds or freezing during updates. iPhone owners seem disproportionately affected, with Reddit user a-red-guitar-pick calling them “the most unstable connection experience” seen across any brand.
Battery life is a clear weak point for power users. With ANC always on, six hours is the ceiling — below rivals like Sony’s WF-1000XM4. T3 notes there’s “no way to disable ANC to extend runtime,” forcing mid-day recharges for heavy listeners.
Feature omissions frustrate brand loyalists: no multipoint connectivity, no wireless charging, and codec support limited to SBC/AAC. Android audiophiles feel especially shortchanged compared to competitors at the same $299 MSRP.
Microphone performance is inconsistent. Indoors, call quality rates highly, but in wind or car A/C airflow, callers report muffled or “tiny, tunnel-like” voices. For field workers or outdoor runners, this could be a dealbreaker.
Divisive Features
Aware mode, Bose’s transparency implementation, sparks debate. In noisy environments, Activesense smoothly tames loud spikes without killing ambient awareness, which commuters praise. Yet office users complain of an intrusive hiss — a Redditor measured “about 32db” noise floor in aware mode and returned them solely for that reason.
Touch controls feel polished to some, finicky to others. Swipe volume is lauded for fluidity, but tap gestures can miss inputs, particularly when buds are wet or rainy exercises are involved.
Trust & Reliability
On Reddit, multi-month owners show mixed durability. Several switched to Bose’s newer QC Ultra after warranty replacements, citing hardware faults that “came out of nowhere.” Others kept their QC II for years without any degradation in sound or ANC. Trustpilot and forum users commend Bose’s “best customer support by a mile,” with some scoring free Ultra upgrades.
No scam behavior was noted, but long-term reliability concerns are rooted in electronics that seem sensitive to firmware updates. The community workaround: some users “deleted the app” to end pairing headaches — sacrificing in-app EQ and firmware updates.
Alternatives
Comparisons surface repeatedly with Apple AirPods Pro 2, Sony WF-1000XM4, and Bose’s own QC Ultra. AirPods offer better iOS integration, multipoint-like handoff, and spatial audio, but ANC falls just short. Sony’s XM4s bring richer codec support and longer battery life, but fit and comfort divides opinion.
One ex-QC II owner who returned them wrote: “AirPods Pro call quality is superior… music playback not as nice as Bose.” Meanwhile, QC Ultra owners confirm the ANC edge remains but note added features.
Price & Value
Current eBay prices show wide variance: sealed new units from $159 to $320 USD, refurbished dipping near $135 USD. Long-term value depends heavily on whether Bose addresses firmware/app woes. Community buying tips include purchasing direct from Bose for their 90-day money-back guarantee and coupon stacking, or grabbing Amazon sale pricing at ~$199.
FAQ
Q: Do the Bose QuietComfort Earbuds II have multipoint connectivity?
A: No. They can remember up to seven devices but connect to only one at a time. Switching requires manual selection in Bluetooth settings.
Q: Can I turn ANC completely off to save battery?
A: No. ANC is always active, though you can lower it via custom modes. Many users note battery life does not improve significantly at lower ANC levels.
Q: Do they support aptX or LDAC for high-resolution playback?
A: No. Codec support is limited to SBC and AAC, which is fine for iOS but may limit Android audio quality.
Q: How do they perform for phone calls outdoors?
A: In quiet settings, call clarity is excellent. Wind or direct airflow can severely reduce microphone quality, causing muffled voices.
Q: Is Bose’s “Aware” mode as good as Apple’s transparency mode?
A: It’s effective for balancing ambient sound with music, but some users dislike the audible hiss it introduces in silent spaces.
Final Verdict: Buy if ANC dominance is your priority and you can tolerate average battery life plus occasional connection quirks. Avoid if seamless multi-device use, wireless charging, or wind-resistant call mics are critical. Pro tip from the community: if connectivity falters, try removing the Bose app — it may eliminate headaches without sacrificing core listening performance.
