Update: Bose replaced them with a pair of the QuietComfort Ultra earbuds. Those are also garbage.

Real comments from Reddit, linked to the original thread. Nothing paraphrased.
I've had such a myriad of issues with them, I've had to have them replaced 3 times due to seal and charging issues. And even when they function as intended, the slight buzzing interference in the left earbud is extremely noticable and obnoxious, especially in quiet environments (And this is apparently intended behaviour), not to mention connection issues (Randomly turning off, dodgy in-ear detection) ... Your money is better spent on literally any other product on planet earth, please do not buy this terrible, terrible product.
Complaint
Here’s my update: they sound really good immersive mode is good for some songs but really good for movies, music videos and YouTube content. ... Noise cancellation is G tier awareness mode is good too but needs a little work. ... I was gonna get the WF1000XM6 but these bad boys have grown on me a solid 9.5/10 overall.
Praise
I have the bose quiet comfort ultra earbuds and I'm having the static in the left earpiece right now as I type this
Complaint
I cannot stress this enough, do not get the Bose QC earbuds. They are notorious for not connecting, not syncing, and stopping working altogether.
Complaint
Those earbuds look tight. ... Sounds great.
Praise
I've been hearing this damn mosquito noise in the left bud for months and finally bothered to look it up tonight.
Complaint
The ANC is...unbelievable. It is miracle-level good. If ANC is your priority, get a Bose.
Praise
I've gone through 8 different pairs, every single pair had some issue and had to be sent back. STOP BUYING THESE EARPHONES, they have noise-cancelling functionality that is superior but don't last.
Complaint
Made two flights - absolutely amazing ANC, use for running and outdoors- never felt that they would slip out! ... Ticks most boxes!
Praise
Conclusion: Sensational. ... The ANC is incredibly good. ... Clear purchase recommendation!
Praise
The promised aptx adaptive and aptx lossless for the QC earbuds ii just became a whole new product instead. Well done Bose
Complaint
Maaaaaybe you have a defective pair?? lol imagine thinking your experience is universal
Comparison
The endless complaints about Bose continues. ... I wonder what quality control issues cost them
Complaint
everything else feels about the same , No static on left yet but that was also the case with the original ultra before the static noises started later down the line. ... Ill test some more but I highly doubt i'm keeping these ... pretty poor from Bose really.
Complaint
1) They fix the mosquito buzzing in the left ear. 2) They fix the connectivity issues so there aren’t any. 3) They increase microphone quality. 4) They make the earbuds all around less buggy. Qi charging is not enough of an upgrade to warrant buying these, they’re essentially a firmware update in a “new” hardware package with a new charging case that should have been with the QC earbuds II.
Complaint
I returned my WH1000XM6 and brought the Bose. And they are awesome; I wore them to the cinema for my first test, and the noise cancellation was awesome for the ads and crowd noise (obviously, I took them out when the movie started). Today I wore them to the gym, and I could only hear my music. The aware mode is good enough, and the best part for me is immersive audio is great too.
Praise
I really regret buying mine also. Replacement issues connecting issues now charging issues. I’m on my third pair there won’t be a fourth.
Complaint
Just purchased the Ultra Earbuds for $269, shipping in early October. Hope they stay on better than my Apple products.

✅ What Works
- Strong ANC praised repeatedly, especially on flights and in gyms
- Immersive audio mode and aware mode get solid marks from multiple owners
- Qi wireless charging is a welcome upgrade over the previous generation
⚠️ Worth Knowing
- Persistent "mosquito buzzing" static in the left earbud reported across multiple separate owner threads
- Recurring connectivity dropouts and pairing issues
- Multiple owners went through 3 to 8 replacement pairs with the same recurring defects
- Seen by some as a minor firmware-level update over the original QC Ultra, not worth upgrading for
ClearPick Verdict
Reports on the Bose QuietComfort Ultra Earbuds (2nd Gen) split sharply, with negative mentions nearly outnumbering positive 2-to-1 (11 of 19). The most common issue is a persistent "mosquito buzzing" static in the left earbud that several owners say Bose support calls "intended behaviour," plus recurring connectivity dropouts — one owner went through 8 replacement pairs, another through 3, all with the same defects, across separate reports. Positive reports praise strong ANC on flights and in gyms and a solid aware mode, and Qi charging is a welcome but minor hardware update. Given how consistently the static and connectivity issues appear across multiple separate owner threads, buyers should go in aware this is a known, recurring pattern rather than an isolated defect. Good if ANC quality matters most and you're prepared to exchange a defective unit; skip it if reliability is your top priority.
