Best praise vs top criticism for Bose QuietComfort Ultra Earbuds
Best Praise
+3 pts“Just bought the QC Ultra. I also found them uncomfortable until I read the fit guide. I forget they're in my ear after some adjustments. If you still own them, give it a shot.”

+2 pts“Ultra struggles with multiple connections and hissing sound. Ultra earbuds, identical multiconnections, occasionally when I walk, the sound cuts out as if I've turned them off, yet they remain connected, quite strange. There’s a hissing sound when I use ANC, and at times, I notice an odd noise after watching videos on YouTube, TikTok, etc. QC makes a buzzing sound when I transition between YouTube videos, and 2 times I had disconnects. QC earbuds occasionally stop working unexpectedly, I never configured them to turn off. The left earbud doesn't function when I take it out of the case, only when it feels like it. The multi-connection feature is also poor; they lose connection randomly and then reconnect. Wtf is this, right? I do possess more earbuds and headphones, and in 27 years, I have never encountered these problems with a new product priced at half of Bose items, like Melomania M100, Sony LinkBuds S, Technics AZ80, Anker Q35, etc. I can't express how terrible the customer service is, absolutely awful. The comfort and ANC are excellent with Bose; I definitely prefer the sound over Sony's, no contest! I share this so you know what are the true experiences with this product, you can ignore me and buy all of them, but please to not hate people that tell the true, I hope I didn't waste my time typing this much.”

Best praise vs top criticism for Denon PerL Pro

+31 pts“I too used to think that BT is barely passable at least in SQ so I stopped spending money on it & just lived with a Jabra H85 fullsize can. And I had some cheap $15 BT neckband earbuds I used for riding EUCs. Did the job but never expected much. That was then & this is now. I saw a Denon PerL Pro on a Prime Day deal & figured why not easy return if it sucked. Well… it blew me away. Soundstage, imaging, clarity, sweet vocals, bass that doesn’t just boom but actually talks. I know you’re not trying to drop $$$ or chase audiophile gear. So for that I'd honestly look at the \[Tagry bluetooth earbuds\](https://LaunchDeals.github.io/Value/?to=what\_are\_the\_best\_cheap). They are on Amazon rn for like \~$25 (they’re listed at $49 but often on sale). For the price they’re shockingly solid. Battery life is a beast, 60 hours total, and the case doesn’t flake out like Skullcandy’s tends to. LED battery display, wireless charging, decent mic and a comfy in ear fit right out of the box. Sound wise: No ANC but the passive isolation is enough for everyday stuff. Nothing overly boosted.. just clean, balanced playback”

+5 pts“Denon Perl Pro. They sound bad and the sound customization made them worse. Also incredibly awkward to wear and take out and put in the ear and case.”
