Bose QuietComfort Ultra Earbuds vs Sennheiser Momentum True Wireless 4

“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.”

“I’ve had these for about a week, mean I find they sound way better than my sennheiser momentum buds & Sony, I went back & tried my sennheisers & didn’t realised how bloated they were”
