I bought these 3 weeks ago. At first, I thought they were great. They seemed to be clear sounding and the noise cancellation was great. However, I took them on a long flight and noticed that the noise cancelling did not filter out when airline workers were talking on the PA system. The talking was clear as day, which I was a little annoyed by. I don't know if that is a feature so users can hear airline workers but I could also hear conversations of those talking nearby clearly with the noise cancelling on, which I did not like. Later on in the flight, I also noticed that there was a weird grinding noise in my earbuds that was not present when I took the earbuds out. I intend to return these as the noise cancelling feature was not usable and had annoying side effects that I do not want to tolerate.

This is my 4th Bose headphone/earbud purchase, and the most disappointing. I'll start with the fact that these buds have their own separate app rather than being integrated into the "normal" app that I use for all the others. The earbud fit was less than comfortable and I found the sound quality average at best. I now own 14 pairs of headphones and earbuds and these will most likely end up being used sparsely at best.

Awesome sound I have owned many bose products and when I am looking for quality sound I have purchased bose.When I decide to look for quality sound earbuds I just purchased the Quiet comfort earbuds and again I am very pleased with the quality and awesome sound .

WOW! I'm impressed by the noise cancelation features of these earbuds. The best test was I used them while cutting grass. I COULD NOT HEAR THE LAWN MOWER! They are perfect for the gym. They tune out all outside noises. I lost my first pair of Bose earbuds... these are 10 times better. I can hear the faintest instruments in my music. Worth every penny!

These Quiet Comfort earbuds sound great. Especially with the sources they will actually connect to. But no matter what I've tried, they will not connect to my brand new Galaxy s25 ultra phone. So either help me connect, or help me return these things. Without a connection to my phone, they are less than half effective than I need them to be.

I have rarely been as disappointed in a purchase. I already have a pair of older Quiet Comfort that I am extremely pleased with: fit, performance, pairing, app, sound and noise cancelling These are the opposite in all those categories. The reviews said these were as good as the current Ultras. Not true for me. The price was right at the upper end of my price point. I should've passed. Also- why the hell are these made with the serial number in a position it's impossible for humans to read?

I’ve owned the earbuds for a little over a week and appreciate the terrific sound and noise cancellation. Bose is my go to for audio and has been for almost twenty years. Unfortunately I have to take one star off because the QCE app is a little buggy. I have to delete and reload the app every other day because it stops connecting to the buds for some reason.

Awesome sound. Amazing fit

Because of my positive experience I bought a pair for my daughter.

What a software disaster! Can’t turn off the voice prompt that talks EVERY time you put them in your ear - “Battery level 80%, Voice Commands On.” Seriously? Let me turn that junk off!!! Oh, and it autoplays every time you put them in your ear, and guess what? Yep, can’t turn that off either! The touch controls are too sensitive - don’t bother trying to adjust the fit. You’ll only Jack with every control there is. What a lousy design. Man BOSE is such a pale shadow of who they used to be!
