I bought it about 3 weeks ago, and I love the pure sound and the noise canceling, however the ergonomic shape i found a bit bigger for my ear, doesn't fit perfect and I'm scare to lose at some point.

These Bose Ultra's are the ones! I have tried them all. Absolutely fantastic! Purchased for my Spouse for Christmas. I wore them for almost 8hrs. I'm sold. That day I ordered another pair for myself. Excellent innovations Bose! Thank you... don🇺🇲

I bought these a couple of weeks ago and so will be returning them. Sound quality is terrible also the volume is basura. No thanks. They’re super cute but not of quality sound wise which was extremely shocking.

Finally. Earbuds that sound great, and with the retention rings, stay in my ears as well. I had to give up on the Apple earbuds because they kept falling out of my ears. I finally gave up on them because one got lost during one of my daily walks.

I bought these because I have tinnitus and felt that my earbuds were making it worse. I wear them about 8 hours a day because I drive for a living. I like the convenience of these but I am still getting used to them.

They are comfortable. Sound quality is good. Battery life is horrible. I can't make it through an eight hour shift even if I'm not actually using them, there just in my ear.

I bought them hoping they would block the noise of my very loud lawn mower. They did an excellent job. I can now listen to podcasts whilst mowing my lawn.

This is another great Bose product. I was initially concerned that the design would not hold the buds in place while I run but that’s not the case. They are very secure once they are on and again, the sound quality is excellent.

These are SO cool. They don’t fall out of my tiny ears, the sound is awesome, and they look good. Favorite going out lil blk dress trimmed with gold jewelry….it all matches

This model is a definite upgrade from my earlier QuietComfort buds, although I haven’t found the sweet spot on programming so I can change modes without the app, increase volume and go forward and back in small increments.
