Bought these for my partner to replace an older version of a similar model as we couldn't get proper silicone replacements for them. He feels the case feels cheaper, I think it just feels lighter and a nicer texture. He liked the button to open the old case, this one doesn't lock and just opens. Sound quality is as expected with any Bose product - very good! And he finds them very comfortable. Still wish we could have gotten replacement covers as there was nothing wrong with the old pair and they still worked fantastic (about 5 years old)

These contain all the quality and depth of sound I:be come to expect from Bose. I've tried multiple earbuds (wired and wireless and I continually had problems with keeping them in place if I as much as took a deep breath. These ultra earbuds stay in place with any activity I have taken on in the 2 months I've had them. I have had a couple of occasions where I had turned off the my music on my phone and didn't realize the earbuds were still on until someone asked me what I was listening to. They're so light and intrusive that I still had them on. As always, great job Bose!!

My comment pertains the second pair I own: I lost one of my previous pair (see CONS). PROS: 1- The Bose sound is great; 2- They very comfortable to wear, actually more comfortable than the in-ear models of Bose; 3- They last for hours of continuous use and charge reasonably fast; 4- Even though they are open-ear models, they are very quiet so I can use them even when my wife sleeps next to me; 5- The attachment system is very stable under most (but not all - see CONS) conditions of use. 6- Being open-ear, the earbuds allow the ear canals to stay dry and fresh, which is fantastic during the hotter months or when using them for long periods of time. CONS: 1- As compared to the in-ear Bose earbud models that I have owned previously, the microphone of these earbuds is not sensitive enough to catch my voice during phone calls. I have to commute to the phone mic to answer a call, which I can do while wearing the earbuds; 2- Beware when wearing a hoodie while using the earphones: when covering your head, the hoodie can swing an earbud out of the ear. It would be great if the earphones had something (e.g. a hole in the silicone piece that links the speaker to the base) to fasten a lanyard for preventing their accidental loss; 3- Sometimes the sound of the earbuds desynchronizes for a few seconds.

Love these!!! I am a runner and have been using another style/brand for a few years and they are fine in the warm months, but I was so frustrated when I needed to pull a warm hat over them. The hat could never fully cover my ears. These are like wearing nothing and now my ears stay covered and warm. Game changer!! And the sound is amazing!!!!

I bought them for myself, I always have headphones with one ear open so I thought they would be great. BUT they didn't fit my big ears, they are super comfortable but they way the perched they didn't hit my ear canal well ... note I get the biggest hat from the big hat store, so naturally I have odd shaped ears I guess. But I sold them to my son and they fit perfectly and he loves them. So big win there! I went with a traditional overear headphone and resolved that earbuds and open air ear cuff types just don't work for me. /shrug. it is what it is. big head, big feet, big ears, what's a guy gonna do.

I am still on a learning curve in terms of the features of the Ultra Open Earbuds, but so far it has me in awe of the capabilities and features.

Purchased for my son who lives and works in NYC. The only complaint he has is the connectivity while traveling in the city.

Purchased these for my daughter since the in ear version hurts her ears. She loves them! Bose for the win!

These earbuds work well, but they are not easy to pair. I had great difficulty pairing them with my iPhone.

I bought it a couple of weeks ago and love them. They are easy to setup, sound quality is great, and the fit is perfect for me.
