[This review was collected as part of a promotion.] I love these earbuds! I have smaller ears, so in-ear buds usually hurt after a while, but these feel great even after hours of wear. The sound quality is really top notch as well. I like that you can change the mode from immersive to stereo, which really makes a difference if you are moving or not.

I purchased these a couple months ago as I am training for my second marathon. They are light and give off great sound while being able to hear around me. We all know there are some creepers on the trails so it's important to not have complete noise cancelling while running those trails.

I have had these for about 10 months. They have incredible battery life, good sound, can hear surrounding sound if you need to. The cons are the quality of sound is not what you get from other Bose earbuds. They are as comfortable as I wanted either.

Awesome sound, but wish it was a bit brighter and stronger at higher volumes, which is needed for running. If I sit still in a quiet room it is quite nice. When I need at higher volumes, the EQ seems to change to a lesser brilliance & power. I'm still not sure. The thing I like best as a runner is no stomping sounds in the ear buds! So annoying! So, this aspect is great. But! I live great audio too. One running review said the Comfort version provides both stellar audio & no stomping feedback.

I've had these since they came out and I don't regret the purchase at all. Sound quality is great, although they lack a little bit on the base end of things. However I don't typically listen to music for the bass so it's not something I miss. Take these running with me and it makes it easier to talk to and listen to my daughter, who goes with me, and I don't constantly have to adjust the volume or press anything to stop the music. They stay in place, don't slip or move. Recommend for anyone with an active lifestyle.

[This review was collected as part of a promotion.] Had these for about a month and they make my travel on public transportation easy. I am able to still hear what's going on around me while all listening to my music or having a phone conversation. Also with my ear piercings, these headphones do not irritate my ear which is an extra win for me!

I got the earbuds close to a month ago and I am so disappointed. The first earbuds to have the noise control feature for 8 hours! That means that they can be used to sleep. And yet, they have the initial voice prompt that can't be turn off. If they move a little there is that prompt again that wakes me up time after time. What a shame. So awesome but I have to return them.

[This review was collected as part of a promotion.] Best earbuds I have ever owned. Easy to use and never fall off. I always have issues with in ear earbuds. These allow me to do anything I want and also hear anything important outside whatever is playing on my Ultra Earbuds. The sound is spectacular.

After personally having used the earbuds for a few weeks I thoroughly enjoy them. They have quality sound and bass as does all Bose products. Pros: easily put them on your ear, cause no discomfort to my ears after wearing all day, the Spatial Audio feature allows for a more rich sound when listening to music or watching something, the battery level lasts a very long time I was consistently using them throughout each day and didn't have to charge them until about a week later, having the button instead of swiping motion allows you to have a “shortcut” set up but also control the volume instead of having to put the volume control as your shortcut like previous earbuds. Cons: there is no active noise cancelling and depending on what you are doing this can be annoying or could be a benefit, because of the style they don't sit directly in your ear therefor someone next to you can still hear what you are listening to if they are loud enough, the button to control sits behind the ear and does make it a little trickier I feel to get to compared to the swiping and taping motion previous earbuds had. Overall I enjoy these headphones and will continue to use them.

[This review was collected as part of a promotion.] I brought these a month ago, and I love them. They sync well to both my phone and my galaxy watch. I get plenty of hours listening time. The best part is when I run early morning, I can play my music and still hear the sounds on the running trail. Same thing when I bike ride, I can hear around me and still listen to music with quality sound.
