They sound good. The issue is either they don't fit my ears properly or they need to be louder. The units might need to be a few millimeters deeper in my ear to be louder. When I press them down a bit they are a better volume. It's possibly an issue with my ears not the units.

Bose never disappoints and sure didn’t with these. The sound quality, app features, and comfort make these well worth the price. I’m new to the open ear concept and took some getting used to, but the immersive feature is incredible. You won’t be sorry I promise.

[This review was collected as part of a promotion.] I bought my Earbuds about a month ago and I have no regrets. The buds actually exceeded my expectations for the open ear design. I really appreciate the ability to enjoy my music while having the ability to engage in conversation.

I have been using the ultra open for a little bit. For comfort and ease of use at work on constrution sites i would give these a 10 out of 10. I have had a few times where they have waivered with signal with the phone in my pocket. The sound is great when positioned properly. Talking on them sucks. Everyone keeps saying "can you repeat that". Hence the reason I couldn't give it 5 out of 5.

It is good for playing sports but there is a difference with the Bose QuietComfort Ultra Earbuds and this one The intensity of the sound is less than Bose QuietComfort Ultra Earbuds because this one are open If I have known this I would have not bought this one but theBose QuietComfort Ultra Earbuds The speaker (Bose Ultra Open Earbuds )may not lie close enough to the ear canal ( this depends if you have big ears or not) so the intensity of the sound is not good

Really interesting product that has niche application making it difficult to justify spending 300$. I wear earbuds most at night and within my home, which they are perfect for. If I were still in school studying and wanted noise cancellation this would not be the best product. Also functional, but not as compatible with apple products as AirPods (obviously). For example, music doesn’t stop, sometimes doesn’t auto connect, etc.

[This review was collected as part of a promotion.] I am a runner and the Bose Ultra Open earbuds are a perfect choice for me because they are comfortable, stay in place, and I can hear the traffic around me. My use of them have evolved into taking them to the office with me also. I would definitely purchase them again.

[This review was collected as part of a promotion.] Bought a month ago because my apple airpods kept falling out while I was working out. These never fall out, whether i'm running, doing situps or planks. they are also comfortable. i've tried clip on headphones in the past and had a pinching sensation. high quality audio.

[This review was collected as part of a promotion.] Bought 2 wks ago but had to return concept was good. But sound was not enough for me to appreciate. It holds perfect on my ears all others innovation was great. Just the sound not loud enough for me. Bose fan forever.

[This review was collected as part of a promotion.] I have tried several earbuds that didn’t fit or fell out. Also had some with very mediocre sound These have an excellent sound and stay on my ears easily. They do take a little getting used to because of the position on ear but I really like them
