[This review was collected as part of a promotion.] Well they sound great once you get used to them but at first they almost feel like they will fall off because of where they go but they are pretty secure and will not fall off also remember that they are not as loud as the in ear ones which is something else I had to get used to but they still are loud for outer ear. Over all I like them once I got used to them.

Sound is amazing, and comfortable enough I forget they are are on my ears. Been using for sports, secure and sweat proof. Only complaint is microphones need work when in an echoing environment such as bathrooms and breezeways. The complaints come from the people I am speaking with. Overall probably a software issue.

[This review was collected as part of a promotion.] These are so good! Being open earbuds you would think that the sound would not be that good, but boy is it great! I have owned other types of open earbuds and these sound better by far! They are extremely comfortable and I wear these all day long. You can barely tell they are there. I would highly recommend these to anyone looking for a great pair of open earbuds.

[This review was collected as part of a promotion.] I bought my QuietComfort earbuds about two months ago, they are indeed very comfortable. The noise canceling is great. The fidelity of the sound is particularly good. I also have Bose headphones which I love. The headphones sound is a little fuller and richer sound than the earbuds, but the earbuds are still very good, and convenient for times when I don’t want a little less bulk than the earphones.

[This review was collected as part of a promotion.] I bought these and fell in love with these earbuds I wish bass was deeper. But the sound is outstanding. I have bought and tried many different brands and disliked all of them. I was even going to buy IEMS.

[This review was collected as part of a promotion.] I got these as a Christmas gift. Within two weeks they would not stay connected to my iPhone. The connection would randomly drop after just a few minutes. I ended up having to send them back for replacement. That meant I was without any earbuds for about two weeks. I was disappointed. The replacement pair seem to be functioning correctly so far. Although I’ve only had them approximately 2 to 3 weeks.

I bought my earbuds a few weeks ago and I’ve been so pleased with them. They fit beautifully and the audio features are wonderful. I can immerse myself in my music but still have access to the world around me. My husband loves that we can have conversations at the gym now that do not involve me pressing pause on my music or turning down the volume to be able to hear him. They are surprisingly comfortable and customized fit works great. I have an unusual ear piercing (anti-tragus) that I thought might be an issue but it’s not. Highly recommended!

Excellent sound and stay on well. I love the immersive option for music. I typically listen to audio books or podcasts in the regular stereo mode. Overall comfort is very good as it does not press too hard on the ears. I like to wear these around the house and when I walk outside so I can hear my surrounding some. I have not tried a phone call. I prefer my noise canceling ear buds for calls to block out any outside noise.

I bought this product about a month ago and overall it's been great. Being a lifelong Apple earbud user it took me a while to get used to the fit and feel of the Bose. Other than that I've been thrilled with the purchase; the sound is so much better than my previous earbuds!

With the Ultra-Open-Earbuds, I don’t have to worry about a perfect fit into my ear, which never occurs, and the sound is incredible. In my experience over the last several months, these buds remain stably attached to my ear even while I exercise. I avidly recommend the Ultra Open Earbuds to everyone.
