[This review was collected as part of a promotion.] I have had my baby blue open ultra earbuds for 2 weeks. I have small ears and small ear canals, so I can’t wear regular earbuds. The open ultra earbuds fit great, but can somewhat easily be knocked off of the ear. I have thick curly hair, which helps to protect them from falling out. The only issues I have in terms of their operation is that 1. I have had trouble with the left earbud not working after I put them in and turn on the audio. I have had to take them both off and put them back in the charging case, then put them back in and that has worked so far. 2. I have had crackling connectivity issues even when I’m holding my phone or iPad. The immersive sound is amazing and the stereo sound is also very good. I’m not sure they are worth $300, but I do not have a lot of options with earbuds.

I bought these a week or so ago. The sound is awesome so are great for music, not so great on the phone calls, I've been told I sound like I'm talking from the bottom of a barrel, which is why I still use my shokz for that, but for music sounds and ease of use, Bose is still my number one!

[This review was collected as part of a promotion.] I LOVE my Ultra Open Earbuds! I love everything about it. They are comfortable and flexible and easily fits to my ear. Easy to put on and take off. I also like that they look like an ear accessory. I love the Carbon Blue color too. I’m really happy I got these.

[This review was collected as part of a promotion.] I’ve had them for 2 weeks. And I hate to love the fit they’re the most comfortable earbuds I’ve ever owned. However the technology just isn’t what I was hoping for. I can’t track them. I have lost them twice already. At $300 it’s not something I’m willing to overlook. I hope they add the ability to track in the future.

[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

I purchased these because I don’t like traditional ear buds that are lodged in the ear canal. Typical Bose sound with rich base and clarity of sound. Perfect for physical activity, the stay securely in place. I am able to interact with the world around me and hold conversations in the open air mode. Full immersion a simple touch of the ear bud transitions to full immersion for a complete Bose sound experience. Easy placement and removal. Very comfortable, when I am not playing music I have forgotten that I even had them on.

I bought these a few weeks ago. Very happy with the purchase so far. My first pair of open earbuds. Love the balance between listening to music and being able to hear what's around me at the same time. Comfortable to wear for extended periods. Simple to use.

Owning every earbud and headphones made I can honestly say these earbuds are the best ever. Bar none. They don’t enter the ear canal which iOS a huge deal since I wear aids. The fidelity is awesome and the comfort level is an eleven on a ten scale. I want to buy another pair I love them so much but the ones I have a so good. And the battery life is incredible.

[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.] After using these ultra ear buds for three days I’ve decided to return them for the following reasons. The volume doesn’t get loud enough. They hurt after wearing them for over an hour enough that I have to remove them for awhile. They look like ear rings so I would never wear them in public. I had problems getting them to work with my other Bose speakers. Incompatibility with other speakers. They sound good is the only reason they didn’t get a one star.
