The sound of these is phenomenal. The battery life is great. I haven't quite gotten the fit right and am still experimenting to see which tip and which wing works best in which ear. The only 2 things I have issues with are the touch sensitivity, I appreciate all of the functions available but anything that even grazes one of the buds stops the playback, and the voice control. When it works it is fabulous but unfortunately unless you are in very quiet surroundings, the microphone is overwhelmed and simply doesn't work. I would highly recommend these, they just need some getting used to,

Another pair of ultra open and this is better than the original, still stays on my ears but with more clarity and battery last longer with better sound. Feel least isolated with these and more in tune with what is playing in my ear; coming right at you.

This ultra open ear buds just fit my lifestyle and not only it looks nice, it fits my ears well. The sound is great as well as the features. Battery holds up well and music is clear. I do not have any regrets with this purchase. Bose always never disappoints.

They work ok. Sound is not full and my ears are normal size. If i really press and direct the sound its great but just cuffed on the ear it is not so robust. Cuff feels great but the sound just doesn't get to the ear they way i thought it would. It does what they say and you can hear stuff around you while listening to music when you are walking or doing light stuff but i went biking and did a faster pace for 20 miles and had to have the volume all the way up and it was pretty quiet actually. I am probably going to return because it just doesn't seem to be worth the hype. I bought the 3 year warranty too so Not cheap. Not my favorite BOSE product and I have many.

These earbuds are high quality with great sound. I received them within a few days! I've had them a week now. My concern is the fit of the ear piece. Also of concern is the lack of sound isolation; maybe I'm just use to the sport buds or over ear head phones. They worked best when I placed a headband over my ears. I shouldn't have to be that way with a product from Bose.

Never thought I would like or even have an interest in open ear earbuds, I was all about noise, cancellation. However, I am so incredibly pleased with my open ultra earbuds that I'm sorry I did not get some sooner. Comfort, clarity, and versatility. And of course, Bose quality that is unmatched.

The sound is good. However, they do go out periodically even when my phone is right there; sometimes both, other times only one side. Also when you tap to pause, it pauses, but then moments later starts without me touching it. These are both inconsistent.

The Bose Ultra Open Earbuds deliver exactly the sound quality you would expect from Bose, with deep lows and crisp, clear upper notes. They are also surprisingly comfortable, offering excellent weight distribution and just the right amount of pressure to remain secure without feeling restrictive. Unfortunately, while many customers may find them comfortable enough for all-day use, they may not be a good fit for people with larger ears. There simply is not enough material between the speaker and the portion that wraps around the back of the ear. As a result, the speaker may not sit deeply enough in the ear to produce the best possible sound, which noticeably affects volume and overall audio quality. The wireless charging case works great, but I wish wireless charging were included with the standard case rather than requiring a separate purchase. Overall, these are thoughtfully designed earbuds with impressive sound and comfort, but the fit did not work well for my ears. I will be sticking with the Bose QuietComfort Earbuds, which provide a much richer sound and a better overall fit for me.

I was so excited to get these ear buds. But I have to say, I'm super disappointed in the battery life. After a full charge, (I timed it this morning) at 100%, I started my audio book at 8:58 am and at 3:33 pm, my right earbud died. The right always gives out first. Super disappointing. The left will get about another 20 minutes, then it will die. I had Tozo earbuds for a couple years and admittedly the sound quality and clarity wasn't as nice and clear as Bose. When I first got them however, I could go 2 full 8-hour workdays (I actually think 3 days) before I needed a charge. The Bose fit well and are comfortable, but not more comfortable than what I had previously. All in all - they're fine...but not for the money.

I bought these a month ago. The fit is very good. Clarity is not very good. Sometimes I gave to rewind to hear a word or a sentence. Noise cancelation is not as good as ultra. Also it crackles and I am wandering if they have a technical issue. The range from the source is decent.
