The sound is great and they are comfortable. I haven't had them long enough yet, but the mic isn't that great for the person at the other end to hear clearly (this is my only concern so far). They definatly cancel most all of the outside noise, so far I have no problems with the battery life. I not abusive with stuff like this so I don't know about the durability yet.

I’ve now had 3 pairs and all have had issue, first pair would not charge equally, they both started at 100% then the right side would drop to 10% less than the left yet both would shut off at when the right side discharged they were replaced with a pair the microphone didn’t work very good and couldn’t be heard on phone calls now the third pair has both issues. Right side discharges faster than the left and microphone is terrible plus the speakers are terrible, top volume is barely audible with any sort of background noise. Now they’re unable to replace the latest pair due to insufficient stock on the colour.

Replacement set as originals developed a mic issue. Absolutely love the open ear buds - super comfy and sound quality is brilliant. Only downside is original colour out of stock and I wasn't willing to wait any longer so opted for another colour which I'm not so enamoured with.

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.

Not so happy with this purchase. When I first opened it up, my first thought was, I love this color!. Then when I grabbed it out, it was light and flimsy, cheaply made. I have 5 different Bose earphone products. This by far is the worst. The noise cancelling isn’t as good as my Apple earbuds. The quality of the buds are crap, you would think because it’s light, that it’d be comfortable, but it isn't. I wore them for two hours and my ears hurt. The color is pretty. But the product wasn’t what I expected out of Bose. Don’t buy these if you have other noise cancelling earbuds.

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.

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 fit comfortably in one's ear. The sound is sharp and noise cancellation is awesome. They are very sensitive to light touch so you have to make sure you don't try to adjust them or light ly touch them while you are on a call. All in all they are wonderful and worth the investment.

Wore these brand new earbuds for a run. I made it 3miles before the left earbud stopped working and now either squeals a loud tone or just a thump but no sound before turning all the way off. I’ve now had these not work during runs, the QC version 2 stop working, and the ultra free open ear earbuds stop working from fitness. Bose is not durable enough to last their year warranty and they only replace items once with à refurbished pair that last typically about 100days. Very very disappointed Bose has turned to crap.

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.
