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.

I wear them while I'm at work. The battery on the right side is done in 4hrs the left side makes just after 6hrs. That's inconsistent and way too short for a full charge. It's a shame because the sound is amazing. I bought the beats pro at the same time and they are still going the next day after 12hrs. The beats pro sounds terrible after listening to the boses

I have an issue with them staying connected even though I am sitting right next to my phone. They start to fade out then they snap crackle and pop then the lose connection. After a few seconds they pick back up and work properly for a hile then do the samething. Very Frustrating.

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.

I purchased these ear buds to use while walking my dog and for the gym. They have been incredibly easy to use and very comfortable. Even with my bigger hands and fingers getting these placed properly was a no brainer. Love the simplistic controls. I don't have to know Morse code in order to adjust volume, move between tracks or adjust spatial settings. Love the quality of the sound. While I haven't hit the limits on the battery life, but based on how much battery was left when I took them off (50%+) I expect they will be juiced for a full day.

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.

I had it originally purchased shockz open fit + 2 then ordered JBL 4 endurance earbuds returned both of them to go back to Bose earbuds by far the best quality best sounding best fitting earbuds on the market waste of time trying the other two products in my opinion Bose is the best sounding speakers/ earbuds thank you for making a great product.

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.

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.

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.
