Had it for several months. Good sound, not much bass. I got open style so I wouldn't have hearing loss in my old age. They are comfortable and do not fall off when I'm working out or running. I'm able to ride a bike or run and still be able to hear outside noise. You will not be able to listen to music if there is a lot of ambient noise such as an airplane or at the gym if there's very loud music already playing overhead. I am not sure if mine is a dud but I have not been able to do any phone calls with the device. I can hear them but People on the other line cannot hear me when I'm on a zoom call or phone call. Hopefully version 2 is better

[This review was collected as part of a promotion.] I bought these to try out the open earbud concept, and purchased refurbished to save some money since I heard good things about Bose's refurbished program. My other earbuds tend to fall out of my ears when I'm moving around or active, and these stay in place really well. I also really prefer to use the Bose Ultra Open Earbuds for meetings, so I can hear myself in the conversation in a more natural way, instead of only being able to use one earbud or hearing my own voice muffled in meetings previously. These are the most expensive earbuds I've ever purchased by far, but for around $200 refurbished I am very happy with them so far. I'm not sure I would pay the full new price, but I appreciate that refurbished is offered for that reason.

[This review was collected as part of a promotion.] I bought these because I do not like things in my ears. No matter what size rubber piece I put on the earbuds they never fit properly or they always came off in my ear. I was skeptical of these type of earbuds. There was no way I was going to be able to hear anything or everyone will be able to hear my conversation and what not. Let me say this. These are money worth spent. I will never go back. I can hear everything and noone can hear what is going on, unless we are ear to ear. Lol. They are comfortable and don't slide or fall off.

[This review was collected as part of a promotion.] I mostly use these as sleep buds. I have pretty extreme tinnitus, use a CPAP, and can have other problems with sleep at times. I find using these with soothing music and sounds, helps me enormously. They are way more comfortable than in ear buds, and headphones. Being that they are more at risk of being knocked off of my ears, I only use them where I can find them if that happened. But that's OK, as they are so great for what I use them for. I have not one but two pair to be sure I have at least one set charged at all times.

My wife has a pair of bose earbuds and works from home. I bought the ultra open earbuds to help her hear the open meetings that she usually attends through conference calls. I asked her to try them out and she was excited about the new design. She gave me the quiet comfort earbuds and now she can enjoy her music and meetings at the same time. Thank you for the new product.

[This review was collected as part of a promotion.] These are easy to put on and take off. They sit lightly enough on my ears where I don't feel them. I have been able to easily bluetooth connect them to my smartphone, tv, desktop computer, and laptop. The sound quality is amazing and what I've come to expect from Bose. I have driven with them in and feel like I can still hear all the things around me and am not being a danger to myself or others. I wear earrings and sunglasses almost everyday and am able to wear these earbuds without them interfering with those items. There are just a lot of click the earbuds button shortcuts that I had to get used to.

I absolutely love my Bose Ultra Open Earbuds, they're pretty much the only thing that could've made me upgrade from my Bose QuietComfort Earbuds. They stay in/on my ears, and they're so comfortable that I honestly forget I'm wearing them, which is just this side of miraculous because I have really tiny ears and even the smallest size earbuds end up being painful and/or annoying after just a few minutes. And the sound is, of course, amazing. I already own three pairs to ensure that I always have a pair at hand. That's how much I love them!

[This review was collected as part of a promotion.] These headphones are the most comfortable open earbuds I've ever used.I've used Shokz's Open fit and Huawei's open earbuds.The Bose gave me the best wearing comfort of the three.The music experience is also perfect.While it has to go without saying that in some ways, this should be a problem at the firmware level, Bose will fall short, and I have summarized the problems that have arisen in a month of use.Hopefully this can be improved in subsequent version upgrades. 1 During normal press time, there is a short disconnection problem. 2 The microphone sound is too low when talking outdoors. 3 I don't have a way to check the charge level of the charging compartment through the app. The advantages 1 Very comfortable to wear 2 Sound quality is excellent 3 Responsive, very low latency Bluetooth connection. 4 Indoor and outdoor automatic volume adjustment.This is very practical.

Super easy review because these are probably the best earbuds that I've ever used. They feel super light and I an wear them all day at work around the office and my ears don't get tired. They also have an aware feature that actually allows me to hear everything going on around me too. The sound quality is as amazing as you'd expect from Bose, and these are cool because you can customize the sound settings a lot through the app. Finally, they look amazing and have a nice finish, and the battery life is great. I've gone a few days on a single charge. One thing is the case doesn't easily fit in my pockets, so I have to put them in my bookbag or gym bag, but I'm hoping to get a case soon with a hook or carabiner.

Bose Ultra Open Earbuds are amazing for music lovers like me who want to enjoy rich, immersive sound without blocking out the world (or blocking out their loved ones!). They fit comfortably and securely around your ears (way more comfortable compared to other premium headphones), and have long battery life. These open earbuds are perfect for running, working, or relaxing with your favorite tunes.
