I’ll be honest. When I first saw someone wearing the Bose Ultra Open Earbuds, I thought they looked like a piece of high-tech jewelry that had slipped off an earlobe. They don't go in your ear. They don't sit over your ear. They basically just cuff onto the side of your cartilage like a futuristic earring. It’s a weird design choice. But after putting them through their paces in the real world—from loud coffee shops to quiet office environments—it’s clear that Bose isn't just trying to be different for the sake of it.
They’re solving a very specific problem.
Standard noise-canceling buds are great until you realize you've been shouting at the barista because you can't hear your own voice. Or worse, you almost get flattened by a silent electric car while jogging. These earbuds are the antithesis of the "noise-canceling bubble." They are designed to let the world in while still pumping high-quality audio into your head. It's a tricky balance to strike without sounding like a tinny radio from 1994.
The Design Is Basically a Hug for Your Ear
The first thing you’ll notice about the Bose Ultra Open Earbuds is the flex arm. It’s a soft, silicone-coated wire that connects the speaker housing to the battery barrel. You sort of hook the speaker part into the inner bowl of your ear and then wrap the barrel around the back. It feels secure. Surprisingly secure. I’ve gone on three-mile runs and done high-intensity interval training in these, and they didn't budge. Unlike the traditional "buds" that rely on a tight seal in your ear canal—which can get sweaty and itchy—these just sit there.
There's no pressure.
Most people struggle with "ear fatigue" after two hours of wearing AirPods Pro or Sony WF-1000XM5s. With the Ultra Open, you genuinely forget you’re wearing them. I’ve actually walked into the shower with them still on because my brain stopped registering their weight. That’s the "lifestyle" play here. You aren't meant to take them in and out all day. You just leave them on.

No, They Aren't Bone Conduction
A lot of folks get these confused with bone conduction tech like Shokz. It’s a fair mistake. But the Bose Ultra Open Earbuds actually use specialized air conduction. Bose calls it "OpenAudio" technology. Essentially, it’s a tiny, highly directional speaker that beams sound directly into your ear canal from a slight distance.
The engineering magic here is the phase cancellation. To prevent everyone on the bus from hearing your embarrassing 80s pop playlist, the earbuds project a second signal that cancels out the sound leaking into the environment. It isn't 100% silent to outsiders if you’re cranking the volume to max in a library, but at 50-60% volume, the person sitting next to you won't hear a thing.
Sound Quality and the Immersive Audio Factor
If you’re an audiophile, you’re probably skeptical. How can something with zero seal produce decent bass? Well, it won't beat a pair of over-ear Bose QuietComfort headphones for low-end thump. It just won't. Physics is a stubborn thing. However, for an open-ear design, the bass is shockingly present. It’s punchy rather than vibrating.
The real star is the Immersive Audio mode.
Bose uses an onboard IMU (inertial measurement unit) to track your head movements. When you turn on "Still" mode, the audio stays fixed in space. If you turn your head to the left, the sound feels like it’s coming from a speaker sitting right in front of your face. It adds a layer of depth that masks the fact that the drivers are tiny. Is it a gimmick? Sorta. But it makes podcasts sound like the person is standing in the room with you, which is a lot more natural than having the voice piped directly into the center of your skull.

The Connectivity Reality Check
Let's talk specs for a second because this is where some people get annoyed. These buds support Snapdragon Sound and aptX Adaptive. If you have a high-end Android phone, you’re getting great bitrates. If you’re an iPhone user, you’re stuck with AAC. It still sounds good, but you aren't getting that "lossless-adjacent" experience.
Also, there is no multipoint pairing at launch.
Update: Bose eventually pushed a firmware update to address this, but it’s still a bit clunky compared to the seamless switching you get with Apple or Google’s ecosystems. You have to use the Bose Music app to manage your connections. It works, but it’s an extra step that feels a bit "last gen" for a product that costs $299.
Who Are the Bose Ultra Open Earbuds Actually For?
If you spend your day in an office where people are constantly popping by your desk, these are a godsend. You can have your background lo-fi beats playing and still hear your boss asking about the quarterly reports without reaching for a "Transparency Mode" button.
They are also for:
- Outdoor Runners: Being able to hear a bike bell or a dog barking behind you is literally a lifesaver.
- Parents: You can listen to a true-crime podcast while making sure the kids aren't dismantling the living room in the next room.
- People with "Ear Sensitivity": If you hate the feeling of silicone tips jammed into your ear, this is the best alternative on the market.
However, if you’re a frequent flyer? Forget it. The Bose Ultra Open Earbuds are useless on an airplane. The engine drone will completely wash out your audio. These are not a replacement for your noise-canceling cans; they are a supplement to them.
Real World Battery Performance
Bose claims about 7.5 hours of play time. In my testing, that’s fairly accurate—if you leave Immersive Audio off. If you turn on the head-tracking spatial audio, that battery life drops significantly, closer to 4.5 or 5 hours.
The case gives you another 19 hours or so.
The case itself is a bit of a mixed bag. It’s tall and thin, which fits well in a pocket, but it lacks wireless charging. For $300, that’s a tough pill to swallow. You have to plug in a USB-C cable like it’s 2019. It’s not a dealbreaker, but it’s one of those "really, Bose?" moments.
Understanding the Competition
You’ve got the Sony LinkBuds (the ones with the actual hole in the middle) and the Huawei FreeClip. The Sonys are cheaper but can be uncomfortable for some ear shapes because they are rigid. The Huawei clips are very similar in form factor but harder to find in the US and don't have the same "Bose sound signature."
Bose wins on the "vibe." The audio feels fuller and the build quality of the flex arm feels like it can take a beating.
Getting the Most Out of Your Purchase
If you decide to pick these up, don't just use them out of the box. Open the Bose Music app. The default EQ is a bit flat because Bose is trying to play it safe with the open-air design. I usually bump the bass up by +4 and the treble by +2 to give it that extra sparkle.
Also, pay attention to the "Auto Volume" feature. It’s supposed to adjust your music based on the ambient noise around you. It’s hit or miss. Sometimes it overcompensates when a bus drives by, making the music uncomfortably loud. I usually keep it off and just use the physical buttons on the barrels.
Speaking of buttons—thank God they aren't touch-sensitive. Touch controls on earbuds are the worst, especially if you have long hair or wear a hat. These have actual, tactile buttons on the top of the battery barrels. They work every time, even with gloves on.
The Verdict on the "Clip-On" Future
The Bose Ultra Open Earbuds represent a shift in how we think about "wearables." We are moving away from devices we "put on for a task" and toward devices we "wear as part of our person."
They aren't perfect. They are expensive. They don't have wireless charging. But they are the first pair of open earbuds that I actually enjoy listening to. They don't feel like a compromise. They feel like a new category. If you value situational awareness and all-day comfort over total silence, these are currently the gold standard.
Actionable Next Steps:
- Check your ear shape: While these are "one size fits most," if you have extremely thick or very thin outer ear cartilage, try to test a pair at a retail store first to ensure the "grip" is comfortable.
- Update the firmware immediately: Out of the box, you might experience some connection drops. The latest Bose firmware stabilizes the Bluetooth 5.3 connection significantly.
- Manage your expectations: Do not buy these for the gym if your gym plays loud "club music" over the speakers. You’ll end up in a volume war with the gym's sound system that you will lose.
- Use them for calls: The mic quality is surprisingly good because the microphones are positioned away from the wind-drag of the ear canal. They make for an excellent work-from-home headset.
