The 30-Second Version
Bose's open-ear clip-ons are a comfort champion with sound that punches way above expectations. The weak mic and missing ANC are the trade-offs, but at the right price, they're a no-brainer for anyone who hates in-ear buds.
Overview
Look, if you hate the plugged-up feeling of in-ear buds, the Bose Ultra Open Earbuds might be exactly what you've been waiting for. They use a flexible clip that hugs your outer ear, leaving the canal completely free. That means you hear your music and the world around you at the same time—no transparency mode required. Comfort is off the charts, sitting in the 93rd percentile of our database. It's the kind of wear-all-day fit that makes you forget you're even wearing them.
Sound-wise, Bose pulled off something tricky. OpenAudio tech keeps the audio surprisingly private and rich, hitting the 85th percentile for sound—that's better than plenty of sealed buds. Add in spatial audio and rock-solid Bluetooth 5.3 connectivity, and you've got a package that feels more premium than the open-ear category typically offers. Just be ready for a wide price swing: we've seen them from $229 to $407, so shopping around pays off.
Performance
The highs here are really high. Comfort is simply best-in-class, and the audio is crisp and immersive, with solid bass oomph for an open design. Connectivity is a standout too, with zero dropouts in our testing. But the battery isn't groundbreaking—7.5 hours in the buds, 27 total—it's solid, just middle of the pack. The real low point is the mic. At the 55th percentile, it's average at best, and your voice gets washed out in any kind of background noise. And of course, ANC is nonexistent (that's the point), so don't expect any help against airplane drone.

Value & Pricing
There's a $200 gap between the cheapest and most expensive listings we found, which is wild. At $229, the Ultra Open Earbuds are a compelling buy for the comfort and unique awareness they offer. But if you're paying north of $350, you're venturing into flagship noise-canceling territory from Sony or Sennheiser, which outperform these on sound and calls. Grab them at the low end and you'll feel great about the purchase.
vs Competition
Most of the competition comes from sealed, ANC-equipped earbuds. The Sony WF-1000XM5 and Sennheiser Momentum True Wireless 4 deliver richer, more isolated audio and far better call quality. But they can't touch the Bose for all-day comfort and environmental awareness. The Samsung Galaxy Buds3 Pro sit somewhere in between, but if the open-ear design is what you're after, there's not really a direct rival that matches Bose's execution here.

Common Questions
Q: Do the Bose Ultra Open Earbuds support Auracast?
No, despite using Bluetooth 5.3, they do not support Auracast broadcasting features.
Q: Can I use these for running and workouts?
Absolutely. The flexible grip keeps them secure, and the IPX4 rating means sweat and light rain won't hurt them.
Q: Is the sound really private, or will people next to me hear it?
Bose's OpenAudio tech does a remarkable job keeping the sound contained. At normal volumes, someone right beside you might catch a faint leak, but it's far less than you'd expect from an open design.
Who Should Skip This
Skip these if you need clear phone calls on the go or any sort of noise isolation. The open design is a feature for awareness, but it means you hear everything around you, and your callers will too. If that's a dealbreaker, look at the Sony WF-1000XM5 or Sennheiser Momentum True Wireless 4 instead.
Verdict
Buy these if your top priority is staying connected to the world while enjoying music. They're perfect for runners, cyclists, office workers, or anyone who just can't stand the plugged-ear feeling. You won't win any phone call awards, but you'll be comfortable and aware, with audio that genuinely surprises.
