Bose Ultra Open
Bose Immersive Spatial Audio와 OpenAudio 기술로 오픈형 디자인임에도 사적이고 풍부한 사운드를 구현하며, 이어버드 7.5시간, 케이스 포함 19.5시간 배터리와 10분 급속 충전으로 2시간 사용이 가능합니다. 유연한 조인트 그립이 6g의 초경량 본체를 귀에 안정적으로 고정해 장시간 착용에도 편안하며, IPX4 방수로 운동 시 땀을 견딥니다. 통화 품질은 56.4점으로 아쉽지만, 야외 러닝이나 출퇴근 중 주변 소리 인지가 중요한 사용자에게 최적화된 이어버드입니다.
Snapshot
The 30-Second Version
These are the most comfortable open-ear buds out there, with surprisingly clear sound and killer awareness. Just don't buy them for phone calls or rumbling bass.
Pros & Cons
Pros
- Incredibly comfortable, they practically vanish on your ears after a few minutes 99th
- Sound is clear and surprisingly private despite the open design 93th
- Awareness of surroundings is a game-changer for walking, working, or travel 91th
- Battery life easily lasts a full workday and then some 79th
Cons
- Call quality is disappointing, your voice sounds muffled and distant
- Bass lacks punch and depth compared to sealed earbuds
- Fit is hit-or-miss; the clip-on design may not grip all ear shapes
- Pricey for what you get, especially at the high end of the range

The proof
Performance
We were genuinely surprised by how good the sound is. At the 91st percentile in our database, it's crisp, detailed, and the Immersive Audio mode gives movies a fun, spatial kick. The comfort is elite (93rd percentile) — you'll forget you're wearing them. Battery life is solid, easily lasting a workday. On the flip side, the mic performance (55th percentile) is a slog. Your voice comes across muffled, and the earbuds struggle in anything noisier than a quiet room, making them a poor choice for calls.

vs Competition
If you need strong ANC and reliable call quality, skip these and look at the Sony WF-1000XM5 or Sennheiser Momentum True Wireless 4. Both crush the Bose in noise isolation and voice clarity. Samsung's Galaxy Buds3 Pro are a better fit if you're deep in the Samsung ecosystem. But none of those offer open-ear awareness with jewelry-like clip-on comfort. For a cheaper open-ear design, Shokz OpenDots ONE exist, but their sound fidelity can't match what Bose pulls off here.

Price
Value & Pricing
Value depends heavily on the price you find. We're seeing a wild $152 spread across vendors. At $227 from Amazon, they're a decent buy if open-ear awareness is your priority. At $299 or the absurd $379 some stores list, you're in flagship ANC territory — and these can't compete there. Grab them below $250 or wait.

Overview
The Bose Ultra Open Earbuds are the most comfortable open-ear buds we've ever tested, and they pull off a neat trick: rich, private audio while keeping you totally aware of your environment. But there's a big catch — call quality is downright mediocre, and if you crave deep bass or noise isolation, you'll feel let down. These are purpose-built for casual listening and all-day wear, not for powering through a loud office or taking important calls.
Common Questions
Q: Are they any good for phone calls?
Honestly, no. The mics pick up your voice but it sounds processed and tinny, and they struggle in anything but quiet rooms. Look at the Sony WF-1000XM5 if calls matter.
Q: Can people around me hear what I'm listening to?
At moderate volumes, Bose's OpenAudio tech keeps the sound mostly private. Crank it up and someone sitting next to you might catch faint audio, but it's far less leakage than you'd expect from an open design.
Q: Will they stay put during a workout?
The IPX4 rating handles sweat, and the lightweight clip-on is secure for casual exercise. But during high-impact movement like sprints or box jumps, the fit can loosen on some ear shapes. For pure gym use, a true in-ear sports bud is more reliable.
Who Should Skip This
If you're looking for a single earbud that nails calls, heavy bass, and noise isolation, this isn't it. Grab the Sony WF-1000XM5 or Sennheiser Momentum True Wireless 4 instead — both beat the Bose in everything except open-ear awareness and all-day comfort.
Verdict
The Bose Ultra Open Earbuds are the best open-ear, all-day-comfort buds you can buy right now, as long as you accept their Achilles' heel: calls are a letdown and bass is polite. If you want a stylish, awareness-first audio companion for music and podcasts in quiet places, they're a joy. If you need one earbud to do it all, look elsewhere.
