The proof
Performance
The 11mm ring driver is a clever piece of engineering. Mids and highs come through crisp and clear, and the sound lands in the 86th percentile in our database, which is genuinely impressive for an open design. But the bass is weak, and that's not a tuning choice, it's physics. You can't have an open ring and expect sub-bass rumble. The adaptive volume control is a nice touch that actually works, and the 3-minute quick charge giving you an hour of playback is clutch when you're running late.

vs Competition
The obvious comparison is the Apple AirPods Pro 3rd Generation, which gives you real ANC and much better bass for similar money, but you lose the open design and all-day comfort. The Nothing Buds 2 are a budget alternative with a more traditional fit and better bass, but they don't match the LinkBuds Open's comfort or connectivity. The Technics EAH-AZ100 is the dark horse here, with better sound overall but a bulkier fit. If you want the open ring design specifically, the LinkBuds Open are basically in a class of their own.

Price
Value & Pricing
At $228 to $240, these are priced like premium earbuds but deliver a very specific experience. If you want the open design, there's nothing else quite like them, and the comfort alone might justify the price. But if you're expecting AirPods Pro level sound isolation or bass, you're paying a lot for something these fundamentally can't do.

Overview
The Sony LinkBuds Open are for people who hate the feeling of being sealed off from the world. The open ring design means you hear your music and everything around you, which is either exactly what you want or completely pointless depending on your life. For all-day wear at a desk or walking around the city, these are some of the most comfortable earbuds we've tested. Just don't expect thumping bass or any real noise isolation.
Common Questions
Q: Do the LinkBuds Open have noise cancellation?
No, not really. They have some ANC features in the app, but the open ring design means sound gets in no matter what. If you want real noise cancellation, get the AirPods Pro or Sony's own WF-1000XM5.
Q: Can I use these for running or working out?
I wouldn't recommend it. The fit is comfortable for sitting and walking, but multiple owners report they get loose during vigorous movement. For workouts, get something with ear hooks or a tighter seal.
Q: How is the battery life?
About 8 hours on the buds and another 14 in the case, so 22 hours total. That's below average for true wireless earbuds in 2025, but the 3-minute quick charge giving you an hour of playback helps a lot.
Who Should Skip This
If you want thumping bass, real noise cancellation, or earbuds that stay put during a HIIT workout, these aren't it. Go get the AirPods Pro 3rd Generation for ANC and bass, or the Samsung Galaxy Buds3 Pro for a secure fit with better sound isolation. The LinkBuds Open are for people who prioritize comfort and awareness over everything else.
Verdict
The Sony LinkBuds Open are a niche product that nails their niche. If you want to hear your music and the world around you at the same time, and you value comfort above all else, these are the best open earbuds we've tested. If you want bass, noise cancellation, or a secure fit for workouts, look elsewhere. For the right person, these are a 9 out of 10. For everyone else, they're a 6.
