Best Open-Ear Earbuds That Don't Fall Out (2026): OpenRock S2 Review
A close look at OpenRock's lightweight, secure-fit open-ear sport earbuds
OpenRock S2 Open-Ear Air Conduction Sport Earbuds
A light, stability-first open-ear earbud with real Hi-Res audio support. If you want secure buds that keep your ears open while you work out, it's an easy one to recommend.
- Hook-clip, pressure-diffusion fit spreads the weight across 8 contact points, so they sit tight while you move
- At 7g each, there's barely any weight to bounce loose
- Triple-sweatproof with IPX5 water resistance, so workouts and outdoor sessions aren't a worry
- LDAC and Hi-Res Audio support plus BassDirect bass, which you don't always get at this price
- Bluetooth 6.0 with multipoint, so they hold a link to two devices at once
- An open-ear build leaks a bit of sound and lets ambient noise in, so skip these if you need real isolation
- OpenRock doesn't list battery life for this model, so check the playtime first if that's a dealbreaker
- It's a single focused pick here, not a multi-brand shootout
If you want open-ear earbuds that won't slip out mid-run, the OpenRock S2 Open-Ear Air Conduction Sport Earbuds are the pair I'd point you to first. Instead of one pressure point, the hook-clip fit spreads the weight across 8 contact spots, so they hold steady while you move and still leave your ears open to what's going on around you.
Here's the thing about open-ear buds. They sit just outside your ear canal rather than plugging it, which is great for awareness but tricky for staying put. The S2 leans on a pressure-diffusion fit and a tiny 7g body to deal with that. There's simply less weight bouncing around to work loose. Throw in triple-sweatproof IPX5 protection and a 4-mic wind-resistant build, and it's pretty clearly made with running and outdoor training in mind.
This is one honest pick based on what OpenRock actually lists, not a padded ranking. Below you'll find what the S2 does well, who it suits, and where it comes up short.
What to look for in Open-Ear Audio
Who it's for
These are for runners, gym regulars, and anyone training outdoors who wants buds that stay on without sealing off their ears. You'll still hear traffic, a teammate calling your name, or whatever's happening around you. The 7g weight, IPX5 sweat resistance, and 8-point fit are all about movement. If you'd rather have deep noise isolation for a loud train ride or a quiet office, a sealed in-ear pair will serve you better.
Frequently Asked Questions
Will the OpenRock S2 actually stay in during a run?
They're built with that in mind. The hook-clip, pressure-diffusion fit spreads weight across 8 contact points for a steadier hold, and the 7g body means there's hardly any weight to bounce loose. OpenRock pitches them for athletic, on-the-go use.
Can I hear my surroundings with these?
Yep, that's kind of the whole idea. They rest outside your ear canal instead of sealing it, so you stay aware of traffic, people, and what's around you. The trade-off is they leak a little sound and let ambient noise in, so they're not the pick when you need isolation.
Are they sweat- and water-resistant enough for the gym?
They are. The S2 is triple-sweatproof with an IPX5 rating, which handles sweat and splashes from workouts and outdoor sessions just fine. IPX5 isn't rated for submersion, though, so don't take them swimming.
Do they support high-quality audio?
They cover LDAC and Hi-Res Audio plus OpenRock's BassDirect bass tech, which is a nice touch for open-ear sport earbuds at this price. Just remember that any open-ear design gives up some isolation and low-end punch in exchange for awareness.
Can I connect them to my phone and laptop at the same time?
Yes. They run Bluetooth 6.0 with multipoint, so they hold a link to two devices at once and let you switch between them.
How much do the OpenRock S2 cost?
They're listed at $68.99, which lands them in the mid-range for open-ear sport earbuds while still bringing Hi-Res LDAC audio and a secure-fit build.
The bottom line
Want open-ear earbuds that stay put without plugging your ears? The OpenRock S2 is a smart, sensible buy at $68.99. The 8-point fit, 7g weight, and IPX5 sweat resistance are all geared for movement, and the LDAC Hi-Res audio is a genuine bonus at the price. Just go in clear-eyed: open-ear means you'll hear your surroundings, and they'll catch a little of your music too. That's the design, not a flaw.
