Running with music in your ears without cutting yourself off from the world: that's the promise of open-ear earbuds, and Shokz has made it its specialty. After years spent popularizing bone conduction, the brand is taking on the true open-ear market head-on with the OpenFit 2. We wore them on the road, on the track and on long runs to judge one thing: can earbuds that leave your ears free really replace your in-ears for training?
Shokz OpenFit 2 Review: DualBoost Open-Ear Earbuds for €189
8.7/10
The essentials in 3 sentences
The OpenFit 2 delivers much richer sound than earlier open-ear models thanks to its DualBoost technology, with two speakers per ear, while keeping your ears fully open to your surroundings. Its soft ear hook holds flawlessly, even on fast runs, and its 11-hour battery life (48 hours with the case) covers the biggest training weeks. At 189 euros it doesn't come cheap, but it remains the open-ear benchmark if you want to run with music without shutting out the road.

Shokz OpenFit 2: the open-ear model that wants you to forget in-ears
Shokz has two distinct families. On one side, its signature bone conduction, which vibrates the bones of your skull, as on the excellent Shokz OpenRun Pro 2. On the other, air-conduction open-ear, where a small speaker projects sound toward your ear canal without ever blocking it. The OpenFit 2 belongs to the second category, and for a runner that technical choice has major consequences.
In practice, you clip a small module behind your ear, connected to a flexible arm coated in liquid silicone, and the audio capsule sits just in front of the ear canal without closing it. The result: you hear your playlist and, at the same time, the car coming up, the bike passing you, your training partner talking. When you train in the city or on open roads, that awareness of your surroundings isn't a gimmick. It's a safety issue.
RunMorph tip. If you mostly run on open roads or in the city, open-ear should be your default: keeping an ear on traffic beats all the subwoofers in the world. The OpenFit 2 is the pick for comfort and sound. If you prefer an even more stable fit and an ultra-light format for racing, compare it with our review of the bone-conduction Suunto Wing 2.

Sound: what DualBoost really changes
The main criticism of open-ear earbuds has always been the same: thin sound with no bass that dissolves as soon as there's wind or noise. That's exactly where the OpenFit 2 makes progress. With two speakers per ear, one dedicated to bass and one to treble, plus a new rectangular driver, the sound gains body. Vocals are clear, highs are present without harshness and, above all, the bass finally exists, which the previous generation sorely lacked.
Let's be clear-eyed: open-ear earbuds will never match a good noise-cancelling in-ear for pure sound quality or immersion. The sound stays open, shared with your surroundings, and loses some of its substance once traffic picks up. But for training music or a podcast on an easy run, the level is more than enough, and the safety trade-off is worth it. The international consensus among testers ranks the OpenFit 2 among the best open-ear models of the moment for audio.

Who are the Shokz OpenFit 2 for?
Urban and road runners
They're the obvious target. In the city, hearing cars, bikes and other pedestrians is non-negotiable. The OpenFit 2 gives you your music without ever cutting you off from danger. For everyday running on open roads, it's hard to do better.
Long-run fans
With 11 hours of battery life and comfort that makes you forget you're wearing them, the OpenFit 2 handles the biggest runs without any pressure point in the ear canal. Over three hours of running, your ears don't heat up or get tired.
Runners who switch between sport and daily life
Bluetooth multipoint lets you switch from your phone to your computer without fiddling. The OpenFit 2 fits into an interval session just as easily as an office day or a video call.
Hold, comfort and water resistance in real conditions
This is probably the OpenFit 2's best feature. The soft hook hugs your ear and doesn't move, even on flying 200-meter repeats or fast downhills. We never had to readjust it mid-run, and it sits under sunglasses without conflict. The liquid silicone coating stays pleasant hour after hour, without the hot spot in-ears sometimes cause.
On durability, the IP55 rating shrugs off heavy sweat and steady rain. That's the expected level for running, but keep in mind it isn't swim-proof: skip the pool and the shower. For running in all weather, it's robust.
OpenFit 2 vs OpenRun Pro 2 vs Suunto Wing 2: the comparison
Three sports headphones, three technologies. The OpenFit 2 bets on air conduction and richer sound. The OpenRun Pro 2 sticks with bone conduction in an ultra-stable neckband format. The Suunto Wing 2 pushes bone conduction toward ultra distances with its external battery. Here's how they stack up.
| Model | Technology | Battery life | Water resistance | Price |
|---|---|---|---|---|
| Shokz OpenFit 2 | Air-conduction open-ear | 11 h (48 h) | IP55 | 189 euros |
| Shokz OpenRun Pro 2 | Bone conduction | 12 h | IP55 | 179 euros |
| Suunto Wing 2 | Bone conduction | 30 h total | IP55 | 199 euros |
The verdict depends on how you use them. For sound quality and everyday comfort, the OpenFit 2 has the edge. For a neckband hold that never moves, the OpenRun Pro 2 remains a safe bet. And for ultras or expeditions, the Suunto Wing 2's battery life makes the difference. Either way, if you also train by heart rate, good earbuds pair perfectly with a reliable chest strap like the Polar H10.
How to fit the OpenFit 2 into your RunMorph training plan
Good earbuds won't raise your maximal aerobic speed, but they change the quality of your sessions. On easy runs, music helps you hold a slow pace without getting bored. On long runs, a podcast makes the kilometers feel lighter. And because the OpenFit 2 leaves your ears open, you can follow audio cues from your watch or a training partner without ever taking anything out.
Structure your sessions, not just your playlist. Motivation alone won't make you progress: you need a framework. The RunMorph training plans turn your runs into calibrated sessions, from recovery runs to intervals, so you improve without getting injured. Put on your music, start today's session and let the plan manage the intensity.
The RunMorph Coach verdict
The OpenFit 2 is the most polished open-ear model Shokz has ever released: finally convincing sound, flawless hold and battery life that never lets you down, all without ever cutting you off from the road. It's expensive and won't replace an in-ear for pure isolation, but for runners who want music safely, it's an excellent choice. We give it 8.7/10, docking a few tenths mainly for the price.
Key takeaways for your training
- Free ears: safety on open roads, the number one argument for open-ear.
- DualBoost sound: bass you can finally hear, a real leap over classic open-ear models.
- Perfect hold: the soft hook doesn't move, even during fast intervals.
- 11 h battery life: 48 h with the case, enough for the biggest weeks.
- IP55 for running: resists sweat and rain, but not the pool.
