Shokz OpenRun Air 2 Review: My Last Complaint Is Finally Fixed

You’ll spot Shokz headphones on plenty of runners out on the road. I’m one of them — I’ve gone through several Shokz models myself, starting with the original OpenMove.

This time, Shokz — a pioneer in open-ear headphones — sent me their newest model, the OpenRun Air 2, to review.

It’s a bone-conduction headset that launched on September 16, 2026, priced at ¥19,880 (tax included).

What I most wanted to know was how well it holds up to sweat and rain. My old OpenRun had repeated charging problems, and I had to get it replaced under warranty more than once. This review focuses on what’s changed on that front.

By the end of this review, you’ll know what’s improved over the original OpenRun, how well it stands up to sweat and rain, and how to choose between the OpenRun, OpenRun Pro 2, and this new Air 2.

What’s New in the OpenRun Air 2 vs the Original OpenRun

As the name suggests, the OpenRun Air 2 is a ground-up redesign built on the original OpenRun. Here’s what’s changed.

The water and dust resistance rating stays at IP67, the same as the original OpenRun. The rating itself hasn’t changed, but as I’ll cover below, the charging port design has.

Charging and Power Issues: What Changed in the Air 2

This was the thing I most wanted to check with the OpenRun Air 2. A lot of people search for phrases like “Shokz won’t charge” or “OpenRun won’t turn on” — and I’ve been there myself.

What Happened With My Old OpenRun

I bought my original OpenRun myself, and over time it developed charging problems and would sometimes fail to power on. Since it was still under the 2-year warranty, Shokz replaced it for free each time.

I can’t say for certain what caused it, but I suspect sweat and rain were behind it. I mostly used it for running, and in summer the unit would get pretty soaked with sweat.

A Waterproof USB-C Port With a Sealed Cover

The OpenRun Air 2 charges through a waterproof USB-C port. The port itself is covered by a silicone flap that you only lift when you need to charge it. My old OpenRun, by contrast, used exposed magnetic charging contacts.

Shokz instructs users to make sure the charging port is completely dry before plugging in — which suggests that charging while it’s still wet is a common cause of problems.

After a run, it seems best to rinse off the sweat with water, dry the headphones thoroughly, and confirm the port is dry before charging.

The IP67 rating means you can rinse it off with water. As Shokz notes, though, that water resistance isn’t permanent — it gradually degrades with use. The headphones aren’t designed for swimming or underwater use.

A Lighter, More Stable Fit

The OpenRun Air 2 is more than 9% smaller than the original OpenRun, and you can feel the difference the moment you pick it up and put it on. See the spec table above for the exact weights.

The redesigned ear hooks follow the natural curve of your ear to distribute pressure evenly. The one-piece neckband shifts the center of gravity forward, which Shokz says helps reduce bounce when running, jumping, or turning your head.

The frame is made from nitinol, a durable nickel-titanium shape-memory alloy.

Because bone-conduction headphones don’t cover your ear canal, you can still hear cars and cyclists around you while running. They also don’t trap heat inside your ear during long wears, meaning less discomfort — a real advantage for running.

How to Choose Between Standard and Mini Sizes

The OpenRun Air 2 comes in Standard and Mini sizes. Use a tape measure to measure from behind one ear, around the back of your head, to behind the other ear.

I’d always found the Standard size a bit large in past models, but with the Air 2, the Standard size fit me perfectly.

It seems like Standard is aimed more at men and Mini more at women, based on the sizing.

Since bone-conduction headphones sit below your temples, they don’t interfere much with glasses or sunglasses. They also work fine alongside hats and visors.

Sound Quality and Sound Leakage

The OpenRun Air 2 uses a bone-conduction driver called PremiumPitch 3.0™. Its all-metal dual-coil, dual-lead design is said to improve bass and mid-to-high frequency reproduction over the original OpenRun.

You can switch between four preset EQ modes and two custom EQ modes in the Shokz app.

When I’m running outdoors, I’d rather hear my surroundings than focus on music, so I don’t notice small differences in bone-conduction sound quality all that much. In quiet settings you can feel the characteristic vibration if you touch the unit, but I never noticed it while actually running.

As for sound leakage, it’s never completely eliminated with bone-conduction headphones by design. Turn the volume up and people nearby may be able to hear it. It’s safer to keep the volume low in quiet places like trains.

Calls and Microphone Performance

The OpenRun Air 2 has dual microphones with AI noise reduction. Shokz says simulations modeled on busy intersections confirmed better wind-noise reduction and signal-to-noise ratio than the original OpenRun.

You can use it for video calls while running or walking, too. I occasionally use OpenRun models for online meetings myself. The call quality isn’t outstanding, but it’s perfectly usable for conversation.

10-Hour Battery Life With Fast Charging

Battery life is rated at up to 10 hours, a 25% jump from the original OpenRun’s 8 hours. Even someone running a 5-hour marathon can cover the trip there, the race itself, and the trip back on a single charge.

It also supports fast charging — just 5 minutes gets you up to 2 hours of playtime, and a full charge takes about 60 minutes. So even if you forget to charge it the night before, a quick top-up while you get ready is enough to cover your run.

Bluetooth 6.0 and the Shokz App

The OpenRun Air 2 supports Bluetooth 6.0 and Bluetooth multipoint, letting you connect two devices at once. Pair it with both your phone and computer, and you can switch between them without re-pairing.

The Shokz app lets you switch EQ modes, customize what the physical buttons do, play a sound to help you find the headphones, and update the firmware.

Using the Physical Buttons

The OpenRun Air 2 is controlled with physical buttons. The multi-function button and volume buttons are separate, so it’s hard to hit the wrong one even mid-run. Adjusting volume between different sources is fiddly on touch-control earbuds, but physical buttons make it reliable.

I’ve found physical buttons especially useful while running, since touch controls tend to misfire more often.

Who Should Buy the OpenRun Air 2 (and Who Shouldn’t)

OpenRun Air 2 vs OpenRun vs OpenRun Pro 2: Which Should You Choose?

The biggest differences between the OpenRun Air 2 and OpenRun Pro 2 are water resistance and sound architecture. The Pro 2 combines bone conduction with air conduction in its DualPitch™ system for better sound, but it’s only rated IP55 for water resistance.

If you like to rinse your headphones under the tap after a run, the IP67-rated OpenRun Air 2 gives you more peace of mind. It’s the better choice if durability against sweat and rain matters most to you.

Compared to the current OpenRun, the Air 2 is smaller and brings upgrades across the board — battery, Bluetooth, and charging port. With only a ¥2,000 price difference, there’s little reason not to go with the Air 2 if you’re buying today.

Where to Buy the OpenRun Air 2

The OpenRun Air 2 launched on September 16, 2026, priced at ¥19,880 (tax included), in Black and Ice Blue. It’s available through the official Shokz online store.

Prices sometimes drop below MSRP during sales, so it’s worth checking the current price before you buy.

Summary

I’ve been through several Shokz headphones since my original OpenMove, including some failures along the way. From that experience, the OpenRun Air 2 feels like a model that specifically addresses the charging issues that used to cause the most breakdowns. Shokz confirmed that added protection around the charging area, plus regularly cleaning it after use, are the keys to keeping that water resistance intact.
