SSo-called bone conduction headphones are a runner’s best friend, allowing you to stay fully aware of the outside world while listening to motivational music. But the technology doesn’t produce decent bass, a problem that open-ear headphone maker Shokz believes it has solved with its latest OpenRun Pro 2.
A successor to the popular OpenRun Pro and OpenSwim series, the OpenRun Pro 2 costs £169 (€199 / $175 / AU$299) and is similar to most of its competitors, with bone conduction pods secured in front of the ears by two loops and a band that wraps around the back of the head.
What makes these headphones unique is that the pods have open-air speakers built into them, allowing music to be streamed towards the outer ear. Bone conduction The speakers vibrate your cheekbones to send sound directly to your inner ear, while open-air speakers handle the bass and the rest of the sound is sent to the listener via bone conduction.
They don’t deliver the skull-shaking bass of larger over-ear headphones, but the OpenRun Pro 2 sounds fuller and rounder than its predecessor, and won’t send thumping noises through your cheeks even at louder volumes. Instruments, drums, and vocals have more depth, making them especially great for podcasts and dance tracks. The Shokz smartphone app offers an equalizer to fine-tune the sound of the headphones, as well as other updates and adjustments.
But the open-air speakers block out a lot more background noise than traditional bone-conduction headphones, significantly reducing awareness of cars, cyclists, and other runners. They’re still far better than earbuds or other headphones, but the difference was noticeable when listening at moderate volumes while running.
Only at 50% volume will nearby people be able to hear the music a little better than regular bone conduction earphones – they’re less noticeable than cheaper earphones and aren’t loud enough to be an issue when running.

Bluetooth upgrade and comfortable fit
Another big upgrade from previous Shokz is support for Bluetooth 5.3 with multipoint, meaning you can connect two devices at the same time. This is especially useful if you want to connect to a running watch and a phone at the same time. You can even take a call while listening to music and lap guidance from the watch without stopping.
The headphones fit very well, with a nice balance between the front and back of the ears, and the back band is just the right amount of flexible, putting enough pressure on the sides of your head without being too restrictive. A mini version is also available for those who want a tighter fit.
The volume buttons are on the headphone body behind the right ear, and the multifunction button that controls playback is on the outside of the pod in front of the left ear. The microphone for calls is on the right pod and works well enough, although callers said my voice sounded a bit distant and quiet.
The battery lasts for 12 hours on a single charge and fully charges in about an hour via the USB-C port. The headphones are splash-resistant, so they’re fine for a sweaty run, but that doesn’t mean they’re safe to immerse in water.
Sustainability
Shokz claims that the batteries in the earbuds and case will retain at least 80% of their original capacity for 800 full charge cycles. Shokz does not offer trade-in, recycling or repair services, and the batteries cannot be replaced. The headphones do not contain any recycled materials, and the company has not released an environmental impact report.
price
The OpenRun Pro 2 costs £169 (€199 / $175 / AU$299).
By comparison, the Shokz OpenRun costs £130, the Suunto Wing costs £145, the Creative Outlier Free Pro+ costs £80 and the Bose Ultra Open earphones cost £250.
verdict
The OpenRun Pro 2 solves the bass-deficient issue of bone conduction headphones by adding open-air speakers that handle the bass.
They don’t deliver skull-shaking bass, but they deliver a rich sound that’s just as good as standard earphones, making them a marked improvement over previous earphones. The trade-off, however, is a slightly worse situational awareness at moderate volumes. This isn’t a deal-breaker for me, but if you like to listen to music loud while running, it might negate the point of buying bone conduction headphones.
The addition of Bluetooth multipoint, which lets you connect to two devices simultaneously, is a nice touch, as is the 12-hour battery life and the fact that charging is done via a standard USB-C cable rather than a proprietary port.
The Shokz are not cheap and are not suitable for general use as headphones, but the biggest problem is that they cannot be repaired and the battery is not replaceable, so they end up being disposable and lose a star.
Strong Points: Much rounder sound than bone conduction, open air recognition, splash proof, solid battery life, standard USB-C charging, Bluetooth multipoint, great for running.
Cons: They offer slightly less recognition than bone conduction alone, are expensive, don’t support high-quality Bluetooth audio formats, and are not repairable or have replaceable batteries.
