Shokz OpenRun Pro 2 review: bringing bass to bone conduction headphones

New running headphones combine bone conduction and open-air speakers for more rounded sound So-called bone conduction headphones are a runner’s best friend, allowing you to be fully aware of the outside world while you listen to your motivational tunes. But the technology simply can’t generate decent bass – a problem that the open-ear headphone firm Shokz thinks it has solved with its latest OpenRun Pro 2. The follow-up to the popular OpenRun Pro and OpenSwim lines, the OpenRun Pro 2 cost £169 (€199/$175/A$299) and resemble most competitors, with bone conduction pods held in place in front of the ear by two loops and a band that runs behind your head. Water resistance: IP55 (spray resistant) Connectivity: Bluetooth 5.3 (SBC) Battery life: 12h Dimensions: 30.9 x 21.7 x 24.3mm Weight: 30.3g Drivers: Air and bone conduction Charging: USB-C
