## What reviewers say

**Shokz OpenRun Pro 2** — Three whitelisted hands-on testers (SoundGuys, TechRadar, What Hi-Fi) agree the OpenRun Pro 2 are among the best bone-conduction headphones for runners: lightweight (~30g), stable, comfortable, and aware of surroundings, with a 12-hour battery and USB-C fast charging (5 min = 2.5h). They split sharply on sound quality, and none published lab measurements (SoundGuys notes its Bruel & Kjaer 5128 rig cannot accurately measure bone-conduction frequency response). (3 sourced reviews.)
