3.4. Fit Guide
To ensure optimal sound and comfort, it's important to choose the correct size and wear your OpenRun Pro 2 headphones properly.
- Use a flexible tape measure to measure from behind your left ear to behind your right ear, across the back of your head.
- If your measurement is 23.5 cm (9.25 inches) or more, the standard size is the best fit.
- If your measurement is less than 23.5 cm (9.25 inches), the mini size is the best fit.
- Your headphones should feel secure, with the transducers resting in front of your ears, not above them.
- The headband should sit comfortably along the back of your neck, not too high on your head. There should be a small gap between the headband and your head. If there is no space, the headphones are too small.
