Using your Shokz OpenRun Mini headphones is easy. First, charge them using the Type - C charging port. Once charged, turn on the Bluetooth on your device and pair it with the headphones. Put the headphones on with the transducers on your cheekbones for the best sound. You can use them to listen to music or take calls. When working out, don't worry about sweat or a little water as they are IP67 waterproof. But avoid leaving them submerged for longer than 0.5 hours. To keep them in good condition, wipe them with a dry cloth after use. Store them in a cool, dry place. And if you're not using them for a long time, charge them every few months to keep the battery healthy.
