Using your Shokz OpenRun headphones is a breeze. First, turn on your device's Bluetooth and pair it with the headphones. Once paired, you can start playing your favorite music or taking calls. To adjust the volume, use the buttons on the side of the headphones. When you're done using them, make sure to charge them using the Type - C charging port. Since they are IP67 waterproof, you don't have to worry about sweat or a little water. But don't keep them submerged for longer than 0.5 hours. To maintain them, wipe them with a soft, dry cloth after use. Store them in a cool, dry place when not in use. Also, if you're in a very noisy environment, the dual noise - cancelling microphone will help reduce background noise, but it's always good to be aware of your surroundings for safety.
