Using your Shokz OpenRun headphones is easy. First, turn on the headphones and pair them with your device via Bluetooth v5. The type - C charging port makes it convenient to charge the headphones. You can wear them by placing the angled transducers on your cheekbones for the best sound. When using them, you can enjoy 8 hours of talk or music, but remember to charge them regularly. Since they have an IP67 waterproof rating, they can handle sweat and short - term submersion in water. However, don't keep them underwater for longer than 0.5 hours. After using them, wipe them with a dry cloth. Store them in a cool and dry place when not in use. The dual noise - cancelling microphone works well in high - noise environments, so you can use them in any noisy place without worry.
