Using your Shokz OpenRun Pro headphones is a breeze. Just pair them with your Bluetooth device, and you're ready to go. When taking calls, make sure your voice is close to the dual noise - cancelling microphone for clear communication. For the best audio experience, adjust the headphones to fit your ears properly. Don't expose the headphones to extreme temperatures or humidity. When not in use, keep them in a dry place. Clean them regularly with a soft, dry cloth. Avoid using harsh chemicals as they can damage the headphones. If the battery runs low, use the provided charger for a quick boost. Remember, a 5 - minute charge gives you 1.5 hours of use. Happy listening and training!
