Using the Shokz OpenRun Pro is easy. Just pair it with your Bluetooth device and start enjoying music or taking calls. When working out, make sure it fits snugly on your head for the best experience. For calls, the dual noise - cancelling microphone will do the job, but try to speak clearly. To keep the battery in good shape, don't overcharge it. When you're done with a 5 - minute quick charge, you'll have enough power for a short workout. As for maintenance, since it has an IP55 rating, you can wipe it clean after a sweaty session or when it gets wet. But avoid submerging it in water. Keep it in a dry place when not in use, and it'll serve you well for a long time.
