Using your Shokz OpenRun headphones is easy. First, charge them via the Type - C port. Turn them on and pair with your device using Bluetooth v5. Wear them on your cheekbones for the best sound. When you're done, turn them off to save battery. For workouts, don't worry about sweat or a little water as they're IP67 waterproof. But don't keep them submerged longer than 0.5 hours in 1 - meter - deep water. Clean them with a soft, dry cloth. Store them in a cool, dry place. The dual noise - cancelling microphone works well in noisy areas, so you can enjoy clear calls and music no matter how intense your exercise is.
