Using the P3 headset is easy. First, turn on the Bluetooth function on your device and pair it with the headset. You can then start gaming, listening to music, or making calls. When making calls, make sure the microphone is close to your mouth for clear sound. As for maintenance, keep the headset in a dry place when not in use. Clean it gently with a soft cloth from time to time to remove dust. Avoid dropping or subjecting it to strong impacts as it may affect its performance. With proper use and care, your P3 headset will serve you well for a long time.
