You can turn the Heart Rate sensor off and still use the headphones for audio by placing your finger on the right earpiece for 3-4 seconds. You will hear an audio prompt stating, “Heart Rate disconnected” which will turn the Heart Rate sensor off. If you wish to turn the sensor back on, simply place your finger on the RIGHT earpiece again for 3-4 seconds until you hear the voice prompt stating that the Heart Rate sensor has been turned back on.
