HEADPHONE ANTENNA WHICH IS LOCATED IN THE CONTROL. Your body
is 80% water. Water blocks low power radio signal like Bluetooth. In
the absence of nearby ceilings for signal bounce, your body can block
the signal between the music device and the headphones. When
outdoors or at the gym the use of armbands or wrist-worn music
players are recommended. Having your music player in your pants
pocket below waist level may produce varied results as your body can
get between the music device & headphones.
