My music cuts out or my headphones do not
stay connected
When using a Forerunner 245 Music device connected to
headphones using Bluetooth technology, the signal is strongest
when there is a direct line of sight between the device and the
antenna on the headphones.
• If the signal passes through your body, you may experience
signal loss or your headphones may become disconnected.
• It is recommended to wear your headphones with the
antenna on the same side of your body as your
Forerunner 245 Music device.
• Since headphones vary by model, you can try moving the
watch to your other wrist.
