My music cuts out or my headphones won't
stay connected
When using a Forerunner music watch connected to
Bluetooth headphones, the signal is strongest when
there is a direct line of sight between the watch and the
antenna on the headphones.
y If the signal passes through your body, you may
experience signal loss or your headphones may
become disconnected.
y If you wear your Forerunner music watch on your
left wrist, you should make sure the headphone's
Bluetooth antenna is on your left ear.
y Since headphones vary by model, you can try
wearing the watch on your other wrist.
y If you are using metal or leather watch bands, you
can switch to silicone watch bands to improve
signal strength.
