My music cuts out or my headphones won't stay connected When using a D2 Mach 1 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. • If the signal passes through your body, you may experience signal loss or your headphones may become disconnected. • If you wear your D2 Mach 1 watch on your left wrist, you should make sure the headphone's Bluetooth antenna is on your left ear. • Since headphones vary by model, you can try wearing the watch on your other wrist. • If you are using metal or leather watch bands, you can switch to silicone watch bands to improve signal strength.
