If you hear music through your device but not through your headphones: 1. Go to your device settings and re-establish the Bluetooth connection. 2. Be sure to adjust the volume on your Bluetooth device accordingly. The headphones will emit one beep if they are turned off. 3. The app you are using on your device may affect playback timing. 4. Pause and turn on the music. This may fix the issue. 5. If the problem persists, turn off your headphones and turn them back on to re-establish a Bluetooth connection with your device. After the earbuds are paired and connected to the Bluetooth device, they will still enter Bluetooth pairing. Go to Bluetooth settings and look for "Epic Air R" or "Epic Air L" that is trying to pair with the device. Click and connect to the device. Once connected, unplug the earphone and forget about it. This will fix the reconnect issue.
