If you're experiencing an issue where only one of the Skullcandy Indy Evo earbuds is playing audio, follow these steps to resolve the problem and get audio in both ears: 1. Place both earbuds in the charging case and ensure they are fully charged. 2. Remove both earbuds from the charging case. They should automatically turn on and enter pairing mode, indicated by LED lights flashing on both earbuds. 3. Go to the Bluetooth settings on your device (smartphone, tablet, or computer) and forget or remove the Indy Evo from the list of paired devices. 4. Turn off Bluetooth on your device, then turn it back on after a few seconds. 5. With both earbuds still flashing, indicating they are in pairing mode, find the Skullcandy Indy Evo in the list of available devices in your Bluetooth settings and connect to it. If the earbuds are still not playing audio in both ears, you may need to perform a factory reset: 1. Remove both earbuds from the charging case and turn them off by touching and holding the touch panels on both earbuds for 6 seconds. 2. Press and hold the touch panels on both earbuds for 10-12 seconds. You will see a sequence of red, blue, and pink LED lights, followed by the earbuds turning off. 3. Place both earbuds back in the charging case and close the lid. 4. Remove the earbuds from the charging case, and they should automatically turn on and enter pairing mode. 5. Repeat the process of removing the Indy Evo from your device's paired devices list, turning Bluetooth off and on, and connecting to the earbuds in your Bluetooth settings. After following these steps, both earbuds should be playing audio. If the issue persists, it may be a hardware problem, and you should contact Skullcandy's customer support for further assistance.
