Basic Troubleshooting
Basic troubleshooting helps fix common problems quickly. Start with simple checks before trying complex solutions. These steps often solve the issue of the left earbud not working. Follow each step carefully to bring your Bose QuietComfort earbuds back to life.
Check Battery Level
Low battery can stop the left earbud from working. Place both earbuds in the charging case. Look for the charging light to confirm they are charging. Wait at least 15 minutes before testing again. Ensure the charging case also has enough power.
Reconnect Bluetooth
Bluetooth connection issues may cause sound loss. Turn off Bluetooth on your device. Wait a few seconds, then turn it back on. Remove the Bose earbuds from the device’s paired list. Pair the earbuds again as if new. This refreshes the connection and often fixes audio problems.
Clean The Earbud
Dirt and earwax block sound from the left earbud. Use a soft, dry cloth to clean the mesh and edges. Avoid using water or sharp tools. Gently remove any debris that might block sound. Clean regularly to keep earbuds working well.
