Why Are My Bose QC 35 Headphones Not Working? Troubleshooting Tips

Having your Bose QC 35 headphones mysteriously stop working can be quite frustrating. However, there are a variety of reasons why these headphones might be malfunctioning, and a series of troubleshooting steps you can try to resolve the issue.

Battery Issues

One of the most common causes of these headphones stopping work is a battery issue. Ensure that the headphones are fully charged. If the battery is exhausted, your headphones won’t function. Charge the headphones for a sufficient time and try turning them on again.

Bluetooth Connection

If you are using the headphones wirelessly, check if they are still connected to your device. Sometimes, the connection might break or needs to be reestablished. In your device's Bluetooth settings, disconnect and then reconnect the headphones.

Software/Firmware Update

Headphones may require a firmware update to function properly. Check the Bose Connect app to see if there are any available updates for your headphones. A software update might resolve any bugs or issues causing the malfunction.

Reset the Headphones

If the above methods don’t work, try resetting your Bose QC 35 headphones. Turn them off and press and hold the power button for approximately 10 seconds until you hear a confirmation beep. This can sometimes reset the internal systems and resolve any connectivity issues.

Physical Damage

Carefully inspect the headphones for any physical damage, especially around the charging port and ear cups. Any looseness or wear in these areas might be leading to connection problems.

Audio Source Issues

To rule out problems with your device, test the headphones with another audio source. Insert the headphones into another device and see if they work. If you still don’t get any sound from the original device, it might point to a problem with that device’s audio output.

Faulty Components

If none of the above steps result in sound or functionality, there might be an internal hardware issue. Contact Bose customer support for assistance. Alternatively, take the headphones to a certified repair center to have a professional diagnose and fix the problem.

Providing more detailed information about the symptoms, such as no sound or the unit not powering on, can offer more specific advice. It’s always a good idea to follow each step slowly and methodically to ensure you address every possible cause of the malfunction.
