If the sound is coming only from one ear, the audio is not balanced. You can check this on your laptop or phone.

  1. Open Settings and then “Audio settings”.
  2. Navigate to the “External audio device/speaker” or “Audio balance” option.
  3.  Move the volume slider and adjust it in the center of the line.

3. Reconnect the Headphones

Sometimes, the problem arises due to a temporary bug. Hence, it can be solved by restarting or resetting the Bluetooth connection. Here is how to do it:

  1. On your phone or laptop, open the Bluetooth settings.
  2. Click on your Bose QuietComfort headphones in the list of paired devices.
  3. Next, hit the “Forget” or “Disconnect” button next to the device.
  4. Turn OFF Bluetooth on both devices.
  5. Restart your headphones and computer or mobile phone.
  6. Now, pair the devices again via Bluetooth and check the audio.

  2. Complete the setup process and log in.
  3. Go to the “Settings” and then “System” or “Updates”.
  4. Check for a recent update and download it.
  5. Once the update process is complete, restart both devices.

5. Change macOS Settings

A lot of users reported that this issue occurs when they connect the headphones to their macOS.

While the headphones work normally with iPhones and other devices. If you are also in the same situation, try the following fix:

  1. On your Macbook, go to the “Settings”.
  2. Open the “Sound Settings” and then scroll to select the “Input”.
  3. It will show you the list of available mics.
  4. Is your Bose QC 35 chosen as input? If yes, select a Mac microphone as input.
  5. The reason behind the issue is that your headphones are currently working as input mic.
  6. So, changing this setting will fix the problem.

6. Troubleshoot the Apps

In some cases, the problem arises only with certain apps. For example, some users noted that their headphones malfunction while working with Skype, Zoom, or some other application or software.

However, the device works normally and both ears give sound with other apps. This suggests that the issue is app-specific. Hence, you need to troubleshoot those apps or software.

EzoicFirstly, update the software or app. Secondly, uninstall the app, wait a few minutes, and reinstall it. Hopefully, this will work for you.

7. Reset Your Bose QC 35

Resetting is a promising way to troubleshoot the various issues on your device. Here is how do you reset your Bose QC 35:

  1. Turn OFF the headphones and wait for 30 seconds.
  2. Now, plug the device into a power outlet using the provided USB charger.
  3. After 5 seconds, disconnect the power cable from your headphones.
  4. Wait for 60 seconds before turning ON your headphones again.
  5. Now, they are reset and will function normally.

8. Fix the Halfway Point Issue

The headphones might have stuck in the halfway. They can connect both physically and wirelessly. A mechanical trigger has caused this issue.

It happens when you switch between wireless and wired modes. The solution is as follows:

  1. Take an AUX or audio cable and connect it to your headphones.
  2. Insert the other end of the cable into the audio jack on your phone or computer while playing an audio file.
  3. Now, check if the sound comes from both ears. Unplug the cable and pair the devices wirelessly.
  4. If the sound comes from both ears, you are good to go. If not, repeat the process again.
  5. Plug the audio cable, unplug it, and connect via Bluetooth.
  6. Repeating this two or three times will fix the halfway point issue.

9. Fix the Hardware Issues

A minor hardware issue can also create such problems. For example, the wiring may be loose or some internal wires have missed connection.

It can happen due to intense shakes, bumps, or falls. However, you can realign the wires by a simple trick:

  1. First of all, remove the ear pad or cushion from the earcup that is not producing sound.
  2. Also, remove the sticker so that the internal wiring is exposed.
  3. Take a small piece of paper or sticky notes. Fold it in a way that it becomes narrow and firm to fit in a tight space.
  4. Observe closely and locate the black plastic area in the upper right portion of the earcup.
  5. You will see copper wires in this area.
  6. Push the folded paper through the hole and press gently. Adjust the misaligned copper wire and remove the paper.
  7. Adjust the wires properly by repeating the process. Place the sticker and the cushion if both sides start working.

10. Contact Bose Support

The above-mentioned method is good for beginners if they want to fix the hardware issue at home. But, we don’t recommend proceeding further or opening your headphones.

Because this will exceed the warranty and there is a risk of damaging the device further. Hence, you must contact Bose customer support if the issue still exists.

EzoicThe company will help you in repairing or replacing the device if it is under warranty.
