There are so many ways to troubleshoot your left earbud not working.

I’m going to show you eight different solutions to your problem, starting with the easier solutions, followed by the more complicated ones. 

Solution 1: Wear Your Earbud Correctly

Before we get into the heavy troubleshooting, you should first ensure that you’re wearing your left earbud correctly.

If the earbuds do not sit snugly in your ear or are worn incorrectly, it could affect audio or mic quality.

Here’s how to make sure you’re wearing your earbuds correctly:

  1. Make sure the earbud rests gently in your ear canal.
  2. Slowly rotate your earbud until the ear tip completely seals the canal of your ear.
  3. The ear-tip wing should be tucked around your ear ridge.
  4. The ear-tip should feel comfortable and not feel squished.

Solution 2: Troubleshoot The Charging Pins

It’s possible that your left earbud is not broken; it’s just not charged fully.

When you place your earbud in the case, you need to make sure it’s lined up with the charging pins.

If not, your earbuds will be on and drain their batteries throughout the day.

Another thing to look out for is the charging pins getting stuck. Make sure the charging pins are not stuck by pushing on them.

If the charging pins are stuck, you can try using a needle nose plier to pull up the spring-loaded charging prong.

Just be careful not to damage the earbud. It may be best for a professional to do this.

To confirm that your left earbud is being properly charged, the corresponding LEDs should light up when you put the earbud in its charging case.

Solution 3: Try Out A Different App Or Media Type

If you can’t hear any music out of your left earbud, try switching to a video on Youtube.

The problem could be the app your using and not your Bose Quietcomfort left earbud not working.

The sound quality might vary depending on the type of media.

For example, podcasts and streaming music services like Spotify are cloud-based and may naturally sound distorted to you.

Try various types of media to see if the problem is associated with a specific application.

Tip: Audio problems could also result in an app that needs to be updated.  Make sure to update your media apps. You can do this at the Google Play Store or Apple App Store.

Solution 4: Resync Earbuds And Charging Case

  3. Take your earbuds out of the case. Your earbuds should now communicate with each other like they normally would.

Solution 6: Disable In-Ear Detection

The Bose earbud has an In-ear Detection feature that automatically plays or pauses audio based on if the earbud is in your ear or not.

Although this can be a useful option, it might negatively affect the audio quality in the left ear.

Many users have tested this and come to the conclusion that this option is why their left earbud stopped working.

To prevent this from happening, you should disable In-ear detection on your earbuds with these steps:

  1. Open up the Bose Music App on your device.
  2. Click or tap on the Settings Menu.
  3. Search for the Toggle In-Ear detection option.
