Reasons: Bluetooth Earbuds When Only One Side Works

If your  earbuds stop working right side or left side , Instead of jumping straight  into technical fixes.

  • Start by identifying whether the issue originates from your earbuds or your source device to effectively troubleshoot and ensure uninterrupted audio performance

Here are some major reasons for Bluetooth earbuds only one side working:

  • Insufficient Battery: One frequently overlooked cause of a single earbud not working is that the earbuds have run out of battery. To address this, place them back in the earbud case, charge them for approximately 20 minutes, and then recheck their operation

  • Bluetooth connectivity: :Double check that your Bluetooth devices are set up correctly; sometimes, one earbud might be disabled and simply requires re-establishing connectivity. Check for basic errors like having Bluetooth turned off.

  • Outdated Drivers: For certain smartphones, like iPhones, it’s crucial to keep drivers updated for compatibility with contemporary technologies and updated OS models.

  • Broken Pair: Inspect malfunctioned earbud closely for physical damages or check for water damage.. If one pair is broken, replacing them can resolve the issue of one side of the headphones not working.

  • Compatibility Issues: Incompatibility between your earbud brand and smartphone can cause errors, resulting in one earbud not working.

  • Multiple  Connections: Having too many Bluetooth devices connected to the smartphone may interfere with earbud functionality.

  • Dust and grime: can lead to a Bluetooth earbud producing no sound. Regularly cleaning your earbuds is essential to remove gunk, wax, dirt, and debris

How To Fix: If one side not working on Bluetooth earbuds

When it comes to Bluetooth earbuds, such as the T16 earbuds, it’s not uncommon to experience issues where only one side works—perhaps you find your left earbud not working while the right continues to function or vice versa

This could also happen with other models like the Nothing Ear (1), where one side may suddenly stop producing sound.

If you’re experiencing this issue with your T16 earbuds or any other model, once you’ve grasped the reasons as outlined earlier, it’s essential to move forward with targeted troubleshooting.

Test Another Pair of Earbuds With your Device

Prior diving into a comprehensive guide of troubleshooting Bluetooth earbuds with one side not working, connect another pair of earbuds to your device.

you may borrow it from a friend) —whether it’s a phone or computer.

If the substitute earbuds work perfectly fine, it indicates the issue is likely with the original earbuds. If the problem persists, the source device’s audio settings could be the culprit.

Test Another Source Device  With your Earbuds

If you don’t have another pair of earbuds handy, a quick thing to try is to connect your current set to a different source device.

For example, disconnect from your phone and then reconnect to your computer. If they work properly with the new source, the problem is not with the earbuds.

  • If one side earbud  is still not working, try a different application, like switching from Spotify to YouTube, to check if it’s a common cause related to specific audio sources or music players.

Low Battery Power

One side stops working can often be traced back to an issue of low charge. These wireless earphones come with built-in batteries that operate on the principle of requiring regular charging.


A common scenario I’ve encountered involves the charging case.

  • Since the earbuds often have different charge levels for each bud, it’s crucial to recharge them separately if one is using the other with sufficient power.

The situation where there’s no battery power left in one earbud means it won’t work.

  • To boost the performance and resolve this, one should first check the battery status through the accompanying earbud app or the indicator light.

Now, as someone who has frequently faced this trouble of one side not working on Bluetooth earbuds, I’ve learned that the quickest way to solve this low battery power issue is to charge the earbuds properly.

Insert the problematic earbud into the charging case and let it recharge for a few hours. This ensures that both earbuds receive equal power.

Additionally, always ensure the charging slot is clean before inserting the earbuds to avoid any charging issues.

Stereo/Mono Audio Settings

A crucial aspect often overlooked: STEREO/MONO AUDIO SETTINGS.

Most pairs of earbuds are designed to use together, but with the latest models, you can extract just one earbud from the case, and the buds will automatically detect they are in use and switch between stereo and mono sound modes.

This feature enables the earbuds to adapt to different listening preferences.

However, sometimes these devices require you to manually change the audio mode to produce sound in both earbuds.

  • If you find that only one earbud is working, it might be necessary to disable the mono mode and change the setting to stereo.

This way, you can hear from both earbuds. It’s a subtle yet effective tweak, often solving the problem without needing extensive technical know-how.

  • Go to your device’s audio settings.
  • Select Accessibility.
  • Tap sound balance.
  • Toggle the switch next to mono to disable it or select stereo mode.

Audio Imbalance

For one side not working on Bluetooth earbuds, this issue can often be traced back to the slider in the audio settings of your phone, PC, or tablet, which might not be positioned in the middle, leading to sound being heard in only one of the earbuds.

This can be particularly frustrating when you’re trying to enjoy music or a podcast and find that the audio is not evenly distributed.

Devices often have individual volume settings for each earbud, catering to personal preferences.

  • Sometimes, one earbud might be set to mute or a significantly decreased volume level, resulting in no sound from that side.

To adjust and Fix this audio imbalance, it’s usually quite easy. You just need to go into your device’s audio settings, often found in the accessibility menu. Here, there’s an option to modify the volume level for the right and left earbuds separately. This should restore sound to both sides.

Additionally, many modern earbuds support adjustments through an accompanying smartphone app, where you can balance the audio more precisely.

Damaged Earbud

If you’ve tried various tips to fix a Bluetooth earbud and nothing seems to work, it’s possible that the earbud is damaged.

  • Wireless earbuds are delicate and vulnerable to damage, especially when exposed to excess moisture or extreme temperatures.

This is mainly due to the batteries, which have a shorter lifespan, often not more than two years.

Many companies manufacture these earbuds with non-replaceable batteries. In such cases, the only solution might be to replace the earbud entirely.

Update the Operating System of the Phone

A common but often overlooked fix for the issue where one side of the earbuds is not working is to update the operating system of your phone.

This simple step can resolve many underlying software glitches that might be affecting the Bluetooth connectivity and performance of your earbuds that was culprit for one side not working on Bluetooth earbuds.

Reset the Bluetooth Settings

  • A reset of your Bluetooth settings and remove all prior connections is a similar and often effective first step to fix the issue of wireless earbuds that work on one side only.

This process clears any conflicting configurations that might be causing the problem of one side not working on Bluetooth earbuds.

Buy a New Pair or Set of Earbuds

Sometimes, the best possible solutions to fix an earbud where only one side works, if met with no success, is to replace the pair of earbuds with new ones.

If an earbud has malfunctioned beyond repair, the most straightforward action is to purchase an exact copy or explore a different brand.

It’s important to recognize that old earbuds are bound to malfunction in the future, especially if their quality has deteriorated over time.

Check Water Damage

When dealing with earbuds where only one side works, it’s crucial to consider the possibility of water damage.

  • Earbuds are often prone to such damage, and even those with an IP waterproof rating might have insufficient protection.

If your device does get wet, it’s important to dry it as quickly as possible using a towel or napkin, especially after a workout where sweat could be an issue.

Always allow your earbuds to dry completely before charging or placing them back in their charging case.

Check Audio File &Internet Connection

Another point to consider when facing issues with one of your earbuds malfunctioning is to check the audio file you’re listening to or the internet connection.

Sometimes, these external factors can be the underlying reasons for the apparent malfunction of the earbuds.

Clean Earbuds

Earbuds, despite having a protective mesh material, can fall victim to dust and other elements, leading to situations where one side does not work.

  • Accumulation of gunk and earwax might block an earbud, causing temporary malfunctions.
  • The key to preventing this is to clean your earbuds regularly. A cotton swab or a piece of soft fabric is ideal for this task, ensuring your earbuds stay in top condition.

Draw Closer to Device

An effective strategy when one side of your Bluetooth earbuds is not functioning properly is to draw closer to your device.

  • Often, being out of range – typically more than 30 meters or 33 meters – can cause connectivity issues.

Try to Forget All of the Devices

A practical approach when faced with the problem where one side of the earbuds only works is to forget all the devices in the Bluetooth list.

This can be particularly effective if your device has a bulk cache of various Bluetooth devices. The solution here is to remove these connections and then reconnect your earbuds.

When you encounter pairing issues with your earbuds, where one side not working on Bluetooth earbuds or fails to pair with your audio device, there are some quickest fixes you can try.

First, ensure that your earbuds are unpaired from any other devices and that they are paired with each other.

If the automatic pairing feature is causing problems, consider unpairing them and then re-pairing manually.

Keep in mind that pairing instructions may vary depending on the earbud model, so refer to the specific inserted in the charging case briefly for guidance.
