Why Is Only One Side of My Bluetooth Earbuds Working?

Before beginning with how to fix bluetooth earbuds when only one side works, let’s look at some of the reasons behind this issue. It is important to note that we only provide some of the causes; if your wireless headphones are not among them, then it’s time to talk to an expert.

Connection Issues

This is one of the most common reasons for bluetooth earbuds working on one side. This problem can occur if your device does not have enough power or if you have moved too far from your device. In addition, most Bluetooth devices are designed to connect with a single device at a time. So, make sure you turn off Bluetooth on any other devices you’ve previously connected and try again.


If you don’t handle your wireless headphones with care, you’ll eventually get to a point where they will break or no longer work properly.

The good thing is that you can fix this by simply replacing the broken part. In some cases, it’s not very easy to tell if your earbuds are broken. This is especially true when you’re using Bluetooth in-ear headphones and you can’t see anything while they are on your ears.

In such cases, we recommend that you try using another pair of headphones and see if the issue persists. If the problem no longer exists when using another pair, then you know the culprit is your Bluetooth headphones.

Low Battery

Your device might be running on low power, which may result in an imbalance in sound or even no sound at all. However, make sure that you have charged your device fully before connecting it to your smartphone or laptop. If this doesn’t work, then you can use the above-mentioned methods to fix the problem.

If they are not charging, then check if there is a loose connection between the charger and the headphones. If you are using a USB cable, try using another one because it may be damaged.

Audio File Issues

The audio files you play on your device can be damaged or encoded incorrectly. You can check this by playing these files on other devices. For example, if you have a laptop, you can use it to play these files.

If only one side is working and the other one is not, then the issue is with your computer. In this case, it would be better to contact the manufacturer because you may need a repair or exchange.

How to Fix Bluetooth Earbuds When Only One Side Works

There are a few solutions to this problem, but they all depend on the type of headphones or earphones you’re using. Furthermore, each Bluetooth headset or earpiece has a unique repair method.

Try an Alternative Pair of Headphones

The first step is to determine if your headphones are causing the issue. One option is to get a new pair of headphones that is in good working order and connect them to your device. 

If you don’t have a second pair to use, try borrowing a pair from a friend. If all is well, you can be sure that the issue is the headphones. In the event that both headphones are working on one side, change the audio settings on your device.

A Reset Could Be Needed

If you’ve determined that your headphones are failing in one direction, one option is to offer them an easy reset. It’s a breeze to accomplish, just hit the power button of your gadget and continue pressing until the headphones turn either red or blue. Try connecting the headphones to your device to see if it is working.

Look For Broken Wires

When your headset is charged but isn’t working on one side , then you’ll need to look for damaged internal wires. To find them and do it is simple. You need to open the Bluetooth device and then remove the case. 

Utilizing a soldering iron, locate the damaged wires and then connect them. Then, you can place it back inside the case. Turn the Bluetooth function on again and test the function.

Check If It’s On Mono Setting

If the audio settings are set to mono, the sound will be heard via one of the headphones’ speakers, which makes you believe that they’re damaged. This is a problem since you might accidentally discard an excellent pair of Bluetooth headphones. So make sure you check this out!

Get the Most Value From Your Warranty

A majority of earbuds, especially those with higher prices, typically come with at the very least a 6-12 month warranty. If your earbuds fail within the warranty period, it’s advisable to take advantage of the offer and have them repaired professionally. 

Making an attempt to repair your earbuds on your own could void the warranty in the event that the fix doesn’t work and they are damaged, and you’re stuck with a damaged pair of headphones.

If you’re an expert in technology, you can repair them yourself, and you can preserve the warranty longer. However, if you’re not sure of the basics, it’s not worth the risk.

Cleaning the Earbuds and Case

The first thing you should do is clean your earbuds and the charging case. Doing this can help fix Bluetooth earbuds when only one side is working and improve their longevity. All you need to do is clean these items using a lint-free cloth and some dry cotton swabs or Q-tips.

If you have some isopropyl alcohol handy, you can use it on the earbuds, but be careful not to let any moisture accumulate in the charging ports or other crevices where it could get into sensitive electronics.
