Check the user manual

In fact, on the first use, some headphones automatically switch to pairing mono tracks. So many people think that Bluetooth headphones can be readily available without any installation. However, this statement is not entirely correct.

CEO of Jlab Audio – a brand specializing in making low-cost wireless speakers – Win Cramer had a headache when Bluetooth headphones did not connect for the second time. So when you try to connect, and the transmitter doesn’t show up with Bluetooth headphones, we think it’s time to recheck the user manual.

When you buy Bluetooth headphones, you will receive a paper or a quite detailed user manual. Review the manufacturer’s instructions on how to put the headset in pairing mode.

Usually, you just need to hold down the power button for a few seconds. However, some Bluetooth wireless headphones have a different method. For example, touch-controlled headphones require a separate connection.

Disconnect other devices

Normally, the working principle of Bluetooth headphones is to only connect to a single transmitter. In other words, your Bluetooth headphones cannot pair with both devices at the same time.

Once you connect to the iPad, Bluetooth headphones will not connect to any other devices. It is a common principle in most headphones.

But now, some Bluetooth headphones have improved and allowed connecting to multiple playback devices simultaneously.

So when your Bluetooth headphones don’t work, try disconnecting the headphones from another device. Chances are your one ear headphone is among the more popular.

Disconnecting will force the Bluetooth headphones to return to their original pairing mode. Now you need to select the transmitter and connect.

Disconnect the device from another headset

Similarly, your transmitter does not allow simultaneous connection of 2 Bluetooth headphones. So make sure they are not connected to any other headphones.

Because when turned on, your phone is straightforward to reconnect to Bluetooth headphones that have paired before. As long as the two devices are within range, they will automatically connect. To avoid such a situation, you can delete the old Bluetooth connection from the phone memory.

For iOS, go to Bluetooth audio settings and click on the ‘i’ icon next to the Bluetooth headphones you want to remove. Then you click ‘forget device’ to remove them from the device.

As for Android devices, you do the same. These two operating systems only differ in symbols, and the operation and location are the same.

Close the gap

If you are listening to music, but suddenly one of the headphones stops working, the sound is choppy. We think it is because you are too far away from the transmitter or the connection line encounters many obstacles.

Although most Bluetooth headphones can connect within a radius of 33 feet to 100 feet, this distance is in open space conditions. That is, there are not many obstacles, or there are too many wifi signals that interfere with the signal.

The best solution to this problem is to bridge the gap between the transmitter and the Bluetooth headphones. Also, stay away from other signal generators.

Bluetooth headphones require a battery to work. We recommend that you fully charge the battery for the headset to work properly. Because the headset battery is low, you will have some pairing problems, and the Bluetooth headphones will not work.

Some headphones still work while the battery count is close to 0%. But it will drain very quickly and affect the sound quality. Charge the batteries even if they have a little bit left.

Like most other technological devices, Bluetooth headphones have also undergone a revision process with many improvements. To this day, many models of Bluetooth headphones are equipped with many modern features to meet the needs of everyone.

Up to now, Bluetooth 5.0 is the latest technology applied in some headsets. This technology allows Bluetooth headphones to connect to most devices.

However, for some transmitters such as phones and computers too old Bluetooth headphones cannot connect.

So, to troubleshoot your headset, check if your Bluetooth version supports it. Then, you need to make sure the two devices including Bluetooth headphones and phone or computer are compatible with each other.

Check if the headset is clean

A clean and dry pair of earbuds Bluetooth headphones should provide good sound. If the Bluetooth headphones are dusty, waxy, or lint, the sound cannot be played, leading to a situation where one side works, and the other does not.

So, the first thing you need to do is check that your Bluetooth headphones are clean. Usually, people have the habit of putting one ear headphones in their pants pockets, shirt pockets, or bags. This action causes Bluetooth headphones to accumulate dust and lint.

So if you find dirt, clean it with a dry cloth. If the device gets wet, dry it using a microfiber cloth to absorb the water.

Check the audio format

Current Bluetooth headphones sometimes can’t play some old audio formats. It is because your headset only works on one side.

Because the problem is not always with the one ear headphones, you need to check to determine the correct cause of the problem. Old types of audio formats sometimes cause interference, even causing both sides of the headset not to work.


The models all have different specifications. That’s why they have different ways of working. What you need to do now is to learn about the parameters on your device carefully.

Some Bluetooth headphones allow users to reset all settings. To do this, refer to the instructions for use from the manufacturer.

In general, most Bluetooth headphones on the market today have the following implementations. First, the user needs to make sure the headset is turned off, then restart it. If the headset has a power button, press and hold it for a few seconds.

Some special bluetooth earbuds that support touch control will have their way of starting. If that still doesn’t work, try doing the same for the volume up and down buttons.

Check the connection audio jack balance

Many users do not know that wireless earbuds like iPhone, Mac, and Windows PC all provide the option to adjust the sound to the right or left side of the headset. Carriers have provided this feature to assist hard-of-hearing users.

So when your Bluetooth headphones are only working on one side despite trying the above solutions, the cause may be by mistake. The settings have been adjusted. The solution now is to change the stereo sound by going to the settings on the transmitter.

How to adjust stereo sound on iOS

  • First, you need to go to the ‘settings’ section of your device’s menu and then click on ‘accessibility’. For older iOS devices, you may need to go to the ‘general’ section to get ready for the next steps.
  • Scroll the screen until you find the ‘auditory’ category. In this section, you go to ‘audio/visual’ to adjust. To ensure that the sound plays evenly on both sides of the headset, you need to ensure the slider is at the point between L and R.
  • Note, for older iOS, this slider is in the ‘hearing’ section.
  • Also, pay attention to the Mon Audio button at the top. Turn off the mono sound to perform the L R tuning.

How to adjust stereo sound on Mac

  • For Mac, you do the same with wireless earbuds when only one. But the path to the L R bar is a bit different.
  • You need to open ‘system preferences’; in this, you click on the ‘sound’ item and then ‘output’. A menu panel will now appear on the screen. Select the name of the headset and make sure the slider is in the center L R.
  • And when you need to work on a single audio jack checkbox, you go into ‘system preferences’ and go to accessibility.
