One wireless earphone does not work

There are times when only one of the speakers does not work. This does not mean that the device is broken. It is necessary to determine the cause of this phenomenon.

Why doesn't one wireless earphone work?

There are several reasons why one of the headphones may not work. Among them:

1. The speaker is clogged with sulfur.
2. The element required for power supply is not positioned correctly.
3. The headset is not positioned correctly.
4. Errors during the connection process.
5. The settings on the audio source are incorrect.
6. The Bluetooth capsule is not positioned correctly.

All breakdowns are identified and corrected on an individual basis.

How to determine the cause

The reasons can be determined as follows:

1. Check the device, if it is clogged with sulfur, you will see it. They should be cleaned and proper hygiene observed in the future. But you can purchase special headphones that are protected from sulfur.
2. The battery needs to be checked. Bluetooth headphones work wirelessly, but require a battery. It is necessary to make sure that the battery is positioned correctly, namely the polarity.
3. If the headset is positioned incorrectly, try reading the instructions for use.Some headphones will only work if they are worn around the neck or on the arm (it all depends on the individual antenna parameters).
4. When using the headset for the first time, you need to look for the device in the list of active ones on your phone. But many headsets have similar names, so it’s easy to confuse them with those that were connected earlier. You should clear your phone memory or use the search.
5. If the settings are incorrect, they should be corrected. Most often, the default device is the phone speaker, not the headphones. You need to change this setting in the settings. But if the sound does not reach the phone's speakers, then there is another reason.

Attention! Make sure to position the device correctly in your ears. The speakers have a very narrow directionality. There may be nothing wrong with the device itself, but it is positioned at the wrong angle and the walls of the ear canal are blocking the path of sounds.

How to fix the problem

Depending on the breakdown, you can repair your Bluetooth device either at home or by contacting a service center. Minor damage and defects can be corrected with your own hands.

Sulfur contamination

You need to do the following:

1. We take a needle.
2. We take out the dirty filter.
3. We check it for the presence of sulfur.
4. We carefully clean the speaker, trying not to damage the latter.
5. We install a new filter.
6. We connect the headphones and check the operation.

Battery is placed incorrectly

The problem here concerns polarity. Check the placement of + and -. For devices 11 mm + outward, and - inward. For 9 and 6 mm it’s the other way around. If after inserting the battery you hear a slight noise from the speaker, then you did everything correctly.

The headset is not placed correctly

Some headphones only work on the neck, and some only on the arm.It all depends on the individual characteristics of the antenna. Read the instructions to understand how to use the device.

The headset was not connected correctly

If your phone has a lot of similar titles, try clearing the memory. Then there will be only one thing left that we need. Another good idea is to rename the name of the device you are using.

Incorrect settings

By default, many phones send audio signals through the speaker rather than through headphones. You need to do the following:

1. Go to your phone settings.
2. Find the name Sound or Sound Source (may be slightly different depending on the model).
3. Select headphones as source.

The earpiece is not placed correctly in the ear

Everything is simple here. Place the speaker where you can hear it clearly.

Other problems

But there are also breakdowns that require you to contact a service center:

1. Moisture has entered the device. This leads to damage to the contacts.
2. The device fell from a great height.
3. You accidentally pressed down the speaker.
4. The contacts have oxidized (the battery was inside for a long time; it must be removed if you do not use the headphones).
5. If you bend the headset loop, there is a risk of breaking the induction wire winding.

You can also solve these problems yourself if you know how to use a soldering iron and know the internal structure of the headphones.
