Problem phenomenon:
In a quiet environment, the earpiece may have a current sound when making a call and listening to social apps' voice messages.
Solutions:
In a quiet environment, when the screen is interfered with by the signal, there will be a slight noise. If the ear is close to the receiver, a weak current sound may be heard. It is a normal phenomenon. This phenomenon is not a hardware problem of the phone.
Other possible reasons and solutions:
Loose or damaged wires. If the wires connecting your headphones to your device are loose or damaged, it can cause an electric current to leak into the earpiece. This can cause a buzzing or humming sound.
Improper electrical shielding. The headphones themselves may not be properly shielded from electrical interference. This can also cause an electric current sound to be heard in the earpiece.
Electronic interference. If there are other electronic devices nearby, such as a computer or TV, they can emit electrical noise that can be picked up by your headphones. This can also cause an electric current sound to be heard in the earpiece.
To troubleshoot the problem, you can try the following:
Check the wires connecting your headphones to your device. Make sure that they are properly connected and that there is no damage to the wires.
Try using different headphones. If you have other headphones, try using them to see if you still hear the electric current sound.
Move away from any other electronic devices. If there are other electronic devices nearby, try moving away from them to see if the sound goes away.
Update your device's software. Sometimes, software updates can fix problems with electrical interference.
If you have tried all of the above and you are still hearing an electric current sound in your earpiece, you may need to take your headphones to a technician for further diagnosis.
Here are some additional things you can do to prevent electric current sounds from happening in your earpiece:
Keep your headphones away from water. Water can conduct electricity, so it is important to keep your headphones away from water.
Do not use your headphones in high-moisture environments. High-moisture environments, such as bathrooms, can also conduct electricity.
Use a surge protector. A surge protector can help to protect your headphones from electrical surges.
