1.There are two types of standards for headphones: the OMTP standard is often referred to as the national standard, and the CTIA is known as the international standard.

The difference between the two is that the last two sections of the plug, GND and MIC are in reverse order. CTIA headphones are compatible with OMTP devices, and CTIA headphones plugged into OMTP devices will cause the sound to be small and distorted, and the sound will resume when the MIC key is pressed, so that the device can be identified as OMTP standard.

It is a headphone interface standard with MIC, commonly known as the national standard, which is used by the state. The pins are connected (from the beginning): Left Channel-Right Channel-Microphone-Ground.

3.There is also a headphone jack with MIC is an international standard, called CTIA, and the pin connection method is: left channel-right channel-ground-microphone.

I've had this problem before and it's clear now:

There are now two types of 4-band headphones with microphones.

Xiaomi uses domestic standards, while many use international standards.

The main difference is that the two wires (GND) and MIC (microphone) are reversed, so you will encounter your phenomenon.

Solution: Find a headset that is compatible with your Xiaomi phone. Or buy a converter.

Here's my answer, I hope to give you an idea:

Hello theory supports the American standard, but the actual situation depends on the hardware compatibility, not guaranteed that all headphones are compatible, it is recommended that you purchase supporting products from the official website. Please see for details.

Have you tried other headphones? If the situation is the same, go to Xiaomi's official website for consultation, good luck.

The reason why Xiaomi mobile phones don't work with other headphones:

1. This is a mobile phone that is not compatible with headphones, if you want to use it, you can buy a headphone adapter.

2. The standards of mobile phones and earphones are different, which will cause the earphones to be unusable.

3. If the ground cable of the earphone falls off, it will also lead to the situation that there is only an accompaniment sound and no vocals.

In addition, today's smartphones are basically *** type into the hole, but there are advantages and disadvantages:

The disadvantage is that it can't give us a good experience in terms of sound quality, and the advantage is that the best headphones can basically be used, and you can also enjoy hi music on the sound.

1.The mobile phone is not compatible with the headphones, and the size is different, so you can buy the headphone adapter.

2.The standard of the mobile phone and the earphone are different, and the remote control and microphone may not be used.

3.Falling off the ground cable of the earphones will lead to a situation where there is only an accompaniment sound and no voice.

In this case, it is possible that your headphones are used incorrectly.

The headphone plug is available in OMTP and CTIA. The biggest difference between the CTIA protocol and the OMTP protocol earphones is that the definition of the two metal contacts containing the microphone and the ground wire on the plug is opposite, which supports the devices that cause different protocol earphones to be incompatible with each other.

As for the earpiece ringing after insertion, it may be that the metal contacts of the earphone jack are not deformed. The headset was replugged and unplugged several times for testing. That contact is responsible for turning off the phone speaker. Just plug in a few more rebounds.

If the headphones are not broken, consider the problem with the phone jack or hardware.

If the phone's jack is broken. It is recommended to go to the after-sales service.

If the jack is not broken, see if it is a system problem, you can restore the factory settings or flash the machine.

There is also a problem with the back line, or after-sales maintenance.

Maybe the phone's socket is broken.
