Lenovo A765E is the original headset is CTIA headset, so the headset is compatible with OMTP but you have to press the MIC button.

I'm sorry to confuse you, but there are currently two international standards for mobile phone headphone interfaces, one is the OMTP standard, also known as the national standard, and the other is the CTIA standard, called the American standard. Lenovo A765E headphones use the OMTP standard, and Lenovo A830 headphones use the CTIA standard, so their headphones are not universal, please understand.

If you still have relevant doubts, it is recommended that you contact Lenovo authorized repair sites in time and hand them over to engineers for testing and maintenance, which you can visit.

Find the nearest site. The business hours of the maintenance site are usually from 9:00 to 18:00 from Monday to Sunday, except for holidays, and the stations will be slightly adjusted according to their own operations.

1.The headphone jack standard of Lenovo A820 mobile phone is the national standard, which can be adapted to all national standard headphones.

2.There are two standards for headphone plugs: 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 headsets are compatible with OMTP devices. Plugging CTIA headphones into an OMTP device will cause the sound to be low and distorted, and the sound will resume when the MIC key is pressed.

This allows the device to be identified as OMTP standard and the headset as CTIA 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.

4.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.

Yes, the SH100 headphones are available.
