How can I distinguish OMTP and CTIA ?

The middle three isolation rings of the American standard CTIA are generally white, while the national standard OMTP is generally black. Most earphones can be distinguished by this method.

2.5mm to 3.5mm and 3.5 to 2.5mm TRRS adapter is designed to convert from CTIA standard to OMTP standard. This means:

CTIA Standard Jack Earphone to OMTP: It can convert headphones with a CTIA standard jack to work with a device using the OMTP standard. OMTP Standard Jack Earphone to CTIA: Unfortunately, it does not convert headphones with an OMTP standard jack to work with a device using the CTIA standard.

Why my Microphone Might Not Be?

Understanding TRRS Standards: There are two primary wiring standards for TRRS connectors used in headphones with microphones, CTIA and OMTP.

If the adapter or the device uses a different wiring standard than the headphones, the microphone won’t work properly.If your headphones use the OMTP standard and your device uses the CTIA standard, this adapter will not work for your setup. The wiring mismatch means the microphone signal and ground will not align correctly, causing the microphone not to function.
