If you are unsure, check the microphone type on your headset.  Any microphone that is labeled dynamic will be low impedance and require this option.

High impedance (electret or other non-dynamic microphones) push to talks are compatible with the electrical systems of certain headsets specific to Law Enforcement like TCI headsets with high impedance, or black MSA Sordins
