I'm not sure I understand the question.
But it's actually a voice microphone.
And if you ever want to use it on a device other than a JBL with a 6.35mm jack connector, that's also possible.

Yes you can also use the mic to speak, we also used it to comment on games at a wedding or to inform the guests. It is recommended that if you use it with a JBL party speaker that you switch the EQ to voice (but this is a setting of the speaker not the mic).
