It will perfectly fit. Though you still may need to change the speaker when using it with an external mic. For example, to switch the "Line In" to "Microphone", or you need to switch from FM Mode to another proper mode for using the mic.

It requires a signal that has a higher level of power than a mic signal does. Mismatch will result in low sound. So we don't recommend using the mic with the small speakers.

Make sure there is a 3.5mm microphone input jack on your camera. Because some cameras only have an "audio out" jack, not an "audio in" jack. And whatever kind of camera USB jack is not compatible, which does not allow audio input.

The (1/4'' to 3.5mm TRS) included adapter is for cameras only; it is NOT compatible with smartphones.

You'll need to buy a different adapter cable from our site if you want to use the mic with a smartphone that still has a 1/8" jack.

Note:

Make sure the transmitter has paired with the receiver before you plug the system into any device. (Receiver light remains RED, that means connected.)
