A lavalier microphone is a clip-on microphone that fastens to clothing near the speaker's mouth and records speech while leaving the hands free. It connects to a phone, camera, or transmitter by cable or by a wireless link. It sits close to the mouth, so it picks up the voice more directly than a phone or camera microphone.
What a lavalier microphone is
A lavalier microphone is a small microphone with a clip that fastens to a shirt, jacket, or lapel so it sits near the mouth. The speaker wears it instead of holding a microphone, which leaves the hands free and keeps the distance between the mouth and the microphone steady while the speaker moves. It is used for interviews, video recording, vlogging, online meetings, and live recording, where the speaker needs to move and talk at the same time.
Wired and wireless versions
A wired lavalier connects to a phone, camera, or audio interface through a cable, and the cable carries the signal to the recording device. A wireless lavalier sends the signal from a small transmitter on the speaker to a receiver plugged into the recording device, so no cable runs between the speaker and the camera or phone. Wireless sets run on batteries, so check the stated battery life and the range before a long session.
How to clip it on and place it
Clip the microphone to the front of a shirt or jacket near the center of the chest, with the capsule facing up toward the mouth. Keep the cable slack so a tug on the cable does not pull the microphone off, and use the mounting clip that comes with the microphone. A foam shield over the capsule cuts wind noise and the hard burst of air from consonants such as b, t, and p.
What to check before you record
Plug the microphone into the recording device and speak a few sentences while watching the input level. Set any noise cancellation level or mute control before you start, and on a wireless set confirm the transmitter and receiver are linked. Record a short clip and play it back to confirm the voice is clear and the level is not too low or too high.

Frequently asked questions
Does a lavalier microphone need a battery?
It depends on the model. Some wired lavaliers draw power from the phone or camera, others use a small battery, and wireless lavaliers run on a battery in the transmitter. Check the power source in the product specs before you choose one.
Can I use a lavalier microphone with a phone?
Yes, if the connector matches the phone. Some lavaliers plug straight into a phone jack, others use a USB-C or Lightning receiver, and wireless sets pair a small receiver with the phone. Check the connector and the listed compatible devices first.
Why does my lavalier microphone sound quiet?
Check the placement first: the microphone should sit near the center of the chest facing the mouth. Then check the input level on the recording device, the mute control, and whether the transmitter and receiver are linked on a wireless set.
