Clip the small mic to your shirt, connect it to your phone, camera or computer, and check the sound before you record. A lavalier mic sits close to your mouth, so it picks up your voice while the camera stays back. The steps below cover clipping, connecting, noise control and a sound check.
Clip the mic to your clothing
Clip the mic to your shirt or jacket near the center of your chest, with the capsule pointing up toward your mouth. Leave a little slack in the cable so head turns do not tug the mic. The mics in this guide are omnidirectional, so they pick up sound from all sides, and the clip keeps the mic in place while you move.
Connect the receiver or the cable
For a wireless set, plug the receiver into your phone or computer and clip the transmitter to your clothing. The NEEWER KM19 receiver uses USB-C, and the Ecomxia WM300 plugs into iPhone, iPad or Android devices. For a wired mic, plug the connector into the matching jack: the Rode SmartLav+ uses a TRRS jack, and the Rode Lavalier GO uses a 3.5mm TRS connector.
Set noise control and output mode
Press the transmitter once on the NEEWER KM19 to change between its 3 noise cancellation levels, and press twice to mute or unmute. The Ecomxia WM300 offers 3 noise reduction modes, and its M button powers the mic off to save battery. Press the NEEWER receiver once to switch between stereo and mono output: stereo shows a purple indicator and mono a blue one.
Do a sound check before recording
Record a short check and play it back before the real take. The NEEWER KM19 lets you replay audio without unplugging the receiver, so you can hear the level and the room sound at once. Listen for clothing rustle where the cable touches fabric, and move the mic or the cable until the rustle stops.
Fit the windscreen and charge the set
Fit the windscreen over the mic when you record outside or near moving air. The NEEWER KM19 includes furry windscreens, and the Rode Lavalier GO includes a foam pop shield. The NEEWER transmitter records up to 6 hours and the case extends total runtime to 30 hours, while the Ecomxia WM300 works up to 8 hours on a single charge and its case shows the remaining power in 4 indicator lights.
