How to use

Clip the lavalier microphone onto clothing near the speaker’s mouth and place the receiver into the smartphone’s USB port. For wireless operation, power on both transmitter and receiver; they will pair automatically when in range. For wired use, connect as indicated by the product’s cable options. Charge the transmitters and the storage/charging box using the supplied cable before use. If a phone does not detect the receiver, enable OTG in the phone settings (commonly required on some OPPO and VIVO models) and reconnect.

Usage recommendations

Ensure the microphone capsule is positioned correctly on clothing to avoid rustling noises and keep the transmitter and receiver within the stated wireless range. Enable OTG on phones that require it and test the connection before recording to confirm compatibility.
