The NEEWER CM22 is a mini wireless lavalier microphone system with 2 transmitters (TX) and 1 receiver (RX). It offers 7 hours of operation on a full charge, ideal for extended outdoor audio recording, podcasting, and live streaming. The included protective charging case allows for simultaneous recording and charging, with a charging time of just 2 hours. The RX features a 3.5mm audio jack for real-time audio monitoring. The receiver also functions as a recording pen with 4GB of memory, storing up to 9 hours of uncompressed 48KHz WAV audio files. Choose from 3 audio export modes.

It also supports a one-decibel (dB) gain adjustment. The LCD screen displays export modes, volume, battery level, connection status, noise reduction, and other information. The advanced noise reduction chip built into the TX transmitters enables clear and crisp voice recording with a single click of the same button. Two LED indicators display different recording statuses. Two noise-canceling windscreens and a magnet in each pack are included for magnetically attaching the lavalier microphones to collars or other surfaces.

In open areas, the CM22 provides seamless wireless transmission up to 150 meters for stable audio recording and increased resistance to interference. However, the transmission range may vary depending on the location. It is widely compatible with iPhone 15 Pro Max Plus, iPhone 14/13/12/11, Samsung Galaxy S23 Ultra, and many more, thanks to the included Type-C OTG adapters. A white USB A to Type-C data cable is included for data transfer from PC and MAC, while the black cable is for charging only, and a camera audio cable is provided for connecting a digital SLR camera.
