The system consists of a transmitter and receiver and each transmitter of the M2 weighs less than 30 grams and has a built-in clip and an omni-directional microphone, so it can be easily attached to a lapel or shirt for quick and easy wireless audio recordings. 
With a frequency of 2.4 GHz bandwidth system, the M2 has a maximum range of 100 meters. 
The microphone itself has a 3.5mm TRS (stereo mini-jack) output, which can be connected to a camera, audio recorder or other equipment with a 3.5mm audio input.
The frequency response of the Movelink II M2 is 50 Hz to 20 kHz, which means that the microphone can record audio in a wide frequency range. The sensitivity of the microphone is 90 dBA, which means it is able to pick up relatively loud sounds without distortion.
The transmitters and receiver are equipped with internal rechargeable lithium-ion batteries that last all day. They can be charged via the USB Type-C ports.
