The IRNEHARUITI M107 system consists of two main units:

Both units feature indicator lights for connection status, battery level, and charging.

5.4 Intelligent Noise Reduction
The M107 incorporates an intelligent noise reduction function with a built-in DSP sound processing chip. This technology actively filters out ambient interference, providing professional, clean, and clear audio quality (20~20kHz stereo CD quality).
