Microphone acoustic audio input port — The microphone receives the audio
signals via this port. Do not block this port while the microphone is in use.

Audio input port (Audio In) — Connect an MP3 player or other audio device to this
3.5 mm TRS jack for auxiliary audio line input. When a device is plugged into this port,
its audio is mixed with the signal from the internal microphone.
NOTE: Because the audio input is mixed with the microphone input, pressing the
Volume button on the microphone affects the volume of the audio input device.
However, it is recommended that you use the volume control of the input device
instead of the microphone Volume button to adjust the levels of this audio input.
