Note:
1. EDC microphone unit belongs to cardioid type. It perfectly receives the voice of
the in-front speaker. The sound reception from other directions would be
reduced.
2. The in-front speaker and the microphone unit should keep with the proper
distance to make the microphone completely receive the human voice. Or, it
would cause sound offset due to the time difference of sound receiving.
