Konftel Expansion Microphone Cable for 55 and 300 Series Conference Phones (20′)

This 20′ Konftel Expansion Microphone Cable is used when a longer cable is required for an expansion microphone connected to a 55 or 300 Series conference phone. It allows you to position the mic close to meeting participants that are further away from the conference phone and improve the audio quality of your phone calls and video conferences.
