-connect your phone to loud speaker or headphones (AUX, Bluetooth).
-use your smart phone as a live microphone.
-like all sound systems be carefull of echo looping. so dont turn on live mode without connecting to a remote speaker. and get a little far from the loud speaker.
– in the eavesdrop mode, connect to a head phone turn on live and place your phone in the nearest position. it will catch any tiny conversation (SUPER EAR)
