For some reason I don't want to use my more expensive real lavaliere so I made a cheaper version lavaliere microphone from a telephone headset. See video at minute 2:35. It work fine on my GH3 but it doesn't work as intended on my zoom H1. Both devices need a 3,5 mm min jack plug. Anybody a clue why it doesn't work?
