Simple product and can expensive to connect the dedicated video output cable (his camera to his TV: 2 + 1 video audio) to headphones to monitor the sound of a live video recording of his camera. Ideal for my Canon EOS 650 dedicated to video STM with its objectives. Of course, the sound is revealed more accurate using an external microphone jack on flash see on a monopod extension held by another person. The helmet then allows closer or away soundman compared to the intensity of sound collected in the helmet. The most expensive model of apn have VU meter and headphone jack but it's the same price !!!!! Kenable seller amazon partner and serious.
