They only weigh 20 gram so it's very easy and inconspicuous to wear or put in your pocket for your brilliance there is a built-in mic on top, a 3.5mm jack to connect a lav mic,Now the dual receivers look very different there are two large physical dials for controlling the level of each audio channel you can push in to mute each transmitter and then there is a screen in the center that shows the battery life level And the status of each unit has a dedicated power button on this one so you can keep it on the camera without draining the battery plus . there's the headphone jack of course the headphone jack in the camera should be used whenever possible but Putting a headphone jack on the receiver is very useful for troubleshooting and peace of mind your camera and the magnet on the bottom is now the size of a country mountain and attaching it to your camera is very simple, you just put it on can stay there.
