In my testing this mic sounds just as good as the Sennheiser ME2 lav when used in a Sennheiser G3 wireless system, when on a 5D3 or a handheld recorder is recorded. It's actually slightly more sensitive than the ME2, which is good as the preamps don't have to work as hard. It's slightly smaller than ME2, so it's easier to hide. The cable is thinner and thinner than the ME2, so I wasn't keen on it, but as long as the talent isn't rough on it and you take good care of it, it should last. Unfortunately I had to return this lavalier as it requires "plug-in" power, a small voltage of more than 2 but less than 10 volts, and will not work with my optional wireless system transmitter which does not draw power from the plug-in delivers.
