Have used together with Panasonic SD99 the microphone. The quality is surprisingly good for the price, I had the sound signal at -18dB runterschrauben to get a clean sound. Tried the holder on the T-shirt to be fixed, but that's not possible then. Sorry slips over and only a little fumbling, I was able, that it does not fall off. The cable is long enough, it should be about 2 meters, but it is not measured. I am satisfied with the product, only the holder could be improved. Who itself wants to get an idea of the sound quality, it should enter times on Youtube, there are some who have already tried it. It is definitely the price / performance ratio absolutely recommended.
