This stereo FM wireless microphone also makes a great quality audio link. We tested it to beyond 50 meters and it was rock solid. It s certainly not the first wireless microphone we ve ever published but this one is a little different. It s stereo, providing surprisingly good quality sound. Second, it has a really good range. We tested it at well over 50m and it was still performing very well noise-free, in fact but at the time we couldn t get our receiver any further away. So it s likely to have even better range than that..
