I use this microphone both at different live events (in large halls or outdoors), as well as at the music classes I teach at a specialized school. The wireless system has always worked flawlessly, without signal loss and with very good frequency clarity, in various registers (both male and female voices). I also recommended to other colleagues this microphone and they are just as happy. The frequency of 1.8 Gh is clearly higher than the lower of 1 Gh, firstly through stability. I did not notice the latency (delay of signal reception). I am a professional musician and I assume everything I have written in this feedback. At this price I did not find any better microphone! I recommend it to all musicians, both amateurs and professionals.
