There is a question that I turn in my head for years: why do you buy what is still more expensive? ...
You think it's for quality?
With what follows, I will show you that the price bears no relation to quality.
In a large hall with a cathedral of sound (echo!). I stood in back of the room, about 20m from the receiver and the sound went smoothly, no cuts, no noise.
While talking to himself (yeah like crazy, but hey, be good to test), I'm back from the depths of the hall towards the sound, I even passed the speakers while speaking: no feedback! !
And no problem during the evening + night. Of course, I thought to put the microphones off when I do not use it to preserve battery life.
In short, look no further, for example among brands that explode their prices to make people believe they have a better quality stuff. If you are sincere and realistic, and for the same service rendered, admit that 80 euros is still more honest than 5 times more expensive! No?
And on sound quality, even if bandwidth is not the kind 20Hz to 20KHz, remember that a leader is not a baritone or a soprano! By purchasing a microphone with a bandwidth larger (therefore more expensive) is like buying a Ferrari to do so only in the city ...
Conclusion: I recommend this wireless microphone system to all leaders who need to speak at the microphone while moving indoors. You will not regret it.
