I'm looking for a decent set of wireless handheld microphones for singing. I will need to buy 3/4, and also use those at the same time. Since I have 0 experience with any proper wireless singing microphones, I need help. There's no set budget, BUT, top of the line will be a bit difficult. Is it possible to get something in the 150-200euro range (per set), which work decent, and sound ok?
