Very "fair" and decent wireless. I have used it for singing (Hard Rock/ Stoner) in small and medium-sized venues (up to 250 people) and it has not let me down. Clean sound without dullness or distortions. I also combine it with vocal pedals (harmony + Megaphone) and it works flawlessly without any loss of gain or whistling, as long as you spend a little time finding the ideal settings on the pedalboard. I recommend it to anyone who wants an affordable wireless for decent live performances. I haven't tested it yet in open spaces (festivals and concerts), but based on my experience so far, I don't think it will have any problem there either!!!!!!
