An excellent 4 mic set, fantastic value for money!

By: AllanM on 25 June 2019
Bought this set to use in a church worship band for backing singers. I was taking a bit of a punt with them regarding audio quality and wireless stability. Well, they exceeded my expectations! All users were very happy, not a single dropout after several hours use, no feedback issues and needed hardly any eq'ing other than normal tweaks. I am very happy to recommend this set to anyone, they are fantastic for the price!!!
