Didnt have the chance to try it on the field yet but it looks pretty solid. Voice can sound a bit low at first but it also depends on the positionin on throat. i guess it takes some practice to find the best point. so far we have tried two of them together and turning on the volume was helping. Havent tried with people using regular mics yet. if their sound comes too high that might be an issue.
as the pictures totally recomended
