Purchased initially for Brass section in Live sound application and found them far better than a Mic an a stand for managing levels, isolation and quality, as you aren't in the lap of the gods as to where the performers point their instrument! First time out I was caught out by the sax player who decided after the soundcheck to move his instrument stand right next to the foldback speaker during the first number and got hit by the obvious feedback when he placed his instrument down before I could mute the channel! Have used them now live and in studio for brass, percussion and acoustic strings and found them to give a good all round performance, and well worth the money.
