I am a live and recording sound engineer in Central California.  Recently I complimented the theater sound operator after hearing a local children's group performance.  The drama company (not the theater) had rented a Bodymics system for the show.  The engineer, who has done hundreds of theatrical shows, talked at length about how great the "Countryman" mics had sounded and how they were so immune to flex noises, etc.  I didn't have the heart to tell him that Bodymics doesn't rent Countryman mics.  It isn't a direct A/B comparison, but Bodymics lav and headset mics are obviously good enough to pass with a very experienced sound professional for some of the priciest and most highly regarded mics sold today. If he can't tell the difference, who in an audience would able to tell that the Bodymics microphones are not name brand mics that cost five to ten times as much? .... Jeff S.  CA
