Yeah, that is right. It is a microphone that is sound-proof. Unfortunately it isn t sound proof as in keeping you from hearing my drunk self from singing of Journey at the karaoke bar, but sound proof by keeping every other noise out of the microphone. The design appears to be a bit, awkward. But there is really no other way to section off your voice unless you just put a bag over your head. This is honestly a good idea, but it is probably damn near impossible to design a way to cut outside noise without looking like a damn duck-billed platypus. It'll be available for about $65.
