A drummer from a band I had used one of those types of mics.
He hated it after awhile. The cord was always getting in the way and the sound quality sucked, despite the $130.00 price tag.
The sound quality for any type of headset mic doesn't get decent until you get in the $200.00 and up range.... (so I am told).
Unless he's got the $$ to spend, he's better off with a SM57 and a boom.
