Hide-a-mic T-Shirt Holder
This is the most versatile of them all. The very small design can be placed behind a seam of a t-shirt. It is also usable as a small Tie-holder, in a scarf, with a stickie in a coat, etc, etc. You can even put it in a small windjammer to protect it against wind. The T-shirt-holder is easy to apply and delivers good sound quality.
