T-shirt-holder – This is probably the most versatile of the four clips. The 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 Sili-pad in a coat, etc, etc. You can also put it in a small windjammer to protect it against wind. The T-shirt-holder is easy to apply and delivers great sound quality.
