while working out, I wear it with the supplied beltclip, clipped to the waste band of my shorts. I wear on the back to the right side, just above where I'd wear a wallet. The head phone cable runs up my back and over the shoulders. My shirt covers the mini for the most part.
Other times, I'll just wear the mini without belt clip in the small coin pocket of my jeans. It fits just right, as if it was made for eachother. Again my shirt usually cover the mini, except for a few flashes of green when I move or stretch.
