Noticed the man who stands on the pier announcing what ferry has arrived gets tired of holding his megaphone and when you speak to him you need to speak up
So these pants would have a megaphone stitched or fastened into the crotch just below where your legs meet your torso
Now all the user will
need to hold if the mic, the mic would clip on the pocket or belt when not in use and the coil cord would connect through your front pocket.
there is another benefit, the user would no longer be generating giant noise near his or her own head
and probably the vibrations could get to feel pretty good down there.
somehow the thought of announcing some public information from my groin seems like it would have some greater impact.
