Bad idea

I’ve been thinking of what to make my headphones from. Not just the innards, but the structure. I mean, if I wanted a crap looking pair of earmuffs with speakers, I could just go hogging at Best Buy.
I want something chill looking; I want my logo backlit; I want a statement of belief and fashion.
I want beer bottles.
I want beer bottles.
Now, admittedly I have a lot of them, and when all you have is empty beer bottles, every problem looks like unrecognized alcoholism. But seriously.
Beer bottles.
Figure I’ll put together something passable in terms of electronics in the requisite diameter, make sure it sounds decent. Take that, measure the height and get to cutting. Of course, they’ll be heavy as a duck, be a massive breaking hazard, next to my jugular, be a talking point which its I’d because I don’t talk. But they’ll also be the bomb.
Now about the head band…
