Partner up with a designer/clothing company or a musician
Monster beats by dre
and the list goes on. For example you could partner up with a clothing company and have your headphones at their shops and they could make some tshirts with klipsch branding. I think the style of columbia clothing or jack and jones would really suit your headphones. Or partner with a company that makes cases like otterbox, elementcase, rokform and have a set like a stand with klipsch speakers or a sport case with heaphones.
