You don’t see this kind of design on headphones everyday. It’s called the Street Headphone. It has a laser sintered polyamide outer shell, which is created using the rapid manufacturing process. That means you can personalize your own outer shell with something custom etched.
It can be lyrics, your name, or whatever you want others to read. The only problem is the price. The headphones will cost you about €833 (or $1,140). Some people don’t spend that much on a TV. But if you are in love with the idea, then go for it. Hopefully they last longer than most headphones for that price.
