Munitio SITi bullet headphones are machined from a solid piece of high density copper to look like bullets.
The $160 bullet headphones have 9mm neodymium drivers. Instead of using gold—like its more expensive predecesor—these are coated in Titanium, silver- or golden-colored for a perfect gangsta look. [Munitio]
