As they say, all ingenious is simple. OliveBird, one of the users of the Shapeways website, a service where you can “print out” personally designed objects (currently not working due to Hurricane Sandy in New York), came up with the concept buttons with a holder for the wire from the headphones.
The idea is simple: on one side of the button there is a small clip, with the help of which a wire no thicker than 2 mm is attached. Now Button Button 2.0 can be purchased on Shapeways in several colors, ranging from $ 3 to $ 4 . ')
After such implementations of the simplest ideas, it is more and more believed that everything is not yet invented in this world, the main thing is a little imagination. Hopefully, the author patented his invention.
