Just when you thought we reached the limits of button technology, along comes Button 2.0. This is easily the first button innovation we can ever remember, and it happens to be pretty neat. Button 2.0 replaces a standard button with a button/headphone cord holder. It’s a standard shirt button except it has a little clamp on one side to allow you to pop your 2 mm (standard) headphone cord into it. It will slyly keep that swaying cord in line when you’re wearing a button down. It’s
easily the most exciting thing to happen to buttons since the most exciting thing to happen to buttons.
