As you probably know, Apple’s iPod shuffle created quite a stir when it was introduced with no screen and no buttons. How are you really supposed to control it, after all? Of course, Apple’s innovative (and hampering, in some ways) solution was VoiceOver, a system that enables owners to shout commands and have it respond accordingly.Unfortunately, this svelte workaround presents a problem: you can only use the headphones which Apple ships with the shuffle, as no other headphones have that VoiceOver chip built
