Like, you put the earphone plugs into your ears, and start the music, and it plays.
I’m thinking of ones that have audio control and possibly a button to change songs (up and down), which would all be tiny b/c the thing’s in your ear.
Mine would also be waterproof, so you could use them while swimming laps or showering or white-water rafting.
Of course, I don’t know if we have the capability to make those. And teachers would hate it b/c you could listen to stuff in class w/o them knowing it. And they would be incredibly expensive. Still though, why not invent a pair?
Because some things shouldn’t be so small as to be easily lost or broken. If it falls out of your ear while swimming, then it is likely gone forever. There’s $120 you ain’t gonna see again.
Think about it – you’re talking about fitting some sort of storage medium, a power supply, an amplifier, and an mp3 decoder in the same amount of space currently used to house a wee speaker – and still having room for the wee speaker. Even if you could manage that (which is still a long way off) you’d still have mono sound, unless you managed to wedge a transmitter in there, too – to pair with another earbud containing a receiver, amp, power supply, and speaker.
I suggested a similar thing (though cooler) to my former company and they decided that the technology was already there to do it, thus it couldn’t be patented. And since they couldn’t patent it, zero interest.
