If you're going to be wearing them all the time, you may as well start thinking about it as an accessory right?
These precious earphone gems are Elecom's Ear Drops - embellished with sparkly bling (not real gems), you might not even have to wear earrings with these. The Ear Drops come in both black and white, and different shapes: the round shape (shown), a heart shape, and a design that has the sparkles along the length of the "stem." So far, I've seen them on sale for $35.79 a pair at GeekStuff4U.
The small amount of sparkle on earphones are subtle enough when it comes to your music. Just don't go plugging them into your handbag.
