Thanks to a (male!) friend of mine for finding a Japanese website that sells shiny, lovely in-ear earphones - http://www.elecom.co.jp/pickup/ear-drops4/index.html. (Click here for a translation courtesy of Google.)

The line is called “Ear Drops,” and the earphones come in three shapes: squares, circles (round type) and hearts.

They’re very pretty and I can totally see them co-ordinated in himegyaru style. Though I personally wouldn’t buy them because I’m simply not a fan of in-ear earphones.
