Little Sony earphones make lots of noise

Sony's out with a new set of little earbuds designed to deliver the big notes.


The MDR-EX90SL earphones feature a 13.5-millimeter sound driver. A driver that size wouldn't fit into the ear, so Sony has attached it diagonally to a smaller 9-millimeter swiveling tip that does fit in the ear canal (see attached photo for a closeup). Because that swiveling tip is attached to a driver that can pump 5 to 25,000Hz of audio, you're getting a whole lot of sound.

The in-ear headset will hit the Japanese market May 10 for 11,800 yen ($104).
