When you hear the name TDK, you think of the recording process first and foremost. Well, here’s something that focuses on the playback end of the musical experience. It’s a pair of portable speakers called the Xa-10, and they’re flat and ready to slip right in to your purse or back pocket.

OK, so they’re not totally flat. The batteries in the middle make a bit of a bulky feel, but they are mostly flat, in the same way that a mobile phone is mostly flat. And they pump out a good bit of sound despite being only 4.6 inches tall.

They come in three colors: lime, orange, and silver. They connect to any stereo handily enough and pump out 1.2 watts. They’ll be available on March 20, although first in Japan, for a price of US$25.
