We first told you about these speakers back in September, but since everyone else is all gaga over them we thought we would remind you. JVC’s nano colored SP-A130 speakers are compatible with the nanos in size as well as color.

Just slide the cover out and you’ve got yourself a portable speaker with a 3.5mm input to connect it to your nano or other compatible portable media player. It’s powered by AA batteries and will be available this March for $29.95.

Here’s a different kind of slider from JVC Japan. The SP-A130 is exactly what it looks like, a sliding speaker. These portable active speakers are 30mm wide and will deliver stereo output up to 160mW×2ch. The case has a sliding mechanism which protects the actual speakers from dust and dirt.

The unit is powered by 4 AA batteries which will give you 16 hours of continuous play. The speaker also has a passive mode which allows it to draw power from the source.
