Chinavasion isn't known for offering up cutting-edge gadgetry -- far from it, to be honest -- but the MP4 player known only as the CVSJ-1304-4GB is actually fairly notable. According to the dodgy specifications, the $39.55 device checks in at just 4.5-millimeters thick, which is certainly thinner than the other so-called "world's thinnest" DAP. Of course, this may only be true due to the "MP4" moniker, seeing as most units not created and sold exclusively in China are called "MP3" players. Semantics aside, the unit also includes a 1.8-inch display with a 160 x 128 resolution, a curious 2.5-millimeter headphone jack, a USB 2.0 port and a rechargeable battery. So, do any of you have a competitor that's a hair thinner? Our hunch is yes.
