CVSJ-1304-4GB is the newest MP4 player produced by Chinavasion and it measures only 4.5mm in thickness.
It features a 1.8-inch screen with a 168×128 resolution, a USB 2.0 port, a 2.5 mm headphone jack and a rechargeable battery. It recognized almost any audio format (MP3,MP4, ASF, WMA and WAV) and includes also an FM tuner.
I don’t know if this is the world’s tinniest device but that’s the manufacturer’s statement. If you find a smaller one let us know.
Until then, the CVSJ-1304-4GB will have a price tag of $39.55 and will hit the market as soon as possible.
