iRiver has recently launched another new player through their recently acquired Siren brand of products. September brought their first with the DP250 and now they have released a slightly higher-end sibling called the Siren DP350. Unfortunately these Siren units are only retailing in Japanl.

The DP350 features a 1.8-inch LCD and uses it to show MPEG-4 video and still photos. It also supports audio of MP3, WMA, AAC and OGG. It also houses an FM tuner and direct in-line recording. An internal battery brings it 18 hours of music playback or 5 hours of video playback. It measures only 73.2×41×14.6mm which is a little smaller than a standard deck of cards and appears to have a pretty nice graphical interface navigated by buttons below the screen.

The DP350 comes in colors of black or off-white and will go for Yen equivalents of about $118 for a 2GB model or $153 for a 4GB capacity with the same features.
