iRiver has announced the launch of the DP250, its first MP3 player through recently acquired Siren. The player is branded as a Siren product but definitely has taken on the iRiver look. The Siren DP250 is a somewhat smaller MP3 player measuring 102mm x 30.5mm x 12.7mm. The DAP will launch in Japan September 7 in 1GB and 2GB capacities for $85 and $120, respectively.

It comes in colors of black or white, features a 4 line display and gives up to 18 hours of play time on a single charge. Aside from playing MP3’s the DP250 can record through a microphone, line-in or from the FM radio. What’s really interesting about this player, and probably what gives it some size, is that it has a built-in 400mW mono speaker. If doesn’t provide enough umph to share your tunes the player also has an FM transmitter that lets you share them through a nearby FM radio.
