Now being sold in Japan is another audio player from Siren. Considering no more than the design of the DP350 it doesn’t appear to be the most versatile of media players. This is mainly due to the 0.6-inches of width and 128×160 pixel 65k color 1.8-inch LCD, but in the same way as the DP250 (also released since iriver’s acquisition of the company), this is a DAP which provides an impressive amount of functionality when compared competing players.
Most of the popular lossy audio formats are taken care of as the DP350 will playback MP3, WMA (DRM10), Ogg Vorbis, and AAC (unprotected), in addition to video and pictures in MPEG-4, WMV, JPG, and BMP file formats. Both MTP and UMS (MSC) transfer protocols can be used and recordings can be made in WAV and WMA from direct line-in, FM radio, and built-in microphone.
