iRiver is back with two new MP3 players, the M31 Shining and M41 Revolve. The entry-level iRiver M31 also functions as a USB storage device, which is handy. It features a tiny OLED screen (128 x 32) and supports MP3, WAV, and WMA file formats.
The iRiver M41 has a larger 1.8-inch display and supports both audio and video playback. The M41 supports MP3/WMA audio files and AVI video files. The battery will deliver up to 15-hours of continuous audio playback or 4-hour of continuous video playback.
