Finally, here’s the third new portable MP3 player from Sony, the Walkman B-Series (we’ve posted about the S-Series and E-Series yesterday). Marked as an entry-level Walkman, the device does come with all the good things found on its siblings, including easy file transfer, integrated FM radio tuner, voice recorder, and support for wide-range audio formats (no video, folks), such as WMA and MP3. It also has a stylish design with an exciting illuminator that pulses in time with the music when the bass button is pressed. Pretty cool.

Regarding battery life, B-Series Walkman can stand up to 16 hours of music. Currently, two models with diifferent capacity are available: the NWZ-B133F (1GB, $45) and NWZ-B135F (2GB, $60). The former comes in black, red, and blue; while the latter replaces the blue one with pink color.
