JVC Kenwood's new micro system NX-PB30 is 31cm wide and only 8.5cm long. It is scheduled to be released in early December.
NX-PB30 is compatible with CD, FM/AM radio, and MP3/WMA music files in USB memory. It also supports Bluetooth 2.1+ EDR (Profile A2DP/AVRCP, Codec SBC) so that you can play music in Bluetooth compliant devices wirelessly.
There is a Sound Mode function built-in for you to select your favorite sound quality out of 5 kinds (Classic, Rock, Pop, Jazz and Bass Tone) depending on your feeling.
