The NewKube MP3 player

Bluetree Electronics recently introduced the NewKube, perhaps the world's smallest MP3 player, measuring one cubed inch.  The NewKube ($33.90) is made with an aluminum body and has a touch screen for audio navigation and control. It offers up to six hours of playback in a single hour USB charge. The player has a removable microSD slot, and ships with a small tote bag, charging cord and headphones.

Convinced that the sound from the NewKube is "better than any music player on any smartphone," Bluetree Electronics is also touting the following features on the NewKube MP3 device:

    Lock button - to prevent accidentals

    Repeat button - not found in comparable simple MP3 players such as the iPod Shuffle

    Jump Folder - allows you to get to the specific song location, also not found in simple MP3 players like the iPod Shuffle.

    EQ Pre-sets - lets users select music settings for optimized playback of Pop, Rock, Classical music and other genres.
