Samsung plans to unveil this week at CES an iPod-Nano competitor MP3 player called the YP-Z5. The gadget offers storage between 2 and 4 GB, has a 1.8-inch screen and boasts great 3D sound. It also reportedly gets about 38 hours of battery life. (The photo below is of the YP-Z5.)

Another Korean company, called Mannetel, will roll out their EXQ at CES. The EXQ is Yet Another MP3 Player, but features a useful gimmick: The headset can be left in your ears and used to take calls from your cell phone via Bluetooth.

Personally, I don't think any company has a chance in hell of unseating any of the iPod models. Apple is perfectly unstoppable for now -- especially in the wake of an unbelievably successful holiday season -- but that's not going to stop Korean and Chinese companies from unveiling a huge variety of MP3 players at CES -- with every single one of them designed to steal market share from Apple.
