MP3 players are one of the most popular devices on the market these days, and the YP-20T "Baby-Yepp" is sure to capture the attention of a few. As far as portable MP3 players go, this has to be one of the smallest on the market, measuring only a scant 40x70x22mm. The 32MB (64MB also available) unit will hold from between 7-12 average sized MP3's at a good quality encoding. In our tests with the device, we managed to store about 7 songs that ranged in size from 2Mb to 7Mb - sound quality during playback was really excellent.

Yepp YP-20T Specs
	Processor: 12MHz, 16bit CISC Memory: 32MB Power: 1.5V Battery: AAA size (4-hours approx.) Dimensions: 42x70x22mm Case: plastic File Transfer Speed: 2.4Mbps Signal to noise ratio: 85dBa Earphone output: 5mW Frequency Range: 20Hz - 20KHz Manufacturer: Samsung Cost: $100USD

The YP-20T ships with a pair of headphones that double as a lanyard, a CD-ROM with Samsung's Yepp Explorer software, instructions, USB cable and a AAA battery. The unit is powered by a single AAA battery and will get about 4 hours of playback out of it. To transfer your MP3's onto the Baby Yepp it need only be connected via the USB cable to a computer with the Yepp Explorer software installed on it. The Explorer software shows information on the number of MP3's on the unit, their size and information regarding how much storage remains. Transfers to the onboard NAND flash memory take about 20-30 seconds for an average sized MP3 file.

As the unit only comes with built in flash memory there are no mechanisms for upgrading it, or increasing storage size however.

The Baby-Yepp is about half the size of an egg. Below, the headphones which double as lanyard.

Using the device is quite simple, though it will take a while to figure out a few key combinations necessary to shut the unit down. There are only four buttons on the device, which will easily fit in the small pocket of a pair of jeans. The LCD display indicates the song title and several other bits of info like the battery strength, and track number. Additionally you can use the play/pause/stop key to begin a track or shuffle through using the FF/Reverse keys which also double as the volume controls. Learning the various options associated with the menu key is important for easily navigating through the various menus that allow you to control volume or shut the device down.

The interface is a little less than intuitive, but functions quite well once you've picked up the right key combinations. It ships with a set of headphones that are integrated into a lanyard so the unit can be hung around your neck while exercising for instance. A small detachable clip holds the small player firmly in place. The sound quality through the headphones is quite good, but we preferred to use a pair of standard ear-bud headphones without the extra accessories.

Uploading music via the USB cable is really easy and with the Explorer software Samsung ship with the unit, adding or removing files is as easy as clicking and dragging. The unit also as some erase features built into it. Play back need not stop while the files are being transferred (so long as the process doesn't affect the song you are listening to).

All in all, the Yepp YP-20T is a really cool little MP3 player. Our only wish would be a for an easier way to shut off the power, but that is a minor point. I would however recommend getting the 64MB version as it offers more storage capabilities.

Granted this type of MP3 player is not meant for everyone (memory is not expandable). If you are the sort who has CD's full of MP3's to listen to you, would be better served by getting one of the new generation MP3-CD players. However for the person who only needs a small amount of MP3 storage during the morning jog, this incredibly small, and ergonomic device would be a good bet.
