"The Yepp YP-MT6Z goes for a remarkably affordable price compared to just a year or two ago, given its 1GB of internal flash memory. Furthermore, in a rare move of consumer friendly design, the Yepp YP-MT6Z is powered by a single AA battery that will last for upwards of 42 hours (straight playback). Long battery life and inexpensive AA batteries are probably one of the greatest attributes of this MP3 player; heck a AA battery is even included! About the size of a pack of Wrigley's gum, the Samsung Yepp YP-MT6Z incorporates a digital FM Tuner with 20 pre-sets, inline MP3 encoding, a voice recorder and eight EQ pre-sets. It plays MP3, WMA, ASF, Secure WMA and Ogg Vorbis music files. Supported MP3 bit rates are 8 kbps - 320 kbps, and 48 kbps - 192 kbps for WMA files."
