There are numerous advantages to currently available MP3 players over previously hailed media players. The first and probably most noteworthy would have to be the sheer small size in comparison to a walkman or Discman. The Samsung Yepp YP-35H weighs in at a measly 1.04ounces and its size is a small and compact 66.5mm x 45mm x 16.5mm. The other notable advantage to MP3 players is that the unit has no real moving parts; this dramatically increases the unit’s battery life. The YP-35H utilizes 1 (one) AAA battery and has a battery life of 15Hrs.
