First off, the nice/great things about this player: 1)...You'll buy this for the speakers, and rightly so..they're great. It has the standard sound  dial from 0 to 10..and I play it around 5-6 in my place, 8-9 outside (and  it works great even in a downtown enviro, too..you CAN easliy hear it.)  They're only a bit 'tinny'..the cabinet speakers have no bass boost, but  that's because they're so small. Really, you don't need it. (NOTE...when  using headphones you CAN have a bass boost and a 'Train' setting..a more  muted version of bass boost. Just not when using the built-ins.) 2)... The  player size/design...very cool. I prefer the LCD display on top like this,  for easier read of the track & sound features. Button layout is nice  and easily memorizable.  3)...Has an energy saver feature where you can  make the batteries last longer...very noticable! 4)...40 Sec reader/skip  protection...this player WILL NOT SKIP. ------------BAD  THINGS...------------------ 1). Even if you press the 'hold' switch, the  player can still open. That's no good to me. Same with the  speaker/headphone switch. Using this player with headphones in a public  area, be acareful not to bump into that button and switch the speakers  on..that's embarrassing. 2.) No 'Groove' sound equalizer like on most Sony  machines. 'Groove' is by far the coolest sound system, next to the older  Sony player, the turtle-esque D-844K.(It had SURROUND SOUND..on a  Discman! ) 3.) Display DOES NOT LIGHT UP, even with ac pack used. That  sucks frog butt. 4.) The worst thing about the player...in a quiet place,  using either any headphones (I prefer Sony's 'street style' silver  wraparounds), or the built in speakers, you can hear a VERY annoying whine,  like from a TV set. (You can hear it when the player's set to a lower  volume setting easier than a louder one.) Using this player to fall assleep  with may be nervewracking because of this. You can clearly hear it with the  built-ins. Outside, or in a more 'active' area other than a quiet room this  'whine' is next to non-existent, however.
