included with the Rio 500 are 1 AA battery, a carrying case,
headphones, and other assorted goodies such as software and
Loaded with 64MB of built-in flash memory, and upgradeable to
96MB through the open expansion slot, the Rio is no slouch when
it comes to memory. With the included memory alone you can listen
to over an hour and a half worth of MP3s encoded at 128kbps
(near CD-quality). Using the optional 16MB or 32MB SmartMedia
expansion cards you can up your listening time an additional
20-40 minutes (give or take a few). In the near future Diamond
should also be releasing a 64MB flash card, bringing the total
possible memory up to a massive 128MB.
Rio's many included playback options give you everything you
could have ever wanted. The Rio stores all its MP3s in 'folders'
in which you designate through the included software. This feature
was especially cool, letting me organize my MP3s by type. All
folders can be played using repeat and random order functions,
or you can choose to play just single tracks or folders in any
order. The Rio also includes EQ customization for bass and treble
as well as four presets (classic, jazz, rock, normal). All these
options are set using the ultra-cool thumb-num wheel, which
doubles as a volume control.
