Rio Karma


Rio invented the MP3 player as we know it (back when the company was known as Diamond Multimedia), and it continues to innovate in this currently crowded space. The 20GB Rio Karma is its top-of-the-line player.

Hand-friendly design. Leader in codec support. Very good ergonomics and navigation. Ethernet on docking base.

Surprisingly thick. No belt clip or holster. Audio performance could be better.

This is a portable player that Rio seemingly discourages you from carrying, but comprehensive codec support and decent audio performance make it a favorite.

Review of the Rio Karma


Pocket Lint review of the 20GB Rio Karma, the MP3 player that seems to have emerged as the first runner-up to the iPod's pagaent winner. Yeah, isn't quite as minimalist or whatever as the iPod, but it does cost a lot less and have a bunch of...

Simple 20GB hard-drive player includes ethernet port and sounds great.

Unique features like Rio DJ, the ethernet connector, and support for multiple codecs--plus excellent sound quality and battery life--compensate for this attractively priced unit's shortcomings (such as no FM receiver, remote, or case).

While most vendors rush to cram more stuff into their hard-drive-based MP3 players--from FM receivers and transmitters to voice recorders and miscellaneous digital inputs--Rio takes a different tack with its Karma. The device comes with a handsome...

Music sounded crisp, clear, and plenty loud through the included Sennheiser MX300 earbuds, which are a small step above what vendors usually include with players. Similarly, the Karma's rechargeable battery was a notch more powerful than the norm: One...

Rio Karma 20Gb MP3 Player review


If you are going to go up against the iPod, whether you like it or not you have to not only offer what the iPod is offering, but because it is so loved by it seems everyone you have to put out all the stops to make that leap forward. Luckily for the...

Matches the iPod’s basic capacity; USB2.0 or Ethernet

Only the launch price

However that ever-dropping price stays near the iPod, giving true choice and taking capacity off the checklist- unless you already have a ‘Pod, that is.

Expert review by:

Rio Karma


Most hard-disk MP3 players try to ape the svelte design of the Apple iPod, but the Rio Karma is confident enough to stay in a class of its own.

Although it looks great and is a wonderful concept, the actual implementation of the MP101 falls well short of the mark.
