5. Diamond Rio 500

The Rio 500 is the second generation of Diamond's MP3 player. It's as small as a credit card and looks very nice. It can be used without consulting the manual, as everything has been placed logically. Both the little display and the sound quality are good.

The one and only disadvantage - except the high price of almost $ 280 - is the memory size of 64 MB. On the other hand, the Rio 500 can compensate this by its very small size. However, the playback will be finished after one hour. You may expand the storage capacity by adding a Smart Media card (up to 64 MB), but consider the costs. Such a card adds at least another $120, so that you pay about $ 420 for the whole enchilada. In my opinion that's too much money for mobility, even if the player is as small as the Rio.

If you like to do biking tours or if you regularly run large distances you should consider the Rio. There are no mechanical components in it, thus even the strongest impacts on your run will not stop the playback.
