iRiver iRiver E100

To transfer content to the device, you can download the free iRiver Plus 3 desktop software from the company's Web site, but you might not need it: Another option is to use Windows Explorer to drag and drop most content into the appropriate file on the player, which shows up as a drive when connected and set to data transfer mode. Alternatively, the unit supports PlaysForSure-compliant services such as eMusic.

The desktop software was useful for converting and transferring a couple of videos from my desktop to the E100. But iRiver Plus 3 couldn't handle several Windows Media Video files, and it wasn't clear why. Still, the converted YouTube video I played on the E-100's 320-by-240-pixel display looked clear, crisp, and faithful to the original.

The same cannot be said for music playback. Anything with lots of bass or percussion produced unpleasant buzzing effects at higher volume. The buzzing didn't go away when I switched to high-end earbuds, so I don't fault the uncomfortable set bundled with the unit. Corroborating my observations, the E100 earned a score of 70 on the PC World Test Center's signal-to-noise ratio tests (where a higher number means a cleaner signal); of the players we've tested recently, only the Archos 105 did worse.

My biggest complaints about the E100, though, involve its unintuitive user interface. The way to toggle between loop and continuous play modes, for example, was not obvious; and I also couldn't figure out how to turn off the FM radio. The 46-page manual bundled with the device proved helpful, but not many buyers will have the patience to leaf through it, and many of the E100's features should be more readily accessible.

iRiver makes some slick and stylish portable music and media players, but the E100 isn't at the top of the list. Between its unprepossessing industrial design, ho-hum audio, and difficult user interface, I didn't find much to recommend it.
