I use it for 4 months now and I redcouvre the joys of music on the go.
The Iriver H10 is equipped with a mini hard drive of 5 GB (new version Pipelines Limited with 6 GB), radio, and even a dicatphone a photo viewer.

It supports MP3, WMA, JPG and TXT files and can store what you want it.

Rgonomie level I find it very practical and navigation is easy, in spite of dconcertante sometimes a few delays.

It fits in any pocket (even small) and the quality of sound is irrprochable ... Ms. headphones provided is correct! (Sennheiser MX400).

In short a good product.
