Used for 1 year.
20 GB usb2, rechargeable battery industry by using the supplied transformer. LCD gray / blue.
Application: hard drive to give transport, mp3 player, voice recorder.

With the supplied microphone, I record directly to mp3 192 kbps, and the quality is correct.
To make the sound, there should be a micro worthy of the name, but I suspect that it is capable of doing TRS jack sounds good: Low noise level on converters, and direct encoding wav or mp3.
Only small default: no level indicator.
Self-correct: 6 8 recording.

There are at Rockbox, an alternative firmware level that seems a lot of iriver's default:

I tested and I tell stories.
I have a friend who has the H340, which is not bad, except that the loading of the bone is much slower.
