I mainly use a sound recorder to the sounds of nature in a very quiet atmosphre.
My opinion is that of a casual amateur.
I use a Sony DAT TCD rgulirement-D8 + Microphone Rode NT4

Please note this test was done only to headphones connected to the recorder, I did not TRANSFR files on PC.
Sennheiser HD600 and HD25

- How long have you use it?
I was testing the Zoom H2 for a few days

- What is the particular feature you like most?
Overall complete and successful.
The unit is compact homogne trs, self-satisfaction with NiMH 2900mAh.
Easy to use, you soon realize all the functions without using the manual.
Intgr mics are good.
Good rsultats to loud sounds or means.

- What is the particular feature you like least?
Breath important depending on the level of amplification, level 3 on the Zoom H2.
1st level low blows, but bearable Submitted enough 2nd, 3rd breath important.
LCD display readable medium on the day in the sun characters too small.
Trs fragile little plastic bumps and scratches.
Headphones to its terrible.
The Rode NT4 branch does not work on the Zoom.
Lack of effect stro.
Lack of "transparency" or "ism" from my Sony DAT TCD-D8 + Rode NT4.
Sounds in the acute power shortage of bass.

- How do you report qualitprix?
Trs good value quality / price

- With the exprience, you do again this choice? ...
Yes, lightweight hsiter to travel, spend inaperu.

For reasons of budget, I changed the zoom H2 to a fostex FR2 LE, compltement that satisfies me, much better than my old DAT.
