Well i have H-340, should be exactly the same quality. FROM INT/EXT MIC: Honestly, i've only really recorded voices so far. It's really good, because it can pick up whispers from the othe side of the room and it's quite clear. Good depth to the sound. Musically, i've recorded my self playing the violin and it's not bad at all, but i think the distance, volume and positioning are very important. If u can nail that then u'll get really good sound. I mean it's obviously not cd quality but to just show people or record ideas etc. it should be fine. The mics are very receptive though. It's easy to get distortion.

Hope it helps
