I was surprised how good this mic is. The self noise is very low, comparable to Mics costing £200 more than this one. The low end is very good, I think I detect a slight loss of mid range clarity, but it is more than adequate for my needs. I bought this as a back up for a Pro HD NXCam, and find that it provides a good signal without having to turn the Gain right up.
I might add than I am one of those irratating people that is not easily pleased, but I can honestly say that I don't know of a similar mic, with such good credentials!
