I ordered this lapel microphone for recording from my PC, and I am very unhappy: the sound is muffled, far worse than my headset I had to replace ...
Moreover, the recording level is low even with the hyper microphone 5 cm of my mouth ... What a disappointment!
I'll try to use it with my SLR, and my initial tests show that the record is correct (always with a muffled sound), however, do not buy especially not if you want to make the screencast or podcast.
