Ersmtal for the price can not expect much one. It sounds better than any built-in laptop microphone or some cheap headsets. Nevertheless, I would not use it for voice recording;) Frequency response is deeply accented with faint details. Noise is clearly audible one must speak directly into it for a reasonably good sound. Problematic for a Ansteckmikro course. I do not use it and would recommend to spend a little more money for a real voice microphone.
The build quality is not good. Technically it's just a microphone capsule with a thin cord. In the price range but sonically better than many another microphone.
