Beyer Dynamic M640N 018104 and 018017 microphones


These were bought from eBay.fr.


Communication in French can be extremely polite.


Amazing microphones with sintered bronze mic cap.
Extremely small.
They sound very clear.
They do not need a Pleiades (R,L) filter.


As a stereo pair the sound is even more amazing.


No s problems.


Only perhaps con is that capturing a vocal from a larger distance may be more natural as one records all the head reasonances etc. But this argument is defeating the purpose of this mic.


So it may be a very suitable vocal microphone.
Perhaps even more suitable than on voice as speech may need more bass in order to sound natural.


Signal path:


male singing voice at mid to high register - M640N pair at 2in - (phase reverse adaptors if needed) - Sony TC-D5 Pro - Sennheiser HD580 - singer's ears, brain


The mic sounds very close to flat frequenc response from singer's vocal chords to listener's brain [Lowe, Morgan] if used at about 2in.
