They sound pretty good.
Review for the "happymusic CM2 Professional Instrument Mic".
These microphones work well for recording. I don't recommend recording with vocals unless you also use a pop filter because they are very sensitive to plosives. (Shown in my video)
The biggest difference I noticed between the capsules was a proximity effect, like the cardioid and hyper cardioid sound deeper than the omnidirectional.
All of the capsules do well at not picking up ambient noise.
I had two issues with the set.
1. The mic holders are not tight enough and the mics slip.
2. One of my capsules has some glue on the grill. (See my video.)
Overall I like them, sound good and you get two which worked perfectly with my ESI Neva Due audio interface.
