If you not gonna buy the Behringer KIT with this microphone, don't buy it.
1. Reason, not even a big membrane, it's small membrane about and it's more like Electret membrane
2. Reason, not 20,000 Hz maximum was about 18,000 Hz
3. Reason, It's very noisy
P.S I saw disassemble of after it arrives at me on youtube (From Russian) and can prove it
P.P.S VIDEO: I added to Link Direct Timecode where it's showing capsule
