running 48V power supply
sold a couple in a suitcase
3 years that I use for shooting over head battery
I did not try a lot of little microphones but I had the opportunity to work with AKG, Shure, Audio-Technica, Sennheiser and many others and I think the price / quality ratio is more that excellent!
assé neutral small bump from 4500 kHz makes a soft sheen,
good momentum ... no need to push the preamp ...
short a good microphone.
