The microphone is great, but not suited for all applications. It needs to be connected to a phantom power 48V (e.g. a mixer with this facility), otherwise it won't work at all. So beware if you want to use it as a 'normal' microphone on a karaoke, amplifier or even your computer for speech recording, the microphone will be dead!
This fact is a bit hidden in the specification list. It would be better be listed in the main description. I got fooled by this, and probably others will be too. While a great product, it didn't suit my purpose, and I need to buy another microphone.
