Most: Condenser Microphone, cardiovascular capsule, complete with lines. filter and-10dB low cut, with frequency response for each microphone!
Delivered in a briefcase, with slider to couples XY and ORTF.

The -: I'm careful with my gear, I managed to break the suspension of a screw! (Metal poor quality ...)
These microphones are supposed to be paired ... their output level is not the same, and differences on some frequencies audible at times ...

OVERALL OPINION

I use this relationship for three months for over-head battery (in association with an SM57, a Sennheiser E604 Beta52A and 3).
For the price and quality comparison of the other mics on drums, I was expecting a report cymbals, ride, charlet sad ... and not at all.
These microphones reprennet much bass (cut with the switch and filter later) and are very accurate in the treble, and the lens of cymbals and especially the spring charlet good without being too aggressive (what I did not expect for the price!)

For the price, a pair of microphones bluffing! (Too bad the suspension is so fragile)
