I've used this mic with Sennheiser's SK-100 bodypack and EK-100 receiver. The audio clarity is good however it as noted in another review, it is very heavy on the mid-range.

Sennheiser has one of the cleanest sounds for microphones on the market. If you are concerned about your performance, this is the mic to get. The receiver can be used for multiple applications from the wireless body pack to the handheld mic to the individual instrument transmitter.
