Audio-Technica U857QL Cardioid Condenser Quick-Mount Gooseneck Microphone Overview:

The 18.94" version of the U857Q, the U857QL cardioid condenser quick-mount gooseneck microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. It features an ultra-flexible small-diameter gooseneck and accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. Equipped with self-contained electronics, the phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
