Shure SM7B (1973)

The Shure SM7B is the broadcast-standard cardioid dynamic vocal microphone heard on countless podcasts and radio shows. It uses a balanced 3-pin XLR output and needs a microphone preamp with at least 60 dB of clean gain — its low –59 dBV sensitivity is the reason most users pair it with a Cloudlifter or FetHead inline booster. The integrated swivel mount has a captive 5/8"-27 thread for stands and boom arms.

Broadcast-standard cardioid dynamic mic with a 3-pin XLR output and very low sensitivity that demands a high-gain preamp or inline booster.
