From the manufacturer:

Designed for smooth, natural vocal reproduction, ATM510 dynamic handheld microphone features a cardioid capsule that reduces pickup of sounds from the sides and rear, maximizing isolation from other sound sources and minimizing feedback. It is equipped with a rare-earth magnet for improved output and transient response, and has specially designed internal shock mounting for reduced handling and stage noise.

The microphone’s durable, all-metal construction ensures long-lasting performance, while its multi-stage grille design offers excellent protection against plosives and sibilance without compromising high-frequency clarity. Each microphone comes with an AT8470 Quiet-Flex™ stand clamp, a 5/8"-27 to 3/8"-16 threaded adapter, and a soft, protective pouch.
