Sennheiser HSP 4-EW-3 Cardioid Headset Microphone – Neckband Condenser
This lightweight Cardioid Headset Microphone is a headworn (neckband) condenser mic built for hands-free speech and vocals in presentations, theatre, houses of worship and live performance. Its cardioid MKE capsule helps reject feedback and ambient spill, while the adjustable neckband and thin boom keep it discreet on camera. The 'ew' version connects to Sennheiser evolution wireless bodypack transmitters.
