Sennheiser HSP 4-ew Headworn Microphone
The HSP 4-ew is a lightweight headworn microphone that puts a cardioid condenser element right at the corner of the mouth, so the wearer's hands stay free and the level stays constant no matter how they move. The permanently polarized MKE platinum capsule delivers the clear, natural speech Sennheiser built its reputation on, and the cardioid pattern rejects sound from the sides and rear to hold off feedback on a live stage, in a lecture hall, or in a house of worship.
This is the same microphone as the HSP 4 but terminated with the ew (Evolution Wireless) connector, so it plugs straight into a Sennheiser evolution bodypack transmitter. The adjustable neckband is slim and stays put through active presenting and performing, and the mic is finished in black.
