Sennheiser HSP4-3-5 Headworn Microphone

The Sennheiser HSP 4 is a headworn condenser microphone built around the cardioid MKE platinum capsule, the permanently polarized element Sennheiser relies on for demanding hands-free work. It rides on a lightweight neckband with a slim boom arm that holds the capsule a fixed distance from the mouth, so levels stay even as a presenter, instructor, or performer moves around. The cardioid pattern favors the voice and turns away room reflections and stage wash, which helps hold off feedback in reinforced rooms.

This is the beige HSP 4-3-5 version, terminated with an open-ended pigtail and no connector so it can be wired to the bodypack of your choice. It handles up to 150 dB SPL and runs on 4.5 to 15 V. The mic ships in a foam-lined plastic transport case with the neckband, boom microphone, connection cable, and operating instructions.
