High-quality polarized condenser headmic with omni-directional pick-up pattern: Black steel wire cable with TRS connector

High-quality condenser omni-directional neckband mic for vocal and speech applications. Individually adjustable. Patented sweat-protected diaphragm. Easily interchangeable and combinable components thanks to modular design.

Black, steel wire cable with 3.5 mm mini-jack. Suitable for Sennheiser SK 100, SK 300 and SK 500 evolution wireless series bodypack transmitters. For wired applications, the headmic can be used with the intelligent MZA 900 P phantom power adapter.

High-quality permanently polarized condenser headmic with omni-directional pick-up pattern, designed for professional "hands free" applications. The adjustable neckband is visually unobtrusive and very comfortable to wear. The twelve available HSP 2 variants differ in color, size and connector.

For wireless applications, the headmic can be used with different Sennheiser bodypack transmitters, depending on the connection cable. For wired applications, the headmic can be used with the MZA 900 P / MZA 900 P-4 phantom power adapter.


The HSP 2 is now available in a revised version with a new attachment clip for the microphone boom. The new clip has a very rugged, closable design, providing an extremely secure fit of the microphone boom.
