Sennheiser HSP 4 Boom Microphone

High-quality permanently polarized condenser headmic with cardioid pick-up pattern, designed for professional "hands-free" applications. The adjustable neckband is visually unobtrusive and very comfortable to wear. The twelve available HSP 4 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 (see "Variants"). For wired applications, the headmic can be used with the MZA 900 P / MZA 900 P-4 phantom power adapter.

The HSP 4 is now available in a revised version with a new attachment clip fort he microphone boom. The new clip has a very rugged, closable design, providing an extremely secure fit of the microphone boom.

HSP neckbands equipped with the previous attachment clips can be retrofitted with the new ones which are available as spare parts.
