Sennheiser HSP4-EW - CARDIOID MICRO HEADBAND - ANTHRACITE

A Solution Dedicated to the Wireless Systems of the evolution wireless Range

Designed for professional "hands-free" applications, this headset microphone naturally integrates into a setup based on a pocket transmitter from the evolution wireless series. Its lockable 3.5 mm Jack connector secures the connection and minimizes the risk of false contacts during dynamic performances. The whole system aims for reliable daily use, with a design made for the field: quick assembly, secure wear, and replaceable components to extend the equipment's lifespan.

Another advantage of its versatility: it can also be used in wired configuration with the MZA 900 P preamplifier, convenient for switching from a wireless stage setup to a fixed installation (conference, place of worship, multipurpose room) while maintaining the same wearing comfort and microphone placement.

For Stage, Spoken Voice, and All Performances Where Hands-Free Use Is Required

This microphone is intended for professionals who need to speak, sing, or present without being constrained by handheld use: hosts, speakers, trainers, actors, event presenters, or technicians seeking a discreet and effective solution. Thanks to its very good intelligibility, it highlights articulation and presence, facilitating audience understanding even in complex acoustic environments.

In live situations, its performance-oriented design helps maintain an exploitable sound with minimal effort at the mixing console: the feedback rejection improves stability when stage monitors and sound reinforcement are close, and the low self-noise makes the signal cleaner, especially at close mouth distance or with processing (EQ, compression) typical of spoken voices.

Comfort, Precise Placement, and Reliability: Designed to Work Fast and Well

Ultra-Thin and Adjustable Gooseneck

The gooseneck is flexible and adjustable in length and angle to optimize capsule placement as close as possible to the mouth without compromising comfort. Its very thin format (2 mm diameter) remains discreet on camera while offering precise adjustment to fit morphology and performance style (energetic speaking, singing, public presentation).

Right or Left Positioning

The gooseneck is interchangeable and can be placed on the right or left side. This detail makes all the difference during performances: each user can adopt the most natural side, avoid rubbing (hair, beard, glasses), and maintain comfortable vocal emission over time.

Protected Capsule and Secure Connection

The capsule includes integrated wind protection, useful to reduce air noise and certain plosives in the voice while maintaining clear reproduction. The lockable 3.5 mm Jack connector provides additional security: once locked, the cable stays in place, reassuring during live situations (movement, quick changes, handling of the transmitter body).

Removable, Replaceable Cable: A Real Plus for Professionals

The removable cable is a key element for intensive use: in case of wear or maintenance needs, it can be replaced without immobilizing the entire microphone. In a control room, company, or rental inventory, this approach limits downtime and simplifies equipment management.
