Sennheiser Boom Mic HSP Essential Beige

Theatre-Grade Headset Microphone for Demanding Stage Productions

Engineered for productions both large and small, the Sennheiser Boom Mic HSP Essential Beige anchors an industry standard for hands-free vocal capture. This Beige boom pairs an updated KE 4 capsule with a highly durable, sweat-protected design, ensuring a brilliant, natural sound for every performance. It functions specifically as a replaceable microphone element for the modular HSP Essential neckband system, offering a reliable audio solution for presenters, broadcasters, and theatrical actors. The microphone's ultra-light 25 g construction adds virtually no strain to the wearer during extended corporate events or demanding theatrical runs.

Patented Umbrella Diaphragm and KE 4 Capsule Architecture

Inside the ultra-thin 4.8 mm microphone boom sits an updated KE 4 capsule, renowned for delivering warm nuances and refined audio quality across a 20 Hz to 20 kHz spectrum. What makes this component stand out is the patented umbrella diaphragm combined with a rubber sealing ring. This specialized dual-layer moisture protection prevents perspiration from compromising the internal electronics during rigorous theatrical routines or long broadcast sessions. The robust assembly ensures performers can focus entirely on their delivery, knowing the capsule remains securely shielded from humidity.

Acoustic Performance and Sound Pressure Handling

The acoustic parameters are tightly calibrated to handle extreme vocal dynamics without introducing unwanted distortion or clipping into the live mix. This sensitivity range ensures quiet dialogue and loud singing translate clearly to the front of house.

• Pickup Pattern: Omnidirectional — captures audio evenly from all angles, removing the need for precise boom aiming relative to the mouth.
• Maximum SPL: 148 dB — easily processes powerful belts and shouts without electrical saturation.
• The microphone maintains a clean signal floor requiring minimal noise reduction in post-production with an equivalent noise level of 30 dB (A-Weighted).

Wireless Connectivity and Modular Power Design

Designed for streamlined wireless setups, this module integrates seamlessly into professional transmitter packs without requiring external power supplies or phantom power routing.

• Connector Type: 3.5 mm TRS locking jack — provides a secure, physical attachment to the compatible neckband assembly and wireless belt packs.
• Cable Length: 1.3 m — offers enough routing slack for clean cable management down a performer's back.
• Power Source: Plug-In Power — draws the necessary bias voltage directly from the connected wireless transmitter system.

Physical Build and Environmental Resistance

Engineered to survive the physical demands of frequent wearing and harsh touring schedules, the physical dimensions maintain an incredibly low visual and physical profile on the human head.

• Capsule Diameter: 4.8 mm — maintains a low footprint that does not obstruct stage lighting or facial expressions.
• Net Weight: 25 g — keeps the entire headset assembly light enough for all-day wear without fatigue.
• This model is water-resistant and sweat-proof, guaranteeing reliable function in humid or demanding environments.

Ideal Applications for Voice-Over and Stage Professionals

This model is the right choice for theatre directors, broadcast engineers, and corporate AV teams who need a modular, durable headset solution. It is particularly well-suited for live musicals, houses of worship, and keynote speakers whose presentations demand absolute freedom of physical movement. By pairing this condenser boom with a compatible Sennheiser wireless transmitter, audio operators secure a complete, frictionless signal chain. Practitioners deploying gear in rigorous touring scenarios will deeply value the integrated moisture protection and rugged craftsmanship above all else.
