Sennheiser Headmic 4 Condenser Neckband Microphone (Beige)

The Sennheiser Headmic 4 is a premier, ultra-lightweight permanently polarized condenser neckband microphone engineered for elite vocal and speech applications. It is widely used by theatrical actors, house of worship worship leaders, corporate presenters, and broadcasters who require maximum visual discretion alongside professional audio performance.

Connector Configuration Note: Your description lists both "EW" and "3-Pin". Sennheiser splits this modular beige headset into two separate factory models based on the required cable termination:

1. Headmic 4 (Beige EW) — Article No. 509494: Includes a detachable 1.6m cable terminated with a 3.5 mm locking TRS jack for evolution wireless (ew G3/G4), EW-D, and EW-DX bodypacks.

2. Headmic 4 (Beige 3-Pin) — Article No. 509497: Includes a detachable 1.6m cable terminated with a professional 3-pin LEMO connector for top-tier broadcast bodypacks such as the SK 5212, SK 6000, and SK 9000.

Both variants share the exact same high-performance capsule, mechanical chassis properties, and beige finish.

Key Architectural and Acoustic Attributes

• KE 4 Cardioid Capsule Calibration: Built around Sennheiser's premium miniature KE 4 cardioid capsule, the headset rejects off-axis acoustic feedback. By ignoring ambient bleed from the rear and sides, it keeps the presenter's voice isolated and clean, even when working on small stages with high environmental volume or loud PA wedges.

• Discreet Flesh-Tone Aesthetic: The entire frame, cable jacket, and capsule housing feature a low-reflection beige finish. This allows the assembly to blend seamlessly against skin tones on camera or under theatrical stage lighting, remaining visually unobtrusive to the audience.

• Twist-Proof Dual-Side Boom Arm: The ultra-slim (1.1 mm diameter) microphone boom is completely twist-proof. Thanks to the system's modular architecture, the boom can be quickly unclipped and re-mounted on either the left or right side of the frame to accommodate specific profile angles.

• High-SPL Resilience: Engineered to handle powerful vocals and shouting speakers, the capsule processes signals smoothly across a wide dynamic range, tracking extreme peaks up to 143 dB SPL with zero internal diaphragm saturation.

Fitting and Field Application Advice

Optimal Proximity Placement: Slide the adjustable neckband on so it rests securely around the back of the skull. Bend the flexible boom arm gently so the KE 4 capsule sits roughly 2 to 3 cm from the corner of the mouth. Do not place the microphone capsule directly dead-center in front of the lips; offsetting it prevents breath bursts ("P" and "B" plosives) from hitting the element directly.

Keep Stress Off the Connection: The 1.6-meter cable is built to handle active movement, but it should never be pulled taut. Always leave a tiny amount of loose slack loop near the base of the neckband before routing the wire down the talent’s wardrobe to their bodypack transmitter. Secure the cable with the included clothing clip to absorb sudden body tugs and minimize cable handling noise.
