Sennheiser Headmic 4 Condenser Neckband Microphone (Black)

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 corporate presenters, broadcast journalists, theatrical actors, and high-energy live performers who demand studio-grade vocal articulation combined with a highly stable, visually minimalist form factor.

Connector Note: Your description contains a slight cross-reference regarding terminations. Sennheiser splits this modular headset into two distinct versions based on your wireless bodypack hardware:

  1. Headmic 4 (Black EW) — Article No. 509495: Outfitted with a 3.5 mm locking TRS jack designed for evolution wireless (ew G3/G4), EW-D, and EW-DX bodypacks.

  2. Headmic 4 (Black 3-Pin) — Article No. 509498: Outfitted with a professional 3-pin LEMO connector designed for high-tier broadcast transmitters like the SK 5212, SK 6000, and SK 9000.

Aside from the detachable cable termination, both variations share identical acoustic capsules, chassis specs, and mechanical properties.

Key Architectural and Acoustic Attributes

  • KE 4 Cardioid Capsule Calibration: Equipped with Sennheiser's premium miniature KE 4 cardioid capsule, the headset offers high gain-before-feedback. By ignoring off-axis ambient sound from the rear and sides, it isolates the presenter's voice cleanly—even when standing directly in front of loud public address (PA) wedges or side-fills.

  • Twist-Proof Dual-Side Boom Arm: The ultra-slim (1.1 mm diameter) microphone boom arm is completely twist-proof and can be structurally detached and re-mounted on either the left or right side of the frame, depending on user preference or camera profile angles.

  • Fully Modular, Adjustable Architecture: The high-tensile, lightweight metal neckband frame can be adjusted smoothly to contour to varying head dimensions. Its modular format ensures that the cable, capsule boom, clothing clips, and ear hooks are easily interchangeable for field maintenance.

  • High-SPL Safeguards: The capsule tracks audio cleanly across a full wideband dynamic range, managing extreme performance peaks up to 143 dB SPL without digital clipping or 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.

Perfect for my use
Works as intended. Solid build quality and works with my Windows laptop through the USB C connection. I wish the product description would clarify that the USB ports do not support video.

Great in every facet
Color: Space grey
This thing works well. No complaints at all. haven't had any problems with heat, and it fits into your pocket but doesn't fill it up. This is a great value, especially if it's on sale and you need extra ports or an sd card reader or both I would encourage people to try it out!

This hub worked when others did not
Color: Pink, Color: Pink
I have an Asus Zenbook that's at least 7 years old (ancient by technology standards) and it has a very problematic USB hub. I love my laptop. It functions well except for the hub. I usually get OEM peripherals for my electronics. (I use PC and Android. I'm not a Mac/Apple user.) In the case of the USB hub for my Zenbook the Asus replacement hub is garbage with a 1 star review on Asus website with warnings not to buy because of how fast it stops working. The Asus hub I purchased 3 months ago stopped working after using it 3 or 4 times. That's unacceptable in my opinion. I have tried other brands including Belkin, Anker and 2 others that I do not remember. None of them would deliver power to my laptop despite claiming they would. So I decided to try this hub. I need an external hub for the multiple USB ports because the Asus has no ports on the Zenbook itself, and power delivery (in a perfect world when everything works properly) should also be able to go thru the hub to charge the laptop. On my laptop, there's only one USB-C port to connect either direct power supply or a hub. You can't have both connected at the same time unless the hub allows power transfer to laptop, which the other brand hubs that I tried wouldn't support that power transfer, much to my frustration. This hub is the first hub that I've tried that will actually power my laptop. (I also switched my power supply cable to a Thunderbolt, so the combination of the new cable with this hub works.) I use a wireless mouse with a dongle that needs to be plugged in. I have a digital voice recorder that plugs in directly via USB-A to transfer files to the laptop. I use SD cards in my camera and MP3 player that I need a hub to transfer that media onto the laptop. This hub will allow all of that. Every port works that I have tried on this Acer hub and this hub does the thing that the other hubs failed to do on my laptop. The power transfer was the big issue for me and this Acer hub solved the problem that several others including the OEM, Asus, failed to do. Because of how many months I have been dealing with the power supply problem, hubs not delivering what they promised and this being the only hub that did work, I rate this product at 5 stars. It's less expensive than the Asus hub that stops working immediately after purchasing. It has more ports than the Asus hub with the extra SD card reader that the Asus hub doesn't have. It's a heavier duty outer shell compared to the Asus. The cord is thicker and better protected compared to the Asus, so it reduces the chance for stressing or bending the cord in a way that could break the wires inside or break the connector away from the wires. It's just a better design overall, when compared to the Asus hub. I am extremely satisfied with this Acer hub and I would recommend it since it did the "impossible" task that no other brand could do for me. 5 stars, indeed.
