Product Overview

The Sennheiser SL HEADMIC 1 is a premium SpeechLine digital wireless neckband microphone combining the broadcast-legendary MKE 1 subminiature omnidirectional capsule with an ultra-lightweight adjustable neckband frame weighing just 7 grams. Designed for TV presenters, conference speakers, theater performers, and anyone who needs pristine audio pickup with near-invisible on-camera presence, the SL HEADMIC 1 delivers the audio quality of a professional lavalier in a completely hands-free, secure neckband configuration. Operating over the 1.9 GHz DECT spectrum, it integrates seamlessly into the Sennheiser SpeechLine Digital Wireless ecosystem. Available in beige, black, and silver to match a wide range of skin tones and wardrobe requirements.

Product Description

The MKE 1 microphone capsule at the heart of the SL HEADMIC 1 is one of the most respected miniature microphone elements in professional audio. Used for decades on broadcast sets, theater stages, and live event productions worldwide, the MKE 1 captures voice with exceptional transparency, natural frequency response, and the consistency required in demanding professional environments. Its omnidirectional polar pattern provides smooth, even pickup regardless of slight head movements, eliminating the level inconsistencies that trouble directional headset microphones.

The neckband frame positions the MKE 1 capsule at the optimal distance from the mouth for level and intelligibility, while the adjustable design ensures a comfortable, secure fit for any head size. The frame is constructed from metal for lasting durability despite its featherlight 7-gram weight, making it equally suited to multi-show theater runs, all-day conference deployments, and quick-turnaround TV production. The included soft carry case holds both the SL HEADMIC 1 and a SpeechLine bodypack transmitter, keeping the system organized and protected between uses.

The SL HEADMIC 1 uses a standard 3-pin locking mini-XLR connector (Sennheiser SpeechLine pin configuration), making it directly compatible with SpeechLine Digital Wireless bodypack transmitters. The 1.9 GHz DECT operating frequency provides interference-free operation in congested RF environments where UHF spectrum is heavily used, and the SpeechLine system as a whole is engineered for plug-and-play simplicity with enterprise-grade reliability.

Frequently Asked Questions

Q: What is the difference between the SL HEADMIC 1 and SL HEADMIC 1-4?

The SL HEADMIC 1 uses a standard 3-pin locking mini-XLR connector for Sennheiser SpeechLine bodypacks. The SL HEADMIC 1-4 variant uses a 4-pin connector configuration for a different transmitter pin assignment. Always confirm connector compatibility with your specific bodypack transmitter before ordering.

Q: Is the MKE 1 capsule the same as the standalone MKE 1 lavalier?

Yes, the SL HEADMIC 1 uses the same MKE 1 subminiature omnidirectional capsule element found in Sennheiser's standalone MKE 1 clip-on lavalier microphone. This is the same capsule trusted in broadcast and film production worldwide.

Q: Can the SL HEADMIC 1 be used with non-SpeechLine transmitters?

The SL HEADMIC 1 uses a locking mini-XLR connector with SpeechLine pin configuration. It is designed and recommended for use with Sennheiser SpeechLine DW bodypack transmitters. Adapters may exist for other systems but are not officially supported; consult a dealer for compatibility guidance.

Q: Is the neckband size adjustable for different head sizes?

Yes. The neckband is adjustable to fit a wide range of head sizes comfortably. The flexible metal frame allows for customization while maintaining its shape over extended use periods.

Q: How does the 1.9 GHz DECT spectrum benefit my installation?

The 1.9 GHz DECT band is largely free from the heavy UHF congestion common in urban venues, convention centers, and broadcast facilities. It provides reliable, interference-resistant wireless operation without requiring UHF frequency coordination or FCC licensing for most professional uses in the US.

Q: What colors are available and which is most popular for TV use?

The SL HEADMIC 1 is available in beige (BE), black (BK), and silver (SB). Beige is typically favored for on-camera TV and broadcast work as it blends with a wide range of skin tones and is virtually invisible on screen. Black is preferred for theatrical applications with darker wardrobe.

Q: What receiver is required for the SL HEADMIC 1 system?

The SL HEADMIC 1 microphone works with Sennheiser SpeechLine DW bodypack transmitters, which pair with SpeechLine Digital Wireless receivers such as the SL MCR series. The complete system operates on the 1.9 GHz DECT protocol.

Q: Does the SL HEADMIC 1 require phantom power?

Power to the MKE 1 capsule is supplied by the SpeechLine bodypack transmitter via the locking mini-XLR cable. No external phantom power supply is required; the bodypack provides the necessary capsule bias voltage automatically.
