The Sennheiser HMD 46 is designed for professional communication systems that require a lightweight headset, a noise-compensating Dynamic microphone, and flexible wearing options. It is well suited for intercom operations, radio broadcasting, and television production.
Sennheiser HMD 46 | Broadcast Headset with Dynamic Microphone for Intercom Systems
Sennheiser HMD 46 is a broadcast headset with an integrated microphone, designed for communication in intercom systems, radio, and television broadcasting. It combines Dynamic headphones with a noise-compensated Dynamic Microphone, helping deliver clear voice transmission in environments with significant background noise.
With a lightweight design weighing just 150 g, a flexible microphone boom, and an ear cup that can be rotated away from the ear, the HMD 46 is suitable for technical staff, production crews, and professionals who need to maintain communication over extended periods.
Noise-compensated Dynamic Microphone with Supercardioid Pick-up Pattern
The HMD 46 features a noise-compensated Dynamic microphone that helps improve voice clarity in environments with considerable background noise. Its Supercardioid pick-up pattern focuses on sound from the front of the microphone while reducing unwanted noise from other directions.
The microphone has a frequency response of 40 Hz – 18,000 Hz, making it suitable for communication and voice transmission in intercom systems. The microphone boom can be adjusted to either the left or right side to suit the user's wearing preference and equipment setup.
Dynamic Headphones for Clear Audio Reproduction
The headphone section uses Dynamic drivers with a frequency response of 16 Hz to 20,000 Hz, supporting audio monitoring during operation. The headphone impedance of 200 & OMEGA; and microphone impedance of 300 & OMEGA; are important specifications to consider when connecting the headset to intercom equipment or broadcast systems.
The HMD 46 has a maximum sound pressure level of 123 dB SPL. Total harmonic distortion (THD) is below 0.1% at 1 kHz, 100 dB SPL, according to the manufacturer's specifications.
Lightweight and Flexible Design for Extended Use
Weighing only 150 g, the HMD 46 helps reduce head fatigue during prolonged use. Its patented Two-piece automatic headband automatically adjusts to provide a suitable fit for the wearer.
The ear cup features a Flip-away design, allowing users to move it away from one ear to hear external sounds when needed. Soft ear cushions enhance comfort during use. The Single-sided cable design also makes cable replacement more convenient.
