Description
The PHD-A4F-150 is a dual-sided dynamic headset engineered for sustained comfort and clear voice transmission. This professional headset combines wide-band dynamic earphones with leatherette ear covers to improve fit and acoustic isolation. It is designed to deliver reliable audio and precise microphone placement for live production and broadcast environments.
Key features include a noise-cancelling dynamic microphone on a semi-rigid adjustable boom and wide-band dynamic headphone elements. The headset offers two impedance options across the PHD family and foam-backed leatherette ear covers for improved frequency response and isolation. The semi-rigid boom allows repeatable microphone positioning and reduces handling noise.
Technical performance includes a headphone frequency response of 200 Hz to 10 kHz and sensitivity ratings that differ by impedance: 98 ±4 dBSPL at 1 kHz and 1 mW for 150 ohm models and 100 ±4 dBSPL at 1 kHz and 1 mW for 300 ohm models. Microphone performance is specified as a noise-cancelling dynamic element with 200 ohm impedance, a frequency response of 200 Hz to 6500 Hz, and sensitivity of -63 ±3.5 dB re 1 V/Pa at 1 kHz. These specifications support intelligible speech reproduction and effective ambient noise rejection.
Connectivity is provided via XLR connectors matched to the model variant – including 4-pin female XLR options for power and intercom systems. The headset ships with an approximately 6 ft. cable measured from tip to ear shell to support flexible routing in control rooms and mobile carts. The design is compatible with standard intercom belt packs and production audio interfaces that accept the listed connector types.
Typical applications include broadcast control rooms, live event production, theater communications, and intercom stations where clear two-ear monitoring and robust speech pickup are required. The headset’s noise-cancelling boom reduces unwanted ambient pickup and stabilizes operator voice levels across noisy environments. Dual-sided listening improves situational awareness and consistent monitoring across long shifts.
Installation and daily use are straightforward thanks to the lightweight construction and adjustable headband that accommodates extended wear. The earphones are covered in leatherette to improve comfort and isolation while remaining easy to clean and maintain. The semi-rigid mic boom holds position during movement and allows quick adjustments without tools.
Overall the PHD-A4F-150 provides production-grade audio clarity, a noise-cancelling microphone, and a rugged, lightweight build suited to professional AV workflows. It balances comfort, durability, and technical performance for long sessions in demanding environments. The headset is a practical choice for AV professionals requiring reliable voice communication and consistent monitoring.
