RTS PHD-A4M-150 Double-Sided Dynamic Headset 150 Ohm / Noise-Cancelling Mic / 4-pin Male XLR / 6 ft Cord

Description

The PHD series double-sided dynamic headset delivers clear two-ear monitoring and reliable voice pickup for broadcast and live production environments. It combines high-quality dynamic earphones with a noise-cancelling microphone to ensure intelligible talkback and intercom communication. The headset is engineered for long periods of wear and offers stable isolation and consistent frequency response.

Key features include wide-band dynamic earphones rated at 150 Ohm impedance, a semi-rigid adjustable boom for precise mic placement, and leatherette-covered ear cups for improved fit and passive isolation. The noise-cancelling dynamic microphone reduces ambient noise and supports consistent vocal clarity. The headset is available with a 4-pin XLR connector option and a rugged 6 ft cord.

Technical performance delivers an earphone frequency response from 200 Hz to 10 kHz and sensitivity of 98 +/-4 dBSPL @ 1 kHz / 1 mW for the 150 Ohm configuration. The microphone is a dynamic noise-cancelling element with 200 Ohm impedance, a frequency range of 200 Hz to 6500 Hz, and sensitivity of -63 +/-3.5 dB re 1 V/Pa @ 1 kHz. These specifications provide reliable monitoring levels and dependable mic performance in noisy environments.

Connectivity is provided via industry-standard XLR connectors – the PHD-A4M-150 uses a 4-pin male XLR termination. The cord length measures 6 ft +/-4 in (1.8 m +/-10 cm) from tip to ear shell, offering adequate reach to belt packs and intercom interfaces. The headset is compatible with typical broadcast intercom systems and XLR-based audio talkback gear.

Typical applications include broadcast studios, ENG/OB production trucks, intercom and talkback systems, and live event communications where two-ear monitoring and a noise-cancelling mic are required. The headset’s isolation and adjustable boom make it suitable for operators who need precise mic placement and clear incoming audio. It is also appropriate for production teams working in moderate ambient noise conditions.

Built with a semi-rigid boom and leatherette ear cups, the PHD headset balances durability and comfort for extended shifts. The lightweight assembly reduces fatigue while providing rugged connections and dependable mechanical adjustment. Overall, the headset offers a practical combination of ergonomic design and audio performance that supports professional AV and broadcast workflows.
