RTS PHD-A5M-300 Double-Sided Dynamic Headset 300 ohm / Noise-Cancelling Mic / Adjustable Boom

Description

The PHD-A5M-300 is a double-sided dynamic headset designed for extended use in professional audio and broadcast environments. It pairs wide-band dynamic earphones with a noise-cancelling dynamic microphone to deliver clear incoming audio and intelligible voice pickup. The headset is engineered to provide daylong comfort and reliable isolation for critical listening.

Key features include a semi-rigid, fully adjustable boom that enables precise microphone positioning and improved speech intelligibility. The earphones use leatherette-covered cushions to improve fit and passive isolation while maintaining a balanced frequency response. The noise-cancelling microphone reduces background noise and focuses on the operator’s voice.

Technically, the headset is available in a 300 ohm impedance variant optimized for professional intercom and comms systems. The headphone frequency response is 200 Hz to 10 kHz and the microphone frequency response is 200 Hz to 6500 Hz. Sensitivity ratings are specified per impedance to aid system matching and level planning.

Connectivity is provided through industry-standard XLR connectors with the PHD-A5M-300 using a 5-pin male XLR termination for system compatibility. The cord is approximately 6 ft +/-4 in measured from tip to ear shell, offering sufficient reach for most console and beltpack setups. The headset is finished in black and stainless steel to match professional racks and consoles.

Typical applications include broadcast control rooms, live event comms, OB vans, and studio talkback where reliable speech clarity and operator comfort are required. The semi-rigid boom and adjustable headband make it appropriate for users who need repeatable microphone placement and consistent audio capture. The passive isolation and leatherette ear cups help reduce ambient noise in noisy production environments.

Installation and day-to-day use are straightforward – the headset connects to standard XLR-based comms systems and requires no power supply for its dynamic elements. The build balances lightweight construction and durable materials to support long shifts without excessive fatigue. Overall, the PHD-A5M-300 delivers dependable audio performance and ergonomic comfort for professional AV and broadcast workflows.
