Description
The PHS-A4F-300 is a single-sided broadcast headset engineered for long-duration comfort and reliable talkback performance. It pairs a noise-canceling dynamic microphone with a super-lightweight passive headset design to reduce listener fatigue during extended shifts. Designed for studio and ENG environments, the headset balances isolation and breathability for clear communication.
Key features include a semi-rigid adjustable boom for precise mic placement and fully rotating boom placement for right or left side use. The earphone uses wide-band dynamic drivers covered in leatherette cushions that improve fit and passive noise reduction. Soft headband padding and pliable ear cushions further enhance comfort for daylong wear.
Technical specifications include a headphone impedance of 300 Ohms nominal with a frequency response of 200 Hz to 10 kHz for accurate midrange clarity. The dynamic microphone element provides a frequency response of 200 Hz to 6500 Hz and a sensitivity of approximately -63 dB re 1V/Pa at 1 kHz. These characteristics deliver intelligible voice reproduction and reliable noise rejection for broadcast talkback.
Connectivity is provided through a 4-pin female XLR connector compatible with standard intercom systems and party-line interfaces. The headset ships with a 6 ft cord measured to the ear shell to allow comfortable cable routing in studio or OB setups. The connector and cable choices ensure simple integration with existing RTS and third-party intercom stations.
Common use cases include studio production talkback, remote broadcast commentary, and control room monitoring where clear voice communication and comfort are essential. The single-sided design enables situational awareness when one ear must remain open to the environment. Broadcast engineers and commentators will appreciate the headset’s balance of isolation and environmental awareness.
Installation and daily use are straightforward – the semi-rigid boom can be positioned quickly and rotated to either side as needed. The headset’s light weight and padded contact points reduce pressure on the head during long sessions. Built from durable materials including stainless steel components, the unit is made to withstand professional use in production environments.
