RTS PH-3 A5F Dual-Sided Binaural Headset / Full Cushion / Medium Weight / A5F Connector

Description

The PH-3 is a dual-sided binaural headset designed for clear two-ear monitoring in professional AV and broadcast environments. It pairs medium-weight construction with foam-filled full cushions to provide a comfortable fit and moderate isolation from ambient noise. The headset offers stereo audio reproduction and a balanced feel for extended use.

Key features include foam-filled cushions for user comfort, a dynamic noise-canceling microphone for targeted voice pickup, and an adjustable ball joint microphone mount for continuous positioning. Speaker sensitivity is optimized for clear monitoring at 95dB, and the headset maintains a practical frequency range for speech and program material. The design balances isolation and situational awareness for operators.

Technical performance covers an acoustic frequency response of 100 Hz – 10 kHz for the speakers and a microphone frequency response of 200 Hz – 6 kHz. Microphone sensitivity is -65 and microphone impedance is 150. Headset impedance is specified at 300 per side which supports common intercom and comms systems.

Connectivity is straightforward with A5F connector options and compatibility with A5M variants as required by specific beltpacks or panels. The cord length is 1676.4 mm (5.5 ft) to allow flexible routing without excess cable. The microphone uses a dynamic noise-canceling element and an adjustable ball joint for precise placement.

Typical use cases include production studios, live broadcast booths, field ENG teams, and intercom monitoring where clear voice intelligibility and operator comfort are essential. The PH-3 suits talkback, commentary, and monitoring duties in controlled and semi-controlled noise settings. Its medium-weight profile helps reduce fatigue during long sessions.

The headset is simple to deploy and built for regular professional use – foam cushions are replaceable and the ball joint mic allows repeatable positioning. The cable and connector choices match standard industry beltpack and panel connections. Overall the PH-3 combines practical audio performance, dependable microphone rejection, and an ergonomic fit for sustained operation.
