RTS PH-3 A5M Dual-Sided Binaural Full-Cushion Medium-Weight Headset / A5M Connector

Description

The PH-3 is a dual-sided binaural headset designed for professional audio and broadcast environments. It delivers stereo audio reproduction with medium weight and foam-filled cushions that provide a light wearing feel and moderate isolation from ambient noise. The headset is optimized for extended use in production control rooms, broadcast booths, and live event setups.

Key features include full foam cushions, a dynamic noise-canceling microphone, and a continuously adjustable ball-joint mic boom for precise positioning. The microphone offers background noise rejection to improve intelligibility in noisy environments. The headset retains a balanced feel while offering reliable isolation and comfort during long shifts.

Technical performance includes a speaker frequency response of 100 Hz – 10 kHz and a speaker sensitivity of 95 dB. The dynamic noise-canceling microphone covers 200 Hz – 6 kHz, has a listed sensitivity of -65, and a microphone impedance of 150. Channel impedance is 300 ohms per side and the supplied cord measures 1676.4 mm (5.5 ft) for flexible placement.

Connectivity is provided through A5 connector options, available in A5F or A5M configurations to match common intercom and partyline systems. The cable length and connector choices make the headset compatible with rack-mounted beltpacks and desktop intercom interfaces. No additional adapters are required for systems using RTS-compatible A5 connectors.

Typical applications include broadcast production, OB vans, live event comms, and studio talkback where clear voice communication and operator comfort are priorities. The headset is well suited for users who need a balanced combination of isolation and comfort without the bulk of heavier models. It supports workflows that require clear speech intelligibility and reliable in-ear monitoring.

Build quality focuses on functional durability and operator comfort – foam-filled cushions for extended wear, a medium-weight profile to reduce fatigue, and a robust ball-joint mic for repeatable positioning. The dynamic noise-canceling microphone maintains signal clarity in noisy environments and the cord length provides flexible station placement. Overall, the PH-3 balances comfort, clarity, and compatibility for professional AV and broadcast applications.
