Description
The PHS-3.5-150 is a single-sided, super lightweight headset designed for daylong comfort and clear communication in professional AV and broadcast environments. It features a noise-canceling electret microphone mounted on a semi-rigid, fully adjustable boom for precise positioning. The earphone uses a wide-band dynamic driver covered in leatherette for improved fit and isolation.
Key features include a noise-canceling electret microphone for clear voice pickup, a semi-rigid adjustable boom for repeatable mic placement, and a leatherette-covered dynamic earphone for consistent frequency response. The headset is optimized for a 150 Ohm impedance version to match legacy and pro intercom systems. The overall design balances low weight and durable materials to support long shifts.
Performance specifications include a headphone impedance rated at 150 Ohm +/-20% at 1 kHz and a frequency response of 200 Hz to 10 kHz for the earphone. Sensitivity is specified at 98 +/-4 dBSPL @ 1 kHz and 1 mW for the 150 Ohm model. The electret microphone offers a frequency response to 10 kHz and a sensitivity of -41 +/-3.5 dB re 1V/Pa @ 1 kHz, with an operating voltage of 2V through a 2.2K resistor.
Connectivity is provided via a 3.5mm 4-conductor connector for the PHS-3.5-150 model, enabling direct connection to compatible beltpacks and intercom interfaces that accept a 4-conductor TRRS-style plug. The single-sided design keeps one ear free for environmental awareness while delivering isolated audio on the covered ear. Cable length and connector format are set to standard professional values to ease integration.
Typical applications include broadcast talkback, live sound comms, production control rooms, and event staging where single-sided wear and noise rejection are required. The headset supports consistent voice intelligibility in noisy environments due to its noise-canceling microphone and isolating earcup. It is appropriate for users who require extended wearability and precise mic placement.
Installation and daily use are straightforward thanks to the adjustable boom, lightweight construction, and 6 ft cable. The leatherette earcup and stainless steel accents provide a balance of comfort and durability for regular professional use. The PHS-3.5-150 is engineered to fit into existing audio workflows with minimal setup and predictable mechanical adjustment.
