The RTS Telex PH-88 is a single-sided, lightweight intercom headset engineered to deliver exceptional comfort and reliable communication for broadcast, live event production, theatre, and professional audio applications. As part of Telex's renowned lineup of communication headsets, the PH-88 is built on a reputation of durability and field-tested reliability, making it a staple in control rooms, sports broadcasting booths, and stage management positions worldwide. The super lightweight construction ensures minimal operator fatigue during extended shifts, while the moleskin-covered wideband dynamic earphone provides a comfortable, secure fit with effective passive isolation against ambient noise.

The headset features a dynamic noise-canceling gooseneck microphone mounted on a semi-rigid, fully adjustable boom. This design allows users to position the microphone precisely for optimal voice pickup while the cardioid polar pattern and noise-canceling technology actively reject off-axis background noise. This ensures that communication remains clear and intelligible even in high-noise environments typical of live event production. A padded, adjustable headband further enhances the secure and comfortable fit for a variety of head sizes.

Engineered for seamless integration into professional intercom networks, the PH-88 is available with a variety of connector options including 4-pin XLR (A4F) and 5-pin XLR (A5M) configurations to match standard RTS intercom belt packs. The dynamic earphone delivers a speaker sensitivity of 109 dB SPL/mW and an impedance of 300 ohms. Customers may select either a straight (PH-88) 1.8m cable or a coiled (PH-88E) cable for added flexibility in mobile applications. The microphone features a sensitivity of -65 dBV/Pa and an impedance of 200 ohms, ensuring consistent performance with standard intercom systems.
