The Telex PH-88 is a professional single-ear headset engineered for critical intercom communication in broadcast, live production, and other demanding operational environments. Its defining characteristic is its super-lightweight construction, which prioritizes daylong comfort for users who must wear headsets continuously during lengthy productions or events. The headset features a single-sided, dynamic earpiece covered in soft moleskin for a comfortable, secure fit and improved acoustic isolation, allowing the wearer to hear clear audio while remaining aware of their physical surroundings.

For capturing clear speech in noisy environments, the PH-88 is equipped with a dynamic, noise-canceling microphone mounted on a semi-rigid, fully adjustable gooseneck boom. This design allows for precise positioning of the microphone capsule near the user's mouth, optimizing voice pickup while minimizing background sounds. The flexibility of the boom and the wide selection of connector options make the headset adaptable to various professional setups, from fixed studio installations to portable field kits.

The headset's technical design emphasizes compatibility and performance within professional wired intercom systems. It is built with a 6-foot cable and offers multiple connector options to interface directly with standard industry systems, including RTS, Clear-Com, and others that use common 4-pin XLR or similar terminations. The headset’s electrical specifications, such as its 300-ohm impedance and high sensitivity, are tailored to work seamlessly with professional intercom beltpacks and main stations, delivering clear two-way communication.
