Poly Headset Cable Adapter

The Poly 78333-01 is a headset cable adapter designed for anyone who needs a reliable wired link between a compatible telephone and a professional headset. One end terminates in a 2.5 mm sub-mini phone plug, while the other end uses an RJ-9 modular connector. This simple interface lets you plug a standard headset into many Panasonic KX-T series desk phones without extra hardware or configuration.

With a length of 19.5 inches, the cable gives just enough freedom to position your phone and headset comfortably, yet stays short enough to keep the work area tidy. The adapter follows the 8-pin EPS wiring scheme, which helps maintain clear audio from the first call of the day to the last. Because it is a direct wired connection, you avoid the dropouts or battery concerns that can occur with wireless solutions.

This adapter fits naturally in call centers, front desks, and home offices where Panasonic KX-T phones are common and steady voice quality is a must. Setup is straightforward: plug the RJ-9 side into the phone’s headset port, connect your headset to the 2.5 mm plug, and you are ready to handle calls hands-free. Whether you spend hours on customer support lines or need a simple way to free up your hands while talking, the Poly 78333-01 delivers dependable connectivity in a compact format.
