Overview
The Eartec RJ9/4P4C QD Headset Bottom Cable (U10P) (EAR-QD002P) is a direct-connect cable for connecting Eartec headsets to compatible landline phones. One end features a Quick Disconnect (QD) connector, allowing users to easily unplug their headset and walk away from their desk without removing the headset. The other end terminates in an RJ9/4P4C (4-pin, 4-conductor) modular plug, designed to fit a phone's dedicated headset port. The cable is coiled, providing a flexible, tangle-free length that stretches up to approximately 80 inches. It is specifically wired for compatibility with certain phone models from brands like Polycom, Mitel, Nortel, and Aastra, but it will not work with mobile phones or computers. This accessory is an alternative to the Plantronics U10P cable (part number 27190-01) and is essential for office and call center environments using compatible equipment.
