RJ9 4P4C Male to 3.5mm Female Headset Adapter Cable, 3.5 Jack to RJ9 Cord Compatible with Avaya Desk Phones

This conversion cable features an RJ9 4P4C male plug and a 3.5mm female audio jack, which allows you to connect your standard 3.5mm headsets to Avaya and other mainstream RJ9 interface desk phones. It solves the trouble of purchasing dedicated expensive office telephone headsets separately.

High-quality internal copper conductive wires and shielding structure effectively reduce external audio interference, ensuring smooth two-way voice communication during business calls with no noise or volume drop. The flexible thin wire avoids messy desktop wiring and takes up little space.

No complicated installation or configuration required. Just plug the RJ9 end into your desk phone headset port, then insert your 3.5mm headset into the female jack to start hands-free calls directly. It is an economical essential audio conversion accessory for office customer service, reception and daily business telephone communication.
