This conversion cable features a 3.5mm female TRRS audio jack and a 4P4C RJ9 male plug, designed to connect regular 3.5mm headsets to office landline telephones with RJ9 headset ports. It works perfectly for call center agents, office staff and home landline users who want to replace original phone headsets with their own 3.5mm earphones.
High-purity shielded internal wires effectively block electromagnetic interference, eliminating buzzing and distorted voice sound during inbound and outbound calls. Gold-plated anti-oxidation contacts maintain stable signal transmission after long-term frequent plugging. The flexible PVC cord with reinforced strain relief prevents wire cracking at the plug joint under daily bending and movement.
No extra drivers or power supply required, just plug in to start voice calls instantly. Widely applicable to mainstream RJ9 desk phones, call center telephone systems and home landline devices, a practical audio conversion cable for daily office communication.
