RJ9 Male to Dual 3.5mm Female Headset Adapter for Desk Phones

This RJ9 to dual 3.5mm female headset adapter allows you to connect a standard PC headset (separate headphone and microphone plugs) to desk phones that use an RJ9 headset port. It is ideal for office, call centre, and VoIP environments where you need to use a familiar PC headset with professional desk phones.

The adapter converts a single RJ9 headset socket into two standard 3.5mm jacks, one for audio output and one for microphone input, enabling clear communication without replacing your existing headset.
