The equip 147944 RJ9 to 3.5 mm Headset Audio Adapter connects a PC headset to a compatible VoIP phone headset port. Its two 3.5 mm sockets accommodate the separate audio and microphone plugs found on many PC headsets, while the RJ9 plug connects to the phone.
The cable has one male RJ9 connector and two female 3.5 mm connectors. It is intended for phones with RJ9, RJ10 or RJ22 headset jacks; RJ11 connections are not supported. Its 25 cm cable and plug-and-play setup provide a straightforward way to link the two connector types without adding a separate audio interface.
