Miss D

It fit my phone straight out of the box and there is also a bag of alternative connectors/jacks/plugs if your phone's headset port isn't for a RJ9 jack/plug/male (the clear plug you squish into the female port at the back of your phone). This headset is better than the BT Accord 20 headset it replaces, and it is compatible with my BT Converse 2100 Corded landline phone as shown in pics. This port is the same size as the port for your handset jack that plugs into your phone, whereas the main port in to your phone to make your phone have a live connection is the same but larger and is an rj11 jack, look like small lego bricks with a little peg-like integral clip you squeeze to get it into the port/hole/socket.

Very happy with this and wish I'd have got it sooner instead of struggling with a poor quality headset for too long.
