The Plantronics Connection Lead allows connection of a headset to many headset telephones not requiring an amplified headset.
The Plantronics SB Lead has a Quick Disconnect plug at one end and an RJ11 plug at the other. The RJ11 plug is the same as the shape as the plug on either end of the curly cord that plugs into the handset of the telephone.
Only certain phones will take the Plantronics SB bottom Lead. Other phones will require different connection leads, some that look exactly the same. Please use our Plantronics Compatibility chart to see which lead your telephone requires. If you are unsure which bottom lead you need to order, don't hesitate to contact us.
