Telephone Amplifiers for Headsets

Telephone amplifiers work when your phone doesn't have a dedicated headset port, you simply remove the telephone handset curly cord and plug that into the amplifier, then plug the amplifier into the socket where the handset just came from.  Amplifiers have an extra port for the headset and a switch which will allow you to chose between headset or handset capability.

Amplifiers also allow you to control the volume of incoming calls much more accurately than you can with your phone on it's own.
