This Jabra GN in-line amplifier cable is lightweight and compact. It has an RJ11 plug one end and a Quick Disconnect plug on the other. It will work with any GN headset that terminates in a Quick Disconnect plug. It effectively increases the incoming volume heard through the headset and is especially suited to noisy office environments of for use by people who are hard of hearing. The cable has an easy to access volume control switch built into it, making adjustments quick and simple.
There are two GN in-line amplifier cables available. There is a standard version that will fit on a large range of current corded office telephones including the Centrex and Lucent systems and there is a version available that works specifically on the Toshiba Strata/DK telephone systems.
