Jabra 200567-001 headphone amplifier

For two-prong telephones, choose the VXi Console Amplifier. As easy to set up as it is to use, the VXi Console Amplifier gives you just the features you need, like transmit (microphone) and receive (speaker) volume controls. Uniquely designed, our Console Amplifier's headset cord is offset (attached to the side of the amplifier, rather than in the middle), to reduce stress and minimize repairs. Three models are available, for compatibility with VXi, Plantronics and GN Netcom/Jabra headsets.
