Plantronics (Poly), Jabra Headset Training Cables, Adapters, their Functions


For many companies its important to have an experienced employee able to guide and train new employees on procedures and customer support. In order to do this a company needs to utilize three main items. The first is a headset and the second is a training cable and the third is either a bottom cable or an amplifier.

There are three different companies that have training cables for use with corded headsets.


1) Jabra Y-Training Supervisor Cable with Mute Button:

This cable allows to plug in 2 Jabra corded headsets for training purposes, allowing to mute one of the microphones (trainee) and splitting to outgoing sound to 2 people at the same time, this cable is fully compatible with the Jabra link 860 Digital amplifier and with all the button cable from Jabra for desk phones.

2) Jabra Link 850 Training/Supervisory Cord with mute:

For people who have the Jabra Link 850 amplifier there is a training cable specifically designed to work with it and has its own jack on the side of the amplifier. This cable allows a second headset to be plugged into the Link 850 and has capability of being muted by changing the setting on the cable.


3) Jabra Link 265 USB y-training cable:

The last Jabra/GN Netcom training cable is designed specifically for soft phones and has a USB connector that plugs directly into the computer. This cable works specifically with corded quick disconnects such as these headsets. This training cable is unique in that it has a volume/mute button built directly into the cable in case the trainer needs to mute themselves or adjust the volume.

(Side note: There is no training cable on the market that allows two USB headsets to be connected to it for training purposes.)

By connecting this cable to the bottom of the training cord you can plug in corded headsets to the computer in case your company switches to soft phones in the future.

The switch will split the incoming sound into both wireless headset and allows to mute one or both microphones of the wireless headsets. This adapter is recommended for wireless headsets and is not EHS compatible, for the same reason even if your VoIP has the EHS capability you will need to get a mechanical lifter for remote answer.

All of the training cables mentioned above work with their corresponding manufacturers headsets and only those headsets. For example: Only Plantronics training cables work with Plantronics H-series headsets.
