WE currently have plantronics C054 headsets and wondering if there is a compatible headset splitter setup that would allow for training where a second person can listen in on call

Hi @jkuder70, Welcome to the Poly HP Support Community.
I completely understand your need to connect two headsets so that a second person can listen in on a call at the same time—this is a common requirement, especially for training scenarios.
The Y-cable solution you're referring to is specifically compatible with the Poly EncorePro headset series, which uses QD (Quick Disconnect) connectors. One such option is the Poly Y-Training Cable, part number 27019-03. You can search online for this part number directly to view and purchase the cable.
However, for your current headset model, the Poly C054/CS540, the setup works a bit differently. These headsets are not compatible with Y-cables, but the base unit supports conferencing. You can connect up to three additional headsets to a single base for conferencing purposes.
For detailed steps on how to set up headset conferencing, please refer to the official user guide
