Looking For Suggestions

I'm in need of some help, and figured if anyone might have some suggestions, it would be our community.

At my work, we have a system set up where there's a microphone on the outside of some plexiglass.  This also acts as a speaker for our clients.  It feeds into a box with a microphone attached and also has a speaker on it so we can hear the clients.  The port is a headphone jack that is labelled outer.  This allows the audio to go from the outside to in, but the audio is garbage.

I'm looking for a female headphone to male headphone adapter that also supports bluetooth/has female USB C aswell, so we could utilize our bluetooth headsets at work, but also connect the system up still.  If you have a suggestion, please post a link.  (I'm also hearing impaired, so this would let me transmit directly to my hearing aid/cochlear implant)

I just put what you were asking for into Google, and the following popped up from Amazon. Hope this helps.
