I purchased these items to be used in a therapy room for the charity I work for (Cancer support) I was assured by the seller (through a live chat on their website) that the two would work together. Now we have them in situ they appear to both be Bluetooth receivers so won't connect to each other??? Is there anything I can do to get them to play nicely together before I give up and accept that a highstreet big name have screwed over a small local charity?
