As previously mentioned, compilot ll or compilot Air for phone calls and media streaming, for tv a PhonakTV Link, all are available on eBay, just use the search button.
You’ll need to do this properly using iCube ll and Phonak target software, or pay for a audiology clinic to do it for you.
It’s been said that the compilot ll can be be straight out of the box if new, but I’ve never been able to do this myself, I’ve always had to add the compilot or air in target to get them to work correctly.
