There may already be tcoils in them If not, have your audiologist or hearing aid dispenser call the manufacturer and ask if there is room enough to add this program. Only they would know , not your dispenser so insist on the call.
Not sure where you bought them or what type they are. It’s disgraceful that this basic, necessary program is not even mentioned. I had my new Audi call the manufacturer to make sure the tcoils were in the new aids I ordered before I paid for them.

Also, you have a trial period so take advantage of that.
