How do you connect to the PA system in your church? I love my BT options in many settings, but not in large rooms, sanctuaries, etc. The telecoil in the hearing aid works so well if the venue has a hearing loop installation. Unfortunately, so many hearing aid fitters don't bother to activate the telecoil in the hearing instrument. And, of course, some of the hearing instruments don't have telecoils. It helps to know about them so you can ask for this feature when purchasing hearing instruments. They do not add cost to the product. BT does.
