Are the people at your audiology clinic sharing information with you about assistive technology that goes with your expensive hearing aids? Telecoils do amazing things. BlueTooth does too, but they are different. Hearing aids should have both options, and the providers should demonstrate them for you so you know what they do, and how to use them. Far too often the providers don't talk about these 'extras'. I learned about these options from other people who use them. I'm fortunate to have met people through HLAA (The Hearing Loss Assn. of America) way back in the mid-80s. We all learned together as technology evolved and became available. I use my telecoils on the phone, on my computer, with audio devices, and in public venues that have installed hearing loops. The BT devices work well in many instances, but don't do much in those public venues.Living well with hearing loss is truly a lifelong learning adventure!
