I briefly mentioned that I have a "blue-tooth appliance" (without explanation what it does).
For aids that include a telecoil (magnetic transducer), there are much less expensive neck loops that plug into a headphone jack. For RF-based hearing impaired systems that I designed and specified for public spaces, I specified the Comtek NTC-102 neck loop. I see it listed at $95 from internet vendors. It has the obvious advantage of zero latency.
This is a relatively rugged professional product from a company based in Salt Lake City. It's something that could easily be built -- the only unknown is whether the loop is a single turn or multiple turns, and this could easily be learned by winding one and trying it.
