AdastraCompact Beltpack Induction Loop Receiver,Black,12cm

Would this be any good in a cinema? I'm autistic and noise from others distracts me easily. I wondered if this might be a solution.

Adastra lr2 is this ok for hearing aids on the t setings ? don

The description say it is for testing and setting induction loop. It isn't sufficient for hearing impaired ?

Can any advise me on the latency of this product, can i have a few using as inear monitors?
