I have a question that has been bugging me a long time. If I use a old sennsenhour, model 840 , tv listening devise, wearing head phones. (w/o hearing aids on) , , I can understand most of the TV speech pretty good. If I us my octicon hearing aids with the octicon tv listener, (no model 840) speech is lousy. audiologist says my brain cant handle it???. I have has same results wearing other brand HAs. anyone have similar reaction? Is it old analog stuff is better than digital??? All the digital compression/tweeking etc , does it help or distort???
