Now, I've tried *many* devices that do this, or claim to - none of them have really cut it. It helps, a little, but not really enough to make a difference.
These things? OH. MY. GAWD. I have 95% speech comprehension without even looking at the TV. I can hear esses. These work better than my hearing aids do, and something about that is just wrong! (in a good way)
Now, it's definitely the honeymoon period. I have yet to try these with anything other than the TV. We're going to try to catch a movie in the next couple of days, and I'll have to see if I can plug them into the phone. And, of course, these don't do a thing for face-to-face communication. But I am more excited about these than I have been about a hearing-aid gadget in a loooong time.
