Please be aware that a law was passed about 5 years ago allowing "over the counter" hearing aids. They are not allowed to be called hearing aids, but rather "hearing amplifiers".
I use a "RIC" device from Otofonix.

I use the "Elite" and Encore" units. Very EASY to learn how to us them.
Their customer service is superb. You may return them after 30 days for ANY reason.
I prefer using a unit that uses batteries because it takes 6 hours to re-charge them and if you forget to throw them on the charger you are screwed for work that morning, lol. And if you travel, it is one LESS charger to pack.

Otofonix has improved my quality of life. (I have no ties to Otofonix, lol)
