I'm getting good results with MDHearingaid.com Air[0] over the past eight years. They work in reasonable environments, like the home, but aren't enough in a noisy, crowded room. Right now, they are $300 a pair, which is reasonable. Buy your mom a present for mother's day!
I had a Bose Hearphone, but it broke. It worked quite well - I think about as well as the high priced aids. Sadly, Bose discontinued it (why??) and I can't replace it. With four mics, it was able to cancel sounds from behind you. You only really heard the person you were facing.
Edit: I notice their dual-microphone Volts are selling for $300 a pair, also. I haven't tried them - but dual mic is what you need in noisy environments. Might be a really good deal.
