Review (1/5): and found I can hear better without it
I purchased wonder ear, and found I can hear better without it. Everything I hear with it sounds harmonic, kind of like there are two people talking at the same time. Same with music, sounds harmonic. I like the idea that it plugs in, but not the idea that I can't hear properly with it. I have a pair or another brand, that is also inexpensive, that run on batteries. And they are also not very good, as they let in mostly background noise, more than voices, as does the wonder ear. It's a waist of your money😩
