For its cost, a very good purchase, I am very satisfied. I have bought a more expensive one and it constantly whistles and causes headaches.

Quite powerful, good construction for the money I would say flawless the only thing I don't know is its durability over time

I got it for my grandmother! It's good but when her hand approaches her head from the side where she wears the earpiece, it makes a continuous beep beep beep very annoying for those in the same space. Especially for her who wears it. Otherwise, compared to another earpiece she had, she hears everything. To the point that even though we had the TV at volume 30, she puts it on 9 or 10 and the rest of us can't hear.
