I exchanged the SmartR for the SmartU. I couldn’t understand how to control the SmartR settings. The SmartU took some work to set up but I was able to figure it out.
What I like about the SmartU is I am able to control the tone, bass, mids, and high. I have another set of hearing aids that doesn’t allow this, it is a nice feature.
I also like the fit, I have small ear canals. I like that I don’t have something hooked around my ear, even though that type is light in weight, after four or five hours it was uncomfortable with my glasses.
