In fact, the only complaint I have is that the earbud was somewhat painful to begin with in my right ear

And my ear is sore after 8hrs of wear

don't stay in ear good.

The clear ear clip doesn't clamp very tightly on

I use my earpiece devices for hands-free calling/talking while driving, as well as when I need to make phone calls at home as it allows me to continue working (typing on the computer).
