I had a similar experience with my Amvox 2 and I found that loosening the strap a notch helped reduce the pressure of the case back. That may or may not be of any use to you!
If you can’t get the Amvox 2 to be comfortable on your wrist then I agree that it is a no go.
I believe the case of the Amvox 7 was re-designed in some way and I wonder if that has helped address the sharp edge on the case back? Can you find another friend with an Amvox 7 for you to try?!
All the best,
Jon
