I have decided to get some and was wondering if anyone had any experince with them.  I will mostly use them for gun hunting.  I want some that will amplify the sound since my hearing is pretty bad.
What features should I look for and compare when looking?
I see that Pro-Ears has 2 types.  The Dimension 1 and the Dimension 2.  The Dem 2s have a input jack which allows the plugging in of a radio.  My sons and I do keep in touch by FRS radios so that might be a good feature.  Is this needed?
Any help will be appreciated.
