I have also recently added sporttacs to my stable of electronic ear defenders and have been very happy, much better fit than any of the others I have and far better sound control, with instant on/off when shots fired.
I too have the Howard Leight Impact Sport. They don't cost the earth. Batteries are easy to change and last a good length of time. The last set lasted a whole summer of clay competitions, several range days and zeroing sessions, plus a whole season of game shooting days. I find them comfy, (admittedly I always wear them over a baseball cap or a flat cap,) esy enough to use, and are slim enough not to foul the stock either on a shotgun or a rifle.
Plumped for the Peltor Sporttacs too.
The in ear ones I would have to have custom made. Would loose at least one within a week and, just yuck.... On the few occasions that I've used the foam earplugs, they go straight in the bin!
(Though I did once put a few in some primed 38 cases and we shot them. Not sure I liked THAT bullet lube.)
