Anyone using decibullz earplugs?

Have any of you guys used the decibullz earplugs with the percussion filters for hunting? I was wondering how well they work and how well you can still hear ambient noises.

I bought some for duck and squirrel hunting this year. They form to your ear very well and never worried they would fall out.  Really pleased.  As far as hearing ambient noise or buddies talking in the blind it was difficult.  They def do there job blocking sounds.
