I wear in-ear and muffs when shooting the 50s or big magnums with breaks or SBRs with breaks. Otherwise just muffs. It's the in-ear customs I've never found a set that works for me. Old school roll up foamies are great but I don't like the time it takes for them to expand and have full protection when going from ears to no ears back and forth often.Double up, foamies + electronic + gel cups
