I decided to test Surefire Earpro Sonic Defenders. They are inexpensive, compact and block loud harmful sounds. These earplugs are little different from regular ones, they have retention rings that lock the earplugs in place.

Hearing Protection is very important when shooting.

These earplugs block all sounds, so you cannot hear anything. Just like regular earmuffs.

Surefire Earpro Sonic Defenders are good but I prefer my MSA Sordin earmuffs.
