Quick Summary
The SureFire EP4 Sonic Defenders Plus are reusable filtered earplugs in medium size and black. They use a triple-flanged design and include filter caps that change how the earplugs are used, so the exact setup matters when choosing this product.
The low-profile shape is intended to stay in place with other gear such as a mask, helmet, hat, or supplemental hearing muffs. If fit and coverage matter for your use, compare the medium size and the retained profile before choosing an offer.

- Profile: The low-profile shape matters if you plan to wear a mask, helmet, hat, or hearing muffs at the same time.
