This is bundled set (left and right side) of Dynamic Fuzz "Ear Fuzz" and "Fuzz Covers." The Ear Fuzz is applied directly to the clean exterior of your hearing protection and is designed to help reduced sound bleed-through due to harmonics, enable cable management, and allow mounting patches. The Fuzz Covers are intended to protect exposed fuzz, pin unused cables between it and the fuzz covers, and break up the pattern of the hearing protection.
