This ear bud should form a complete seal, blocking out sound. This is critical to achieve the highest possible NRR rating and protect your hearing. Step 2: Compress the foam tip by rolling between your fingers until it becomes malleable. Step 3: Quickly insert the foam tips into the ear canal as deep as it is comfortable to wear. Step 4: Hold in place for 10 seconds to ensure plug expands and seals in the ear canal. Outside noises should be significantly reduced. If not, remove the plugs and perform step 2-4 again until a good seal is made.
