Using these ear plugs is easy. First, choose the right size tip (standard M or large L) that fits your ear comfortably. Roll the silicone tip between your fingers to compress it, then insert it into your ear canal. Let it expand and seal to start getting the 20dB noise reduction. When you're done using them, don't just throw them around. Use the pick - shaped keychain case to store them safely. Also, keep them away from sharp objects to avoid damaging the silicone tips. To clean, you can gently wash them with mild soap and water, then let them dry completely before using again. Remember, these are for protecting your ears, so always use them when you're in a noisy musical environment.
