Standard Fit Hi-Fi Earplugs Zildjian Standard Fit Hi-Fi Earplugs reduce noise and harmful sounds, protecting your hearing while still allowing you to hear essential conversations and sounds. They uniformly reduce sound volume (approximately 20 decibel reduction) without altering the sound or music itself. These earplugs protect your ears from loud noises, but you won't miss any sounds you need to play or important announcements, so you can still have a normal conversation while wearing them. The slim design fits snugly over the ear, making them comfortable to wear under hats, helmets, or other headgear. They're recommended for drummers, musicians, and anyone looking for earplugs that won't interfere with their performance, or who wants to protect their hearing from loud noises at music events. The carrying case can be attached to a keychain or backpack, and the neck cord makes it easy to insert and remove the earplugs, so you can always have your hearing protection close at hand.Accessories: Earplugs, carrying case, carrying hook, neck cord
