About the item: [Making Music Sound Pleasant].BUENSUENO hi-fi earplugs are high-fidelity, noise-reducing earplugs that make sure you still hear everything, just a little less loud. They have a noise reduction rating (NRR) of 21 decibels. [Profectional Musician Earplugs]. The exclusive vacuum filter layer reduces treble and bass evenly, making music sound pleasant instead of Harsh and Sharp Noises. [Comfortable and Durable, Not Easy to Fall off]. These earplugs are easy to insert and when you wear them correctly, they don't stick out of your ears. They come in 4 sizes (XS - L), if your ears hurt, it is best to take a smaller size. If the earplugs do not reduce sound sufficiently or fall out, it is best to try on a size larger. [Four Sizes are Available, Reusable]. Our musician earplugs equip you with 4 sizes of ear tips, XS S M or L, that can be replaced and reused at any time, designed for Concerts, Festival, DJs, Drummers, musicians. [What You Get]. In the box, there is 2 sets of earplugs, 4 sizes of soft silicone ear tips (XS-L) and 1 handy carry case. The connection of the ear cap is firmly designed to prevent falling off. Please install it carefully when replacing it. After cleaning with water, the earplugs need to be dried. Since the high-fidelity earplugs have sound channels, if they are not dried, the liquid residue will cause noise.
