If you are looking to preserve your hearing, you want to avoid exposure to loud noises for a long time. Aside from turning the music down, you can use accessories like ear plugs Singapore or muss which block loud sound and keep your inner ear protected.
Traditional earplugs are rather bulky and can draw attention to you. If you don’t want this option, think about using silicon or tapered earplugs. These devices can seamlessly fit into your ear without making people notice you have them on. These are affordable disposable products that can be custom designed.
