Physiotherapist Supervised】 Earplugs with Reduced Sound Burden for Auditory Hypersensitivity, Misophonia, Noise Canceling Earplugs I'm selling these because I bought them for my child, but they weren't used. The box, case, and replacement ear tips are not included, only what's in the photos. As you can see in the photos, the ruler shows the size of the hole, so other size ear tips should fit. Please read my profile. The following is a copy-paste from Amazon: Lightweight and barely noticeable: These earplugs offer a new sensation of wearing, feeling as light as air. You can use them in your daily life without stress. Aiming for stress-free: New filter-type earplugs that reduce unwanted sounds while allowing necessary sounds to pass through. Comfortable to wear: Designed for ease of use, balancing comfortable sound adjustment and fit. Lightweight and easy to carry: The lightweight and compact size makes them easy to carry around when you're on the go. Active in various situations: They are useful for improving concentration at work, noise reduction during travel, and ensuring quietness during sleep, and more. [Note] This product is the only sound-reducing earplug that allows you to hear sounds. It is not suitable for those seeking complete soundproofing or noise cancellation. Also, the effect may vary depending on the individual. Sensory hypersensitivity, HSP, work, study, commuting, school
