These are silicone earplugs. Regular earplugs can be stressful, with issues like sound leakage and easily falling out, but these fit perfectly, provide excellent sound isolation, and are highly recommended! I myself have been using them repeatedly, so I'm offering them for sale. They're also good for those with hyperacusis and are very helpful when working with loud sounds. Great for travel, airplanes, trains, and days when you want to sleep soundly. You'll be hooked once you try them. ------------------- ✨ Washable and reusable. ✨ Recommended for daily use by those with hyperacusis or HSP! ✨ Water washable! ✨ White color, so they're discreet! ⚠️ It takes practice to mold them for complete soundproofing (try experimenting!). ⚠️ Be mindful of your surroundings due to the high sound isolation. HSP, developmental disabilities, sleep disorders, and waking up in the middle of the night.
