The Earplug Cable Tidy lets you securely wind up the cable and protects mobile device Earplugs. Once you've used it a few times it's quick and easy to keep your Earplugs safe and the cable wound away tidily. Quick and easy to use: Thread the end plug through one of the holes in the Earplug Cable Tidy (You will need to work out which hole best suits the length of your Earplug Cable to retain the cable securely), Pull the cable all the way through until the Earplugs are safely positioned (protected) inside the centre area of the Earplug Tidy 4.Push the end plug through the hole in the Earplug Tidy that provide just enough length to push it across the top of the Earplugs (securing them so they can't come out) and fully into the end plug securing hole. Note: Different sets of Earplugs have different length cables. Determine which hole suits your cable best to retain the Earplugs securely in the central area and fully insert the end plug into the securing hole. You will probably need to push the wound up cable down a fraction to push the end plug back into the central area. If you like this check out more of my Thingiverse listings!
