In order to ensure total protection and comfort, customised hearing protection is manufactured using a direct impression of your ear. This ensures that when your custom hearing protection for shooting and hunting is used for prolonged periods, pressure points are a thing of the past. Here, in detail, how Amplifon’s custom manufacturing process works: Make an appointment at your local Amplifon store to have the impression made.  During your appointment, having specified the use intended, the best product will then be evaluated. Following this, an impression of your ear will be made. Your custom hearing protection will be made for you. 10 days later, you can either pick up your custom moulded earplugs in store, or receive them by mail.
