Make your own ear impressions for custom hearing instruments with the EZ Impression Kit by E.A.R. Customized hearing protection units require the end user to have an ear impression made, but this can be difficult to do if you cannot find a provider or facility to make them for you. To meet this need, E.A.R. has created the EZ Impression Kit, which comes with user-friendly instructions and everything necessary to make accurate impressions, including an order form, prepaid mailing label and the box for sending your ear impressions to the lab. Once you have your ear impressions, they can be used to make a variety of custom hearing instruments, from hearing protection to noise/water plugs. MSRP $60.
