Envoy Medical's website has links to information about its newest hearing device the Esteem. They discuss the differences between normal hearing and Esteem hearing. The site is accompanied by short videos that discuss hearing. The site posted above has a video of an Esteem patient that discusses her experiences with other hearing devices and the Esteem.
This site could have a lot more scientific data. Even consumers need to be aware of the science of how hearing works and why or why not this device is going to work for them. However, the basic information about the device and how it works is presented well and is easy to understand how the device is going to work once it is implanted.
