FAQ Specifications Technical Details

TSC-i48

What is TSC-i48?

TSC-i48 is The Good Ear Company’s first BTE (Behind The Ear) hearing aid that enables individuals with mild to severe hearing loss to communicate more freely, function more easily day-to-day and achieve a whole host of other benefits, ranging from career advancement to better balance. It also has a feature called TSC (Threshold Sound Conditioning - hence the TSC name!) that is the underlying technology for some interesting improvements in the areas of hearing loss.
