Frequently asked questions about the Unitron Insera S NW O
How much does the Unitron Insera S NW O cost? +
There is no single price for the Unitron Insera S NW O. It is fitted and sold by licensed providers who set their own fees, so the same model can differ by thousands of dollars between two clinics in one city, and the technology level moves it further still. What you are quoted usually bundles the devices with fitting, programming, follow-up appointments and a trial period, and those bundles are not comparable line for line between clinics. Ask each provider what the quote includes before comparing two of them, and see our guide to hearing aid costs for the market ranges by style and tier.
What technology levels is the Unitron Insera S NW O available in? +
The Unitron Insera S NW O is sold in 4 technology levels: Smile 9, Smile 7, Smile 5, Smile 3. The housing and the physical style are identical across them; what changes is how much the hearing aid does for you automatically in difficult listening, above all separating speech from background noise. That is where most of the price difference between two quotes for the same model comes from, so it is worth asking which level you are being offered rather than only which model.

Our guide to hearing aid styles covers which styles suit which degree of loss.
Is the Unitron Insera S NW O the current generation? +
