Yes, I am very much for a hearing aid designed as fashion/jewelry item.
The difficulty is testing the market because you are much more likely to get false positives since there is a large gap between product affinity and buying behavior.
Customers may individually respond positively to a product but a lot more factors determine whether they will actually adopt the product.
In the fashion world, shopping simulations need to be set up to accurately test responses without bias.
I have followed several projects including one of our students’:
The most important thing is that with stigmatizing medical products, people don’t want to show it as having a medical function.
So, you need to design it like something anonymous or a different product (ear jewelry or earphones for example)
Then there is the workflow towards manufacturing but that aspect has opened up since over 90% of hearing aid devices worldwide are now 3D printed.
Let us hear from you throughout the project!
