When will an Apple brand hearing aid be available?

I'm in the market for a more advanced, modern, hearing aid. I'm curious when Apple will come to market with their own hearing aid product? Hearing aids are not just for senior citizens by the way, the stigma as such should no longer exist. We need cool designs, fun colours, and exciting functionality. They need to be light weight for sure, but they can stop trying to be camouflaged with ugly 'skin tone' colours...I mean, most people don't try to cover up the fact that they wear eye-glasses. Anyway, a huge un-tapped market exists across all age groups and Apple would have great success in this area if they would just get on with it already.
