Thanks MrDrDr, that's a pretty edgy design! Our first attempt was an Octopus, holding on to the ear with its tentacles! But here's the problem with the spider web design: if you put a circuit board + battery front and center, sticking forward, it looks like a gigantic tumor on the ear. There's no way to avoid that. Which is why we focused on designs that hid the board behind the earring. We also wanted the earrings to be swappable (because I don't see most women wanting to wear the same look every day.) Our challenges were: hiding the circuit board, positioning the speaker near the canal, and allowing swappable looks. We spent months just figuring out how to solve these design issues.
