I dont understand why would anyone wear this. It is less annoying regarding look than Apple earphones (that look like in-ear cigarette, I am still unable to get used to someone wearing them). I cant remember when it was last time I have seen someone wearing such a large piece of earrings - except maybe some old lady.
Is this just a prototype and you can make them smaller? Probably not as you need that part over the ear channel to hide the transparent tube, like with hearing aid, right?
