Actually works
Super surprised for the price! Totally in ear canal and invisible. And you can not hear it sitting next to the person. Obviously not the highest quality sound and you need to hide the wires under your clothes, but it lets you listen to your audiobooks/podcasts without something obviously blocking your ear. I hear well at just half volume. The button is a little silly. You might need to rig so it's permanently pressed or don't plug the 3.5mm jack all the way (90%).

The volume even at max is not loud enough with iPhone. I tried with other devices and it is slightly louder. I have to place the copper closer to my ear to make it louder which is not the design. Batteries are brand new as well but volume is too low. Maybe a fix for that?
