Caporegime
I paid $129 for them, and the lack of wire between them was one of the selling points for me.
Unless you're careless and don't put them back in the case after using them why would they get lost?
People lose things ALL the time, from keys, phone, wallet, a pen, money, watches, ear rings, full-size headphones. These are like ear rings, one for each ear except there is no clips to make them stay in place, and women have jewellery boxes to put them back in but they still lose them.
You can easily be crossing a busy street, falls off, guy next to you steps on it. Or just as luck have it, falls off when you are getting on the train/elevator and goes through the gap.
I can picture you forever have both hands on your head now every time you are near a place where they can fall off and never be able to retrieve.
