Notification--Lost Streaming Item

I wear Bose Hearphones which can connect with 2 devices at a time (and switch with a 3rd). A voice tells me when I am, and am not, connected. If I walk away and–for example–leave my iPad on the grass, it says in my ear “iPad lost”. At least once this kept me from losing it!!! I don’t believe hearing aids give this information, and I think they should!
