I work w/ a kid on social skill and want to give real-time feedback. I want kid to have only an earbud, not to carry a device w/ him. I want to hear what’s around him, and for him to hear me only when I unmute and speak. I can use my phone, but kid’s parents don’t want him to have a phone or data plan. I have 2pairs of bluetooth earbuds to use, or his parents are willing to purchase something
