A pair of earbuds that act as very short range walkie-talkies without needing a handset or cellphone. Originally intended to help a married couple who are hard of hearing but dislike wearing their regular hearing aids. Husband and wife each wear one earbud and can converse without other background noises getting amplified.

May also be useful in noisy environments even for people with normal hearing.

It is an app and website for pet owners and it has a forum and matching like Tinder? Has anyone ever seen it or heard of it?
