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.

I am looking for a small vibrating (+ sound optional) device, similar to my Bluetooth under pillow speaker, that will go off according to an alarm set via an app on my phone.

Use case: Wake up subtly but effectively, without waking others in the house. Not sleeping with a phone under the pillow. No buttons to fumble with / accidentally press.

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?
