There was a time when I sold tons of these at the local swap meet (as a "NEW" retail electronics store), along with a local store-front. I recently found this is some boxes from that old business, I assume it to be working, but need to note that it's at least 8 to 10 years old in technology, so I am hoping you have a really old phone OR that you newer phone can talk to a really old version of Bluetooth, lol.
