Abstract: Provided is an ear-hook device, and the ear-hook device comprises an ear-hook part and a connecting part. The ear-hook part comprises a first wire and a second wire adjacent to the first wire. One end of the first wire is connected to one end of the second wire, and the other end of the first wire penetrates into the connecting part. Provided is also an ear-hook microphone, and the ear-hook microphone comprises the ear-hook device, a guide rod and a microphone. The guide rod is positioned between the ear-hook device and the microphone. The first wire and the second wire are positioned to respectively abut against the user's ear back and head, allowing the ear-hook device to be hung on the user's ear more stably and the pressure pressed on the user's ear to be distributed.
