Abstract: A Bluetooth earphone and an ear-hook device thereof are provided. The Bluetooth earphone includes an earphone body and an ear-hook device. The ear-hook device includes a hinge assembly and an ear hook. The hinge assembly is rotatably disposed on the earphone body. The ear hook is rotatably disposed on the hinge assembly. As a result, the ear hook is able to rotate around the earphone body on two different axes via the hinge assembly, such that a user can selectively wear the Bluetooth earphone on his or her left ear or right ear.

Abstract: A personal audio listening device is adapted to be worn on a user's ear, and includes a housing, a pivotal knob, and an ear hook member. The housing has a surface and a hollow portion, and defines a first axis and a second axis. The pivotal knob is pivotally mounted on the surface of the housing, and includes a pair of parallel resilient walls. The ear hook member includes a hook body and an end portion. The end portion includes a pivot element in the form of a polygonal post. The hook body is configured to be wearable on the user's ear. The ear hook member is fittingly received between the resilient walls by means of the pivot element so as to be mounted on the pivotal knob. The ear hook member is pivotable about the first axis, and is rotatable about the second axis.

Abstract: A personal audio listening device is adapted to be worn on a user's ear. The personal audio listening device includes a housing, a coupling seat, and an ear hook member. The coupling seat is mounted on a surface of the housing, and includes a pivot portion. The coupling seat defines an axis passing through the center of the pivot portion. The ear hook member includes an ear hook portion and a hooking ring. The ear hook portion is substantially C-shaped, and is adapted to be worn on the user's ear. The ear hook portion has a first opening. The hooking ring extends integrally from one end of the ear hook portion to form a C-shape. The hooking ring has a second opening confronting the first opening. The ear hook member engages the pivot portion of the coupling seat through the hooking ring, and is rotatable about the axis.
