Abstract: An earphone including a housing, a bracket, a first speaker unit and a second speaker unit is provided. The bracket disposed inside the housing includes a front plate, a first tube portion, a second tube portion and at least one connecting portion. The first tube portion is connected to the front plate. The second tube portion is separated from the first tube portion. The first tube portion is between the front plate and the second tube portion. The connecting portion connects the first tube portion and the second tube portion. The front plate has a central hole and surrounding holes. The second accommodating space is communicated to a main audio-output path of the housing through the surrounding holes. The first speaker unit is disposed in a first accommodating space of the first tube portion. The second speaker unit is disposed in a second accommodating space of the second tube portion.

Abstract: A headphone including two earphone cups, a main strap and a decorating strap is provided. Two ends of the main strap are connected to the earphone cups. Two ends of the decorating strap are detachably connected to the earphone cups or the main strap and rotatable corresponding to the earphone cups or the main strap.

Abstract: An earphone including an earphone body, a photosensitive switch, a power supplier and a light emitter is provided. The photosensitive switch, the power supplier and the light emitter are disposed on the earphone body.
