With an object to provide easy-to-assemble headphones with a stable waterproof performance, a headphone is formed of a mechanical attaching mechanism mechanically putting a front housing 5 and a rear housing 3 together, a waterproof mesh portion 11 having a first waterproof mesh 9 of a shape larger than a shape of a sound releasing hole 5c of the front housing 5 and disposed on an inner surface side of the front housing 5 so as to cover the sound releasing hole 5c, a first elastic ring 13 allowed to abut on an inner surface of the front housing 5 and a peripheral portion of the first waterproof mesh 9 of the waterproof mesh portion 11, and an inner housing 51 pressed by the rear housing 3 when the front housing 5 and the rear housing 3 are put together and in turn pressing the waterproof mesh portion 11 toward the inner surface of the front housing 5.

A headset (1) comprising at least one earphone (2, 3) with at a first earphone side (39) and earphone attachment means (14) for detachably attaching an ear pad (8) with co-operating ear pad attachment means (16) to the first earphone side (39). The headset (1) further comprises a wearing device (4) for attaching the headset (1) to the head of a user, such that the first earphone side (39) faces the ear. The earphone attachment means comprise magnetic elements (14), such that an ear pad (8) with co-operating magnetic ear pad attachment means (15) can be magnetically attached to the earphone (2, 3). The invention also relates to such an ear pad (8).

A headphone cover assembly that fits onto any of a variety of pre-existing headphones to protect the wearer from contacting the headphone and providing a clean, dry and comfortable surface against which the user's ears rest.

A hearing aid maintenance system including a housing for receiving a hearing aid to be charged and dried and a hearing aid charging port, a fan, and a heater for heating air to assist in drying the hearing aid. The system includes circuitry for controlling the hearing aid charging port to selectively charge the hearing aid, for controlling the heater to maintain a battery charging temperature within a predetermined range, and for controlling the fan to provide a flow of air to dry the hearing aid.

The invention discloses a casing assembly and an electronic device. The casing assembly comprises a middle frame and a dustproof assembly, wherein the middle frame has an outer surface, the middle frame is used for setting a microphone and is internally provided with a tone guide channel, the tone guide channel comprises a first end and a second end opposite to the first end, the first end penetrates through the outer surface, the tone guide channel continuously extends from the outer surface to an inner portion of the middle frame, the second end is formed in the middle frame, the microphoneis opposite to the second end, and the dustproof assembly is arranged in the tone guide channel and is between the first end and the second end. The dustproof assembly is arranged in the continuously-extended tone guide channel, dusts can be isolated from the middle frame or the portion of the tone guide channel adjacent to the outer surface of the middle frame, and the dusts are prevented from entering the middle frame and causing damage to components to affect the use effect. As continuous extension of the tone guide channel, additionally setting a casing for fixing a dustproof net is not needed, and the middle frame is made to have the possibility of being exposed directly as a mounting part.
