The present invention provides an earcap and an earplug, the earcap has a shell made of a flexible material, the two ends of the shell are respectively provided with a sound inlet and a sound outlet, the interior of the shell is disposed in a through manner, a filter net is disposed at a position close to the sound outlet, in the shell. The earplug comprises an earcap and a filtering core mounted in the earcap, the earcap has a shell made of a flexible material, two ends of the shell are open, the two ends of the shell are respectively provided with a sound inlet and a sound outlet, the interior of the shell is disposed in a through manner, the filtering core is mounted between the sound inlet and the sound outlet, a filter net is disposed at a position close to the sound outlet, in the shell.

A wireless noise-cancelling earplug includes a housing within which at least an active noise cancellation (ANC) circuit for producing anti-noise, a speaker for emitting the anti-noise as a sound wave, and a battery for powering at least the ANC circuit. The earplug further includes an audio cavity for guiding the sound wave from the speaker out of the earplug, at least one microphone for measuring ambient noise and feeding the measured ambient noise to the ANC circuit, and a passive noise reduction unit for blocking ambient noise.

Various techniques are provided to implement and use an earpiece having an attachment mount. In one example, an earpiece includes an arcuate rib having a lobe disposed on an upper end thereof and configured to engage with a crus of a helix and an antihelix of a user's ear. The earpiece also includes a mount extending from the arcuate rib and comprising a snap clip configured to engage and position an audio device in contact with the user's ear. Other implementations and related methods are also provided.

According to an embodiment, a hearing aid is disclosed. The hearing aid includes a first functional unit and a second functional unit. The second functional unit is configured to removably couple with the first functional unit. The coupling provides at least a mechanical connection between the first functional unit and the second functional unit. The first functional unit includes a moveable element that is configured to move between a first position and a second position. In the first position, the moveable element is contained entirely within the first functional unit. In the second position, a part of the moveable element is configured to protrude out of the first functional unit. The second functional unit includes a recess configured to receive the part of the moveable element that protrudes out of the first functional unit such that the first functional unit and the second functional unit are immovably locked with respect to each other in response to the moveable element is received in the recess.

Headphone eartips with internal support components and methods for making the same are provided. Different support components may provide specific amounts and types of additional rigidity at specific portions of an exterior surface of an outer eartip body that may be expected to interface with specific portions of an ear canal geometry when an eartip subassembly is positioned within the ear canal, such that the eartip subassembly may conform to the various shapes of the ear canal while maintaining an acoustic seal.
