Various implementations include sleep aiding in-ear audio devices. Certain implementations include sleep aiding in-ear audio devices with a noise-reduction finish, along with methods of applying a noise reduction finish to an in-ear audio device. In some cases, a sleep aiding in-ear audio device includes: a set of earbuds, each earbud having: an eartip for mating with an ear of a user; and a housing coupled with the eartip, the housing containing an electro-acoustic transducer for providing an audio output to the user via the eartip, where when inserted in the ear of the user, substantially all of an exposed surface of the earbud is finished with a matte coating.

The disclosure is related to materials that includes phase change materials. The materials are suitable for use in acoustical devices such as headphones.

Acoustaical devices employing phase change materials

The disclosure is related to compositions having an elastomer and phase change materials, materials having an ability to provide one or more sensations upon contact with a person's skin, or a combination thereof. The compositions are suitable for use in earpieces such as in-ear earpieces.

Earpiece employing cooling and sensation inducing materials

A composition that can be used for abrasive processing is disclosed. The composition includes an organic bond material, an abrasive material dispersed in the organic bond material, and a plurality of microfibers uniformly dispersed in the organic bond material. The microfibers are individual filaments having an average length of less than about 1000 &#x3bc;m. Abrasive articles made with the composition exhibit improved strength and impact resistance relative to non-reinforced abrasive tools, and improved wheel wear rate and G-ratio relative to conventional reinforced tools. Active fillers that interact with microfibers may be used to further abrasive process benefits.

Microfiber reinforcement for abrasive tools

An abrasive article includes a body having an abrasive portion. The abrasive portion includes a bond material and abrasive particles located within the bond material. The body also comprises a coating coupled to and overlying at least a portion of an exterior surface of the abrasive portion. The coating has a water vapor transmission rate of not greater than about 2 g/m-day.

Abrasive article and coating

Bonded abrasive articles and in particular organic bonded depressed center wheels with one or more reinforcements have reduced stiffness in comparison to conventional counterparts. Techniques for producing and using such wheels are described. In one example, a method for reducing the stiffness of an organically bonded abrasive wheel includes applying to a raised hub region of a reinforced depressed center wheel a force effective to irreversibly decrease the stiffness of said wheel.
