Abstract: 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.
