Adapters for use with sound devices and methods for making and using the same. An adapter may include an adapter body including a wall having a first surface and a second surface, and a projection extending from the wall. The adapter is generally configured to be attachable to a sound device such as an earbud or earphone. A sleeve configured to at least in part extend into the ear canal of a user during use may be attached to the projection. The adapter may additionally include one or more unobstructed orifices extending through the wall of the adapter between the first surface and the second surface. The one or more unobstructed orifices may allow leakage of acoustical energy from the adapter, thus modifying the level of sound energy at certain frequencies transmitted to the ear canal of a user.
