Modern practices of isolated listening manifest of mobile creation of privatized sonic worlds speak to and of a history of audile techniques conforming to larger social narratives of societal segregation.

Moreover, within the widespread assimilation of privatized listening, emphasis on record production ‘fidelity’ has suffered as a result of the portability afforded by modern privatizing media experiences.
