Telephone conversation isolation and enhancement systems for a caller using a telephone for a telephone call. The systems include a housing comprising an edge that circumferentially bounds an opening. The edge may contact a caller's head to create a substantially circumferentially continuous interface between the edge and the caller's head. The interface may enclose the caller's mouth such that speech sounds produced by the caller may emanate into the housing. The housing may attenuate transmission of the speech sounds to a call neighbor. The systems may include a first communication path configured to enable speech sounds produced by the caller to reach a telephone and a second communication path configured to enable transmission of audio signals from the telephone to at least one of the caller's ears. The second communication path may attenuate transmission of audio signals from the telephone to the call neighbor.
