The Final Audio Design HEAVEN VI have taken some core concepts of HEAVEN IV earphone, tweaked them and applied them to balanced armature earphone. The HEAVEN VI have changed the housing from stainless steel to chrome copper and taken Balanced Air Movement (BAM) mechanism to a greater level of performance. The result is the first balanced armature earphone that perfectly reproduces the sound of a human voice. Using BAM, which optimizes airflow in the housing, this driver unit has been developed to our own specifications and has an aperture arranged on the back of the driver unit, which is usually sealed. Specifications: Housing: Machined chromium copper, Driver: Balanced armature, Sensitivity: 112dB, Impedance: 16 Ohms, Cord length: 1.2m. Accessories: Steel carry case, Silicon ear pieces (E type 5 sizes, A and B types 3 sizes each).
