Housing front is made of plastic (as with other devices of the Pioneer - 500 series).
There are at least 2 versions of the MJ-D 508. A model for the US market and other markets has an adjustable device voltage and a removable power cord (as in Tech nics devices). Here the display is dark yellow. In the devices sold in continental Europe, the display is white- light blue, large and legible and with good luminosity.
The remote control is clearer than the predecessor model Pioneer MJ-D 707 : Pioneer CU-MJ016. It can also be used on the MJ-D 707
