First of all - Product behaves poorly - sound is extremely quiet, or very loud in one ear, due to dodgy connection with jack in socket.
Coloured bands on tip of jack plug are green and not the expected blue.
Airplane adapter plug is extremely shiny plastic..
No blue colour around volume control switches on cable (all black instead).
Additional mould line around hinges.
Supplied with no box packaging or manual, just a plastic bag surrounding the case which has differently stitched hanging loop.
