The body harness and headstrap had to be as light and unobtrusive as possible too - no mean feat when dogs come in different shapes and sizes, even within breeds.
The headstrap is near-identical and the same leather-look earcups and gold details have been used (including the gnarled housing on the 3.5mm jack) so that from a quick glance, they almost look the same.
The head pad is larger and can be moved to better fit your head, the strap can be adjusted at a number of points and the sliders beneath the 0.7-inch OLED monitors can be adjusted independently from one another.
