Just noticed when you click on the link to update to 4.0 it on shows the 4.1 update . I already have the 4.0 update on my setup now but was looking at buying a used set of WS5 headphones from a fella and he was going to load 4.0 on them and he told me 4.0 was not available anymore is this true as I don't use the pin pointer and from what I see there is not much difference please educate me as I am old and senile LOL Thanks
