A lot of the complaints I see in the comments center around weight of the headset & resolution. Regarding weight wouldn't it make more sense to have an overhead track installed where you live discrete, that takes the stress off the helmet?

This person seems to have it mostly correct except the wires still touch their back. It would make sense to me to have nothing touching you so you don't feel encumbered.
