Which one is the Deluxe Audio Strap and which one is the Standard Audio Strap

There are 2 styles in this link. One has black headphones with the pie symbol and the other has black and silver headphones with the name Pimax. Which one is which? Which one Does Not project the audio like the Index? Are either one over the ear . It looks like the black one is above the ear. Is the black and silver over the ear or does it set off the ear. This is so damn confusing, nothing in the link explaining anything, just 2 random pics that dont coincide with the text, typical amateur Pimax website designing I guess
