After finding an active cable module within the Acer headset, we were curious as to why the HP headset had no chips on their cable. So we opened up the proprietary connector on the cable (Do not do this. You won't be able to easily put it back together)

Under the plastic shell, we found a similar Spectra7 cable module similar to that of the Acer Windows HMD
