*quick questions* my drop pandas just arrived but I realized some things: 1) They only charge with certain usb-c to usb-c wires. If I connect them to my Apple 20w charger using an apple usb-c cable, they do not charge. However, if i use the oculus usb-c cable they do charge. Is there a standard requirement for usb-c cables for the pandas? 2) I only can use the included usb-c cable to use straight to my desktop and it works fine (I do this because I want to use the internal DAC and THX amp). However, this does not work with other usb-c cables. Again, is there a standard requirement for usb-c cables for the pandas? What if the included usb-c cable is spoilt, what other usb-c cables are compatible with the drop pandas?

The Panda doesn't seem to support the USB-C PD spec for charging, it only works with dumb chargers and not ones designed for laptops that can negotiate higher voltages. Two is probably similar issue, the Panda seems to only work with USB 2.0 which means it works best with basic USB-C cables that only have conductors for USB 2.0. My guess is the sense resisters are messed up on the USB-C port like they were on the RaspberryPi 4's first revision which had similar issues at launch.
