The accessories, or its included cables, are hidden under a compartment in the upper center of the carrying case. Packaging includes a 1.2m USB-C to USB-C cable for wired audio and charging and a 1.2m USB-C to 3.5mm cable. Yes, it means no “real” analog signal is passing through, and the Px8’s built-in DAC is used even when using the USB-C to 3.5mm cable. It doesn’t sound as good when you use the 3.5mm headphone jack compared to USB-C to USB-C or via Bluetooth. Not to mention, the included cables are too short anyway. I recommend just using the headphones wirelessly via Bluetooth.
