It works great with the Pixel 5! I can absolutely recommend it.
The P20Pro outputs an analogue audio signal via USB-C, so the jack socket is purely an adapter. The Pixel 5 outputs a digital audio signal, which requires a driver like the Sharkoon DAC. This gives you a much better sound quality than with most of the smartphone's jack outputs.
