Well, is the Google Pixel adapter a digital one, or is it just using the analog L+R+G contacts on the USB-C? Is it compatible with all USB-C smartphones? The thing is the KZ USB-C cable has a DAC inside the USB-C plug. And I suspect is a good one. High output, clarity, etc. I am even tented of ordering another and cutting the cable off some 10 cm of the plug, to adapt a female jack and getting myself a DIY cable. For double the price of the Pixel adaptor, you can also get a Hidizs Sonata. This is a great option. Great sound, great build and the possibility of flashing 3 different firmware profiles, including one that bypasses the system sounds (mainly phone calls and messaging sounds) to the telephone speakers, and allows for 192 KHz of bitperfect stream using compatible apps.
