Pixel 2 USB Type C to Audio Adapter

Hey all, recently taken advantage of the Pixel 2 JB Hifi deal.

However it only comes with one Type C to Audio adaptor. Tried purchasing a few different ones on eBay but none works as they are "analogue" so a few dollars down the drain there.

Anyone with recommendations to get ones which will work with the Pixel 2?

Specifically after one which is straight Type C to 3.5mm and one which is Type C to 3.5mm + Type C (so you can charge and listen at same time)

Thank you in advance
