I bought this adapter:
and it wasn't working with my HTC U11 Life (there was error message to connect supported HTC headphones). But I found this application Audio Router. When I set Audio Jack from Default to On my standard 3.5mm headphones are working fine and in the same time I can charge my phone. Maybe this will be useful for others. I think that it would work with simple USB-C to 3.5mm adapters without charging or for other than HTC phones witch wont work by default wit those adapters.
