I've got the Apple USB-C headphone dongle. It just doesn't have enough power to drive the headphones I want to use. Which is a limiting factor with most of the available dongles. Not enough good sounding power. The Hidizs dongle has reasonable power but sounds more and more harsh the louder you play it. It really sounds like arse, and harshes my mellow.
iBasso now has a DC01 dongle (balanced and 113 mW @ 32 ohms which should be enough for me) and a DC02 dongle (single ended with wimpy power that I will certainly find inadequate). I need to investigate the iBasso dongles. They're about $75. Otherwise it looks like I may end up with something like the iFi xDSD at $400. This future without headphone jacks is inconvenient and will force me to spend more money. The good part is that once I find a suitable solution I'll be set for future phones, chromebooks, tablets, and laptops to have suitable and consistent headphone sound with all of those devices.
Meets like this are good opportunities to try things and get advice. Which is a big reason why I go to meets and bring gear. Meets are a place to both learn and share.
