Thanks! Note you can also buy this without bolcom tax, since this seller has their own website: https://www.mmobiel.com/nl/mmobiel-usb-c-naar-3.5mm-trrs-hoo... There's also one with a DAC with better specs https://www.mmobiel.com/nl/mmobiel-usb-c-naar-3.5mm-trrs-hoo... (whether that actually sounds better iff the original one is already fine, I doubt)

Another downside btw is that you can't charge your phone anymore at the same time. I bought a wireless charger to remedy that but the device gets super hot, thermal protection kicks in, and it starts to throttle the charging. Doesn't seem great for battery longevity. There's devices that combine power and headphone jack into USB-C, but there I couldn't find a single one where the reviews didn't say it broke after two weeks or unusable sound quality or so. I simply miss a separate headphone jack... but this will have to do. Thanks for looking up which one you've got :)
