I love my Apple type-c dongle, and although it can only really be used with UAPP or something similar on my device due to the volume limitation when using it in conjunction with the phone's internal DAC (which essentially means no YouTube), the amount of value it packs into such a small package, from APPLE no less, is incredible. I bought an iBasso DC03 Pro recently for use with my Shure Aonic 4s, and whilst it does sound a bit deeper and the sound stage is wider, I wouldn't honestly consider it that necessary especially with cheaper IEMs.
