Good
Normal USB wired earphone works. But dongle DAC like KA13, KA15 , or DS1, DS2 will never work, because of high power demand by these DAC dongles.

*Limited compatibility with BASE iPhone models* This USB-C audio and charging splitter is not recognised as an audio device on BASE iPhone models; wired headphones are not detected and audio continues to play through the phone speaker. This is because the splitter does not contain an internal audio processor (DAC) and is recognised by BASE iPhone models as a power accessory only, so USB-C audio is not negotiated. The same splitter works correctly and seamlessly for audio on iPhone Pro / Pro Max models. The adaptor is solidly constructed and well finished. Buyers should check Apple BASE iPhone model compatibility before purchasing. Tested on: iPhone 15 (BASE model) and iPhone 15 Pro Max using Apple USB-C EarPods.

Fonctionne également pour brancher un micro tout en chargeant (dans mon cas, un Rode VideoMic ME-C). Un "must" quand on sait à quelle vitesse un GSM se vide quand on enregistre de la vidéo HDR :)
