The shift from 3.5mm headphone jacks to USB-C ports on smartphones has led to questions about audio quality. While 3.5mm jacks output an analog signal directly from the phone's internal DAC and amplifier, USB-C typically transmits a digital signal that is converted by a DAC in the headphones or adapter. Although USB-C has the potential for higher quality audio with premium external DACs, the actual sound experience depends heavily on the quality of the components used, whether internal or external. For most users with standard equipment, the difference in audio quality is often negligible, though USB-C offers greater potential with high-end accessories. AI
