NICEHCK NK1 MAX Type-C to 3.5mm DAC Adapter Cable CX31993 Chip MAX97220 Op-Amp: Check Your Phone's USB-C Audio Output First

This is a dongle-style USB DAC: the CX31993 decoding chip and MAX97220 op-amp sit inside the cable, turning a USB-C port into a 3.5mm headphone jack with its own amplification stage. The single compatibility check that decides everything is whether your device actually carries digital audio out of its USB-C port — most phones do, but some budget models output charging-only or analogue-only ports, and a few laptops mute the audio lines. If no sound appears on first plug-in, the cable is not at fault. It is a portable adapter, not a desktop amp: chip-based dongles of this class are meant for IEMs and sensitive portable headphones, and the page does not publish an output power figure, so do not expect it to drive high-impedance planar or 250-ohm-plus headphones to volume. Whether the 3.5mm ring supports microphone and call controls is not stated on the listing — if you need headset functions, confirm with the seller before ordering.
