A USB-C to AUX cable is an audio adapter used to connect devices with a USB-C port (such as modern smartphones, tablets, or laptops) to audio equipment that uses a 3.5mm AUX input, like headphones, car stereos, or speakers.

USB-C (Universal Serial Bus Type-C): A reversible connector standard that supports data transfer, charging, and audio output in newer devices.

AUX (Auxiliary Port): A 3.5mm analog audio jack commonly found in headphones and audio systems for transmitting sound.

Digital-to-Analog Converter (DAC): A component often built into the cable that converts digital audio signals from the USB-C device into analog signals for AUX playback.

Compatibility: Some devices require active cables with built-in DACs, while others support passive audio output.

Audio Quality: Depends on the DAC quality and cable construction.

Use Case: Ideal for connecting USB-C-only devices to traditional wired audio systems without Bluetooth.
