## Long description

The PREMIUMCORD ku31zvuk04 USB-C to 3.5mm jack adapter with integrated DAC chip and charging function is a compact accessory that converts digital audio from USB-C devices into analog output for wired headphones or auxiliary inputs. With a 13 cm cable length it provides a short, flexible connection suitable for smartphones, tablets and laptops that no longer include a dedicated headphone jack. The built-in DAC chip performs digital-to-analog conversion inside the adapter, ensuring compatibility with devices that require an external audio converter.
Advantages
This adapter combines an external DAC chip and a simultaneous charging port in a compact form factor, allowing users to listen to audio through 3.5mm headphones while charging the host device. The short 13 cm cable reduces clutter and keeps the audio connection close to the device for convenient handling. The design focuses on plug-and-play operation without the need for additional drivers on most modern operating systems, and it supports a reliable wired audio connection where wireless options are not desired or available.

How to use
Connect the USB-C plug to the device’s USB-C port. Insert the 3.5mm headphone plug into the adapter’s audio jack. If charging is required, connect a USB-C charging cable to the host device or to the adapter’s charging input if present and supported; the adapter allows simultaneous charging while audio is in use. Most devices will recognize the adapter automatically and route audio through the connected headphones. Adjust the host device’s volume and audio settings as needed.
Usage recommendations
Use the adapter with compatible USB-C devices and standard 3.5mm headphones or auxiliary inputs. Avoid excessive bending of the short cable and do not expose the adapter to moisture or extreme temperatures. For best audio performance, use headphones with appropriate impedance for mobile devices and keep the host device’s firmware updated to ensure compatibility.
