Product and purpose

The SOEWIOU CD0857 is a 2-in-1 USB-C to 3.5mm audio adapter that adds a headphone jack while passing through up to 100W of Power Delivery charging. It suits anyone with a modern USB-C phone, tablet or laptop that lacks a dedicated audio port and wants to listen through wired headphones or speakers without losing the ability to charge.

Thermals noise and power draw

The adapter draws power only for its built-in DAC and control circuitry, so it adds negligible heat or noise to the host device. Normal use sees the pass-through charging operate at the negotiated PD rate, up to 100W, with backward compatibility to 60W depending on the connected charger and device.

Sustained load behaviour

During extended sessions the smart chipset maintains stable Hi-Fi audio decoding and volume or call controls without driver intervention. The slim 5.12 in cable and 0.01 kg weight keep physical strain on the host port low, while the DAC continues to deliver digital audio free of current noise throughout the charging cycle.

Questions about this item

How do I install the CD0857 adapter and what step do people often miss?

Plug the USB-C end into your device and the 3.5mm plug into your headphones; the step people miss is using a PD charger rated for 100W to enable fast charging while listening.

What maintenance or replacement will the CD0857 need later?

No scheduled maintenance is required; replace the adapter only if the USB-C connector or 3.5mm jack becomes physically damaged or the cable frays near the 5.12 in length.

What limit appears first during sustained use of the CD0857?

The 100W PD charging ceiling is the first limit; actual output depends on your host device and charger, so sustained high-power charging may throttle below 100W.
