Purpose and Audience

This CableDeconn A0403-gold adapter adds a 3.5 mm microphone and headphone jack to any device with a USB-C or Thunderbolt 3 port. It solves the problem of laptops or phones that have only one audio port or a damaged internal sound card. The 15 cm cable keeps the dongle close to the device without straining the port. Plug-and-play operation means no driver installation is required on supported systems.

Thermals Noise and Power

The unit draws power directly from the USB-C bus and uses an advanced C-Media IC for audio processing. No external power supply is needed and the compact ABS housing stays cool during normal use. Because there are no moving parts the adapter adds no audible noise to the signal chain. The short 15 cm cable minimises voltage drop and electromagnetic interference.

Upgrade Context

This adapter replaces a broken 3.5 mm combo jack or a failed USB audio dongle on Windows 10, 8.1, 8, 7, Vista, XP, Mac OS X, Linux, Chrome OS, PS4, Surface Pro 3 and Raspberry Pi. It is not for users who need 5.1 surround output over analogue connectors or who require a longer cable run than 15 cm. The jump is worth it when the original port is physically damaged or missing entirely.

Questions about this item

How do I install the USB-C 5.1 sound card and which step is commonly missed?

Plug the USB Type-C connector into a USB 3.1 or Thunderbolt 3 port, then connect headphones and microphone to the two 3.5 mm jacks; the step often missed is ensuring the host port supports audio class, otherwise no sound appears.

What maintenance or replacement will the adapter need later?

No routine maintenance is required; if the 15 cm cable frays or the USB Type-C plug wears out, replace the entire adapter as no user-serviceable parts exist inside.

What limit appears first during sustained use of the sound card?

The 15 cm cable length restricts placement flexibility before any thermal or bandwidth limit is reached under continuous audio streaming.
