Overview

The TRkin USB Audio Adapter is an external sound card that converts a USB-A port into separate 3.5mm headphone and microphone jacks. It requires no driver installation and works out of the box with Windows, macOS, Linux, and PS4. Weighing only 14 grams and housed in an aluminum alloy shell, it's highly portable and ideal for extending audio ports from the back of a desktop PC or replacing a broken laptop audio jack.
This adapter supports only TRS (3-pole) plugs and claims virtual 5.1 surround sound output. Priced around 600 yen, it sits firmly in the entry-level segment of USB audio solutions.
