Звукова карта USB AUX jack, 2*TRS (Mic + Ear) (3D Sound) RTL

B00443 is an external USB sound card for connecting audio devices to a computer. It provides two-channel 2.0 sound through a USB port.

Two 3.5 mm TRS jacks offer connections listed for headphones, a microphone and line input. Virtual 3D sound processing includes Virtual 5.1/7.1 Channel modes, giving you these options for audio playback.

The product page states that the card is recognized after connection in Windows, macOS and Linux without additional driver installation or settings changes. Its compact, flash-drive-like body needs no separate power cable, making it a small external option for headphones and a microphone or an alternative when the computer’s built-in sound hardware is unavailable.
