⚠️ Important Notice: Dual 3.5mm Jacks & Microphone Wiring Requirements

1. Dual Dedicated Audio Jacks: This external sound card features two separate 3.5mm ports: one stereo audio/headphone output jack (green) and one dedicated microphone input jack (yellow). It is NOT a single 4-pole combo jack.
2. Microphone TRS Connector Required: The 3.5mm microphone input jack strictly requires a standard 3-pole (TRS) microphone connector. It does not support 4-pole (TRRS) single-plug headsets directly or 2-pole (TS) microphones. To use a single-plug gaming headset with a mic, a 3.5mm TRRS female to dual TRS male splitter cable (not included) is required.
3. Plug-and-Play Driverless Operation: Standard stereo audio playback, microphone recording, and hardware volume/mute buttons operate plug-and-play across modern operating systems. Virtual 7.1 channel simulation effects depend on host OS settings or audio simulation software.
4. USB-A Host Interface: Features a standard USB 2.0 Type-A male plug. Connecting to USB-C-only laptops requires a USB-A to USB-C adapter.

Frequently Asked Questions FAQ

Q: Can I plug a single-plug smartphone headset (with built-in mic) directly into this adapter?
A: Smartphone headsets typically use a single 4-pole (TRRS) plug. Because this adapter features separate 3.5mm headphone and microphone jacks, you will need a 3.5mm TRRS female to dual TRS male Y-splitter cable to use both the headphones and the microphone simultaneously.

Q: What do the red and green indicator lights mean?
A: The green LED indicates normal operation and audio playback activity, while the red LED illuminates when the microphone is muted using the physical mute button.

Q: Do I need to install any driver software to use this sound card?
A: No. It utilizes standard USB Audio Device Class drivers built into Windows and macOS. Simply plug it into an available USB-A port, and your system will detect it automatically.
