This compact adapter transforms any USB or Type-C port into a high-fidelity 3.5mm headphone and microphone jack, delivering crystal-clear sound for gaming, streaming, and conference calls.

4. Frequently Asked Questions (FAQ)
Q1: Does this adapter work with a standard USB-A port? A: The primary connector is USB Type-C. However, if your device only has a USB-A port, you can easily use a Type-C to USB-A adapter (not included) to connect it.
Q2: My laptop has a combined headphone/mic jack. Why do I need this? A: If your laptop uses a single 4-pole jack (CTIA/OMTP standard), this adapter allows you to separate the signals into two distinct 3.5mm ports. This is perfect if you want to use a studio microphone and headphones separately, or if your built-in jack is producing static noise.
Q3: Will the 9mm spacing fit all headphone/mic plugs?
A: Yes. Standard 3.5mm plugs have a diameter of roughly 6.3mm. The 9mm spacing provides a 2.7mm gap between the two plugs, ensuring they do not touch or press against each other, which prevents short circuits and audio cutouts.
Q4: Is this compatible with Xbox or Nintendo Switch?
A: It is compatible with the Nintendo Switch (Docked or Handheld) and the PS5/PS4. However, it is generally not compatible with Xbox consoles due to their proprietary audio protocols.
Q5: Does it support high-impedance studio headphones?
A: This adapter is designed for standard consumer headphones (16-32 Ohms). For high-impedance professional studio headphones (over 150 Ohms), the volume might be lower than expected. It works best with headsets and earbuds.
Q6: Do I need to install a driver for Windows 11? A: No. It uses the standard USB Audio Class 1.0/2.0 driver native to Windows. It is truly plug-and-play; just insert it and wait 3 seconds for the system to recognize it.
