USB 7.1 Sound Card for Gaming Headsets

The C&N USB Sound Card adds virtual 7.1 surround sound to any headset with a 3.5 mm connection. It plugs into a free USB port on a PC, Mac, PS4 or PS5 and works without installing drivers. The device is aimed at gamers who want positional audio and quick-access controls without opening their computer.

Virtual Surround Limited to Stereo Headsets

The adapter creates a 7.1 effect through digital signal processing on a standard two-channel headset. It cannot deliver discrete multi-channel output to speakers or headsets that require separate analogue channels. The 24 bit DSP raises output volume by 15 percent, but the final loudness still depends on the connected headset's sensitivity.

Inline Controls and Dual 3.5 mm Jacks

A built-in roller adjusts volume, while dedicated buttons mute the microphone, toggle 7.1 mode and trigger PUBG and League of Legends sound presets. The unit provides both a single 4-pin 3.5 mm headset jack and separate 3-pin headphone and microphone jacks for broader compatibility. No external power supply is needed.

Questions about this item

Which version of the C&N USB sound card should I choose if I need both a headphone jack and a separate microphone input?

This model provides a 3.5mm 4-pin jack plus a 3.5mm double jack that splits into a dedicated headphone output and microphone input, so a single unit covers both needs.

What does the virtual 7.1 claim actually deliver when I plug the adapter into my PC or console?

The built-in 24-bit DSP processes stereo sources into a virtual 7.1 surround field and raises output volume by 15%, giving positional cues in games without extra drivers.

Does the USB interface limit audio quality or sample rate compared to an internal sound card?

The USB connection carries pure digital audio to the 24-bit processor, enabling plug-and-play operation on Windows, Mac, Linux and consoles with no driver installation required.
