USB Audio Adapter With 7.1 Virtual Surround

The 1Mii S03 adds separate 3.5 mm headphone and microphone jacks to a computer or console through a single USB port. It delivers 7.1 virtual surround sound at a 96 KHz sampling rate for wired headsets. The plug-and-play design requires no driver installation on supported devices. A six-foot cable provides flexible placement on a desk or entertainment unit.

Users With Broken Or Missing Analogue Ports

This adapter suits anyone whose built-in audio jack is damaged, blocked, or absent, and who needs a quick way to connect a standard headset with separate mic and headphone plugs. It also helps gamers and remote workers who want hardware microphone mute and volume controls within easy reach. Buyers whose headsets use a single combined 3.5 mm TRRS connector or USB-C will need a different solution. Audiophiles seeking discrete multi-channel output or higher sample rates should look elsewhere.

Inline Controls Replace Software Mixers

The built-in mic mute button and mic volume wheel let users adjust voice input instantly without opening system settings. A headphone volume dial controls overall listening level directly on the cable. These hardware controls work independently of any operating system or application, so they remain functional during full-screen games or when the OS audio service hangs. No bundled software or driver disc is included.

Questions about this item

Do I need a free USB port on my computer or console for the 1Mii S03 to work?

Yes, the S03 connects through a single USB port and draws power from it, so an available USB socket on your PC, laptop, PS4 or PS5 is all that is required.

Will my existing 3.5 mm headset plug straight into the S03 without an extra adapter?

The S03 provides separate 3.5 mm headphone and microphone jacks, so a standard dual-plug wired headset connects directly with no additional adapter needed.

How can I confirm the 7.1 virtual surround mode is active after I plug in the S03?

Press the surround button on the device; the LED indicator lights up to show the 7.1 virtual surround mode is engaged.
