What it is

The zdyCGTime 682559181180 is a USB 2.0 external sound card that adds a 7.1 virtual surround channel to laptops or desktops. It connects through a standard USB Type A port and provides a 3.5 mm stereo output plus a mono microphone input. The unit draws power from the bus and requires no external supply. Driver-free operation is supported on Windows 98SE through Windows 7 with USB Audio Device Class 1.0 compliance.

Who it suits

This adapter suits users who need a quick way to add headset and microphone connections to a system lacking functional audio ports. It works for basic gaming, voice chat and media playback where virtual 7.1 enhancement is desired. Buyers who require hardware-accelerated surround decoding, higher sample rates than 48 KHz or professional recording SNR above 95 decibels should look at dedicated internal or higher-spec external audio interfaces.

Capacity and headroom

The device delivers virtual 7.1 channel audio at a 48 KHz sample rate with a 95 decibel signal-to-noise ratio, adequate for stereo headsets and entry-level surround simulation. The built-in amplifier drives typical consumer headphones and the inline volume and mute controls provide convenient level adjustment. It will not satisfy multi-channel analogue speaker sets that demand discrete analogue outputs or applications needing bit-perfect playback beyond the USB 2.0 full-speed 12 Mbps bandwidth.

Questions about this item

Does the adapter need a free USB-A port on my PC?

Yes, it plugs into a standard USB-A port and draws power from the bus, so no external supply is required.

Will my existing 3.5 mm stereo headset work with the 7.1 virtual surround feature?

The stereo output jack accepts any 3.5 mm headset; the bundled Xear 3D software then simulates 7.1 channel audio on Windows XP or Vista.

How can I confirm the device is active after plugging it in?

Windows lists it as a USB Audio Device, the volume and mute buttons on the unit respond, and the Xear 3D control panel shows 7.1 channel output.
