The Xonar U7 soundcard has won the Gold Award from Vortez. They state, "The ASUS Xonar U7 is full of functional features in a fantastic finish giving fine fidelity. Deserving of our Gold award."

The wonder of incredible compact audio!

Xonar U7 serves the needs of PC gamers who want to enjoy strong and clear sound via headphones, and is also ideal for listening to music as it produces much more impactful and detailed audio than onboard hardware. Connecting via USB, it requires no standalone power supply and works instantly setup-free with no need to open the PC case.

Powerful sound from a compact and portable device

Xonar U7 engineering overcomes the space and power supply limitations of other external USB-based audio devices to offer precise and immersive 7.1-channel surround. Sound processing uses 192kHz/24-bit fidelity for true high definition output, maintaining consistent quality across all surround channels.

114dB signal-to-noise ratio (SNR)

Up to 16X audio clarity compared with the SNR ratios of average onboard audio.

Hyper Grounding technology

Exclusive ASUS Hyper Grounding PCB fabrication ensures strong signal insulation to reduce distortion and interference, also known as component crosstalk.

Digital to analog converter (DAC)

High quality Cirrus Logic® CS4398 DAC (digital-to-analog converter) brings clarity with excellent signal-to-noise ratio (SNR) and low total harmonic distortion (THD)

Integrated headphone amplifier pumps up every sound detail

Since many gamers choose to refrain from disturbing others while insisting on the best sound quality, Xonar teams integrate a headphone amplifier on Xonar U7 to boost immersive headphone output.



Gamer-friendly design

Microphone and master volume controls

Dedicated controls allow gamers to quickly adjust master and microphone volume without pausing games or going into software menus, ensuring uninterrupted action. The master volume control doubles as a clickable switch for selecting between headphone input (front panel) and speakers (back panel).

USB convenience

Xonar U7 connects to PCs via USB. It also gets power directly from the USB port, removing the need for a power adapter. Combined with its compact dimensions, these turn Xonar U7 into a highly portable audio-enhancer that can be easily carried and placed anywhere.

I was getting coil whine in the headphones with a pci card in my pc, OC replaced it and it was still the same so i thought i would try this, its a great little usb sound card that sounds great with my razer kraken pro v2 heaphones and the dolby home theater 4 and xonar u7 software is good for customising the sound, i have this on top of my pc case all the time and there is no coil whine or anything.

Great Sound. Easy to use.

Absolutely the best music from a Computer I've ever heard.
So easy to use:
Plug it into an unused USB socket, preferably USB 2.0 or above. Comes with USB A to B Cable which is what you'll need to use. I bought a better one, but I'm sure the one supplied will suffice.
The Disk that comes with it is a waste, very out of date. Download the Driver from the Asus Website here for Windows 10 (older sound cards are catered for on separate pages):
Use the v1.6. Run set-up and it'll do some stuff and ask you to Reboot. Once you're back, Audio Center and Dolby Home Theater 4 will be there waiting...then you can play with the settings for a while. :)
Once you've made your set-up choices, the 2 Programs can be shut and the sound's sorted. You might need to reload them in future to switch from Music to Game Settings, for example.
All very simple. :)

Great External Sound Card.

Just bought this to go with some AKG K612 pro headphones and I am very impressed with the output. Gives a nice clean sound and the Dolby Home Theater GUI is intuitive and effective.

A great solution for if you have no space in your pc or want to remove any worry of EMI.

Full review of this coupled with the K612 + modmic can be read on the overclockers forum here -
