A definite upgrade over on board sound. The SPDIF option makes this a robust solution.
The Xonar upgrades your existing built-in sound card. Increased output with no distortion and no hissing or humming. Worth the price because of the sound quality it provides.

1. WOW the sound really is that amazing!
2. The software that comes with it offers tons of features that would suit anyone! On the CD it has the driver, the software with all the features is an optional installation.
1. I wish it came with an adapter that allowed RCA to USB so I could use not only my RCA headset with it, but also my USB headset.
2. The mic sound quality was no better than the quality of the on board sound port of my laptop.
I think this tiny little card has a pretty big punch when it comes to quality of sound and all the features that the software that comes with it. Of course it gives you a choice on whether you want to install the software, or just the driver.

It's sold me on ASUS sound cards for any internal purchases for sure! If their external sound cards sound this great then I'd buy their internal ones now.

I should mention I initially bought this to hopefully eliminate some mic sound issues, but it didn't shield from EMI like I had hoped in regards to the Mic. The Audio is great with music. I can use this on my laptop. But can't say much for the Mic part... it just didn't offer any sound quality there. It's no better than me plugging into the on board port of my laptop.

I say Very Good would purchase again because the price (which I bought on sale) and the quality of the audio is really good. Although I don't think it's grounded/shielded like it says it is on the manufacturers website.

Amazing sound quality, it's so obvious when compared to default on-board sound card.
If you search a bit online, you will know why external sound cards can beat internal ones(even the high-end ones) so easily. But hearing the difference by my own ears still make me shocked. I am happy that I picked this.

Small size, great sound, decent price
Could have a better amp but that is a limitation of USB
Bought this for a SFF LAN machine that needed something better than onboard. I use Sennheiser 350s and I was happy with the sound of this card. The USB extension is nice. On Win 8 you have to download beta drivers for this to work.

Sound Quality
Wow sound is awesome, very good replacement for onboard sound for laptop. i use it on my Asus G75 with Sennheiser HD558 and the quality is almost the same than my Asus Xonar DX in my desktop pc.

Experience: 7 Months
good product
nice sound
good replacement sound for crappy onboard! and it's enough to power my headphones, very clear sound too

So much better than laptop sound
Improve sound quality significantly even when using crappy headphones/speakers.

-Amazing sound.
-Great software.
-Sounds way better than my laptop's built in sound card.
Bought it to get better sound quality on my laptop and it does exactly that. Love the software it comes with, awesome effects and powerful EQ. I love it!

Experience: 7 Days
 Verified Owner
This is far more powerful then i thought. I am constantly finding new uses for it. well worth the premium.
Although small, it is still bulky enough to be a nuisance(if you use it as amp for portable players).
So far i have plugged it in to a computer, a keyboard, a cell phone, a laptop with linux, and a tablet.

the increase in quality and volume increased by a huge margin over the respective audio systems.

i understand now why there is a key ring, but i would have made easier to take off of key ring when needed.

Experience: 1 Days
pretty much plug and play, dont need the cd; maybe unless u are using the 3d and surround stuff...
It might break if I smash it with a hammer.
I compared my new laptop with my old laptop and desktop with onboard sound...I could confirm it was my new laptop which was not being able to play my speakers out like they should with the headphone out it was half as quiet with the same volume level...I bought this and it's fixed, and if not even just a little better.

Comment: My experience with the Xonar U3 really showed how far average sound card technology has progressed. The fact that one piece of the chain toward very good sound quality can be had for under $100 and in such a small package is absolutely brilliant.
Posted by: ilya @08/23/11
Comment: If your system has a free PCI or PCI Express slot, you'd do well to populate it with a Xonar sound card rather than filling one of your USB ports with the U3. The USB Xonar's signal quality simply isn't good enough, and its lack of high-definition audio support is difficult to ignore. As
