5 out of 5 eggsFeel the music

Pros: Sound Quality high, its own equalizer software, it has spdif attachment, indicator light isn't bright to annoy a person trying to sleep and very very simple to set and forget.

Cons: Its probably me, but when I do voice or voip communications people sound like an all mighty being. I am sure this isn't the device its probably me not putting the correct setting on the equalizer software.

Other Thoughts: These usb sound cards are not necessary just to have sound, but if you need to separate sound like video games and voip communications(you can do music if you want but most people already have awesome speakers and sound cards). This is the best one for your buck as for sound quality and simple to use.

5 out of 5 eggsExcellent with reasonable expectations

Pros: Very easy to install and setup
Solid sound for a USB card
Reasonable price
Flexible uses
Built in headphone amp

Cons: Given what it is and the limitations of a small USB sound card - none.

Other Thoughts: I purchased this after the front audio jack on my full tower Cooler Master case failed. its so large I really didn't want to deal with the hassle of reaching around my desk to plug my headphones in (since I use them on several devices). The U3 solved the problem perfectly allowing me to use them on a front USB port. The sound quality is pretty good - comparable to the Realtek ALC892 chipset on my motherboard. I don't use the Dolby headphone settings - I prefer just the stock 2 channel sound with tweaking on the equalizer for my games (but you do have the option). The headphone amp is effective - I have to keep it on medium, so there's definitely a little headroom for better quality headphones with higher impedance. For $30 after rebate it definitely fit the bill for me and the problem I had with my case.

5 out of 5 eggsBest USB sound cars

Pros: Very best sound card you can get if you need an external one. Good software and plug n play. No trouble at all setting it up.

Cons: Wish it had optical audio but in the pics it clearly doesn't show it has one, just wish it did. But for that price you can't complain at all.

Other Thoughts: Packaging is dope.

5 out of 5 eggsVery cool sound card!!

Pros: Takes away any internal noises from my laptop's internal sound card. Love it cause it's small and light and yet comes with a great equalizer and sound effects software. I'm very happy with this device, would recommend to anyone!

Cons: None yet.

Other Thoughts: Be sure to right-click your volume icon and select this device as your default playback device! I was puzzled as to why this wouldn't work until I figured it out, duh...

5 out of 5 eggsSimply the best USB sound card in its class

Pros: Superb sound quality across the range
Dolby Headphone - done right
Dolby Pro-Logic IIx for stereo/5.1 to 7.1 upmixing.
USB like size, very easy on the table - no clutter.
Dolby Digital Live real-time encoding over TOSlink Optical out
Outstanding surround sound with Dolby headphone in 7.1 playing games/movies (more on this below)

The flat non-DSP effects sound of this card is warm to neutral depending on your headset. And with equalizer tweaks it sounds great on highs and perfect in the lows. Bass is not over powering yet just at the right level. Even bass freaks will be happy with its bass, granted the equalizer can give out more bass if needed. The mids were also great. I trust my ears, not the RMAA analyzer.

Great Stereo sound, thats all fine. What about surround sound? This is where this little gizzmo truly shines. The surround is not muffled or hollow sounding, its just perfect and the best part is that equalizer settings can tweak the feel even more. Positional audio is

Cons: None really, for the ultra small size this thing is simply amazing.

More on the Surround sound since there is a 1000 word limit on each section.

I tested the THX Tru Surround on the X-Fi 5.1 pro, Sharkoon's own SCU hardware solution and the Xonar U3 in game and movies.

In games they all sound great, but Xonar U3 sounded more natural with positional accuracy so good that you can really tell the various angles from where the sound is coming from. Proper audio cues. Sharkoon SCU was good in positional audio but there is something about the over all sound that makes it more like a small sound stage, only slight though. THX was accurate as Xonar U3 in positional cues but the sound quality was no better than the Sharkoon SCU.

In movies the THX Tru Surround was terrible becuase its using only two channels, switching it to 5.1 in windows panel made sounds just getting lost over non-existent channels. Sharkoon is digital input so no such troubles. Xonar works fine as 7.1 in windows

Other Thoughts: I bought this from another place since newegg didnt have this in stock at the time. I paid 20 USD more to get it but even then its great investment. So newegg's price is a steal.

A little background into why I needed a USB sound card anyway. I got this Sharkoon X-tatic SR surround sound headset and then remembered my M18X alienware will not output a 5.1 digital signal over SPDIF. Its just Stereo PCM. TBH I should have given it more thought before buying the headset. But the believe me the headset was very good and worth the investment. So I got the Creative X-Fi 5.1 Pro USB

The X-Fi 5.1 Pro USB was good on sound quality and did what I wanted which was optical out with Dolby Digital live encoding over TOSlink optical. Worked fine with the Sharkoon's SCU sound box with optical input feed, Dolby headphone surround sound through the Sharkoon's SCU sounded great.

But getting the Xonar U3 made the X-Fi and the sharkoon's SCU redundant, it just has a better Dolby Headphone implement

5 out of 5 eggsGreat for high-end headphones

Pros: The onboard headphone amp does a great job pushing higher-impedance, high-quality headphones. That's the main selling point - high-impedance headphones that don't have their own amps built in, like my Sennheiser HD555s, will suffer poor response at high and low frequencies when plugged into almost all computer sound cards.

Very similar to the Xonar DG in terms of features and software/drivers, but USB means you can hook it up to your laptop, as well.

Has a mic jack, as well, so you can run your game-chat mic through it for convenience.

Cons: Limited to 5.1 output, so not the most useful thing to plug your laptop into a 7.1 system if that's important to you.

Audio input doesn't support ASIO, so it's not a suitable device for any kind of serious audio production.

Other Thoughts: You can get separate headphone amps, as well, and get a lot of the sound quality enhancement that way. But they cost about the same amount of money, and Windows doesn't remember volume and equalizer settings when you switch between a headphone amp and speakers.

The best use for this is flat-response music and movie listening for audio snobs. If you want something more thumpy and in your face, this'll work (even with your fancy 5.1 headsets), but that's really more what speakers are made for.
