5 out of 5 eggsWow. Night and day.

Pros: Bought this solely to listen to mp3s all day on a work laptop I'm about to purchase, and to maybe get better sound out of my 3 month old "ASRock Fatal1ty Z97 Killer" motherboard in my desktop. A lot of people say it's a waste of money for a new motherboard, because your onboard sound is just as good. I thought, "Meh, what can it hurt?" If you have that ASRock motherboard, this is a HUGE upgrade in both power and clarity.

Playing mp3 files through my Sennheiser 558 headset, it's like night and day. Sounded great before, but now? Wow! Goosebumps. Much better clarity, much more open soundstage, regardless of volume. I'm hearing things in songs I haven't heard before. And it hits like a truck at around 40% volume, with no distortion (at least on the 558s).

Cons: None, especially for 40 bucks (really???), and I can use it with the laptop I'm about to purchase.

Other Thoughts: It's just plug-and-play. I first installed the driver from Asus' website, and the U3 didn't work at all. Uninstalled, rebooted, and I've been giddy ever since.

5 out of 5 eggsWorks well under linux

Pros: Worked immediately when I plugged it into a Dell M3800 running Mint Linux. Had to select it as the output sound card, as one would expect in a machine with multiple sound cards. No drivers required, no command line stuff. It. Just. Worked.

Cons: The volume adjustment provided by linux goes from nothing to kinda-loud without any steps in between. I don't know if that's the device or linux, so I didn't deduct any eggs.

4 out of 5 eggsAmazing USB Sound Card

Pros: Decent sound quality @ 46kHz. DAC is asus ua100. This uses the Texas Instruments DirectPath DRV601 for headphone amplifier. Built in charge pump for negative voltage; uses direct coupling instead of capacitive Quite loud for a 5v@500mA power supply (USB) . Much louder than my Xonar DGX "Gaming headphone amplifier"(which has +-12v available.

Cons: DRV601 is rated at >= 100ohm output impedence. Asus is using this chip out of spec. Might not last forever.
Housing is rediculously large for the size of the board and kind of ugly. the 2 blue leds are pointless and just waste a few mA.

Other Thoughts: Overall a good buy at under $40. Works well with my crossfade M-100. Can put a concert on my head and take it with my laptop.

5 out of 5 eggs

Pros: Bought this to provide a working mic port for a laptop with a broken port. Not only does the mic port work great, but the sound is stellar as well. Using it with a Logitech G230 headset.

Cons: n/a

Other Thoughts: Windows 7 doesn't default to the Xonar U3 for sound and microphone usage after unplugging it and then plugging it back in. Not really a problem, just minor a nuisance.

3 out of 5 eggsYou get what you pay for.

Pros: It works and gives great quality sound controls.Great alternative if you have a mediocre soundcard already and want a little bit of a boost. I am currently using a laptop and bought the card just for that. Was satisfied with what I got out of for the time it lasted.

Cons: It was either a faulty product or just got worn out too fast? I tried configuring and diagnosing the problem myself and got nothing about why it would just die out on me. I had it plugged in at all times but nothing was touching it to hinder the movement at all. The lights on it still light up but next to no sound at all through my Gamecom headset.

Other Thoughts: I won't be purchasing an USB soundcard anymore after this experience.

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...
