Whether you are a music buff, gamer, or into multimedia, upgrading your notebook sound to the ASUS U3 is going to be a huge jump in audio quality. Frankly, for the price, the ASUS U3 offers far more quality and performance than one could possible expect. Throw in great features and software, and it is pretty much a no-brainer of an upgrade for notebooks, and for many desktops as well.
A USB sound card can be a convenient and effective way to improve sound quality for a laptop or netbook, which might have less than impressive audio capabilities. The ASUS Xonar U3 USB sound card is a perfect example of this, and it just works extremely well for most of what it does. The ASUS Xonar U3 USB sound card earns both the "Good Value" and "Recommended" awards as a portable, convenient, and cost effective upgrade to most laptops and netbooks.

…It didn't take long to grow dissatisfied with the ultraportable's music playback quality, though. The built-in audio feels flat and lifeless; bass lines lack punch, high notes are a little dull, and the middle of the spectrum sounds muddled and distant. The Xonar is a huge improvement on all fronts and across multiple musical genres. Ultra-high-bitrate MP3s …sounded substantially better on the Xonar. The U3 also lacks the faint background hiss I've detected with integrated audio solutions… The U3 sounds so much better than my ultraportable's integrated audio that it's become a permanent fixture in my notebook bag.
…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. … Dolby tech make this makes this an ideal candidate for any mobile gamers and movie watchers. …the overall sound is very clear and enjoyable. …For approximately $55 the Xonar U3 USB sound card can be yours. For what it offers and at that price, there's no reason - especially for mobile users - not to grab it.
