Been looking for this External sound card. Very popular brand would be Creative (check comparable Creative Xi-Fi 5.1 USB Surround card $77@MSY), but hey.. for 50% sale of normal RRP, i'll give this one a shot.
Suitable for those of you looking a better clarity of sound for your home/music entertainment. For more information, check on youtube/Amazon.
Cheers.
Something comparable to this would be the Creative Soundblaster X-Fi Go. I don't think the X-Fi Surround 5.1 Pro would be a suitable comparison to this.
