USB 2.0 5.1 Audio Adapter with Microphone Jack Review
Many newer PC motherboards come with an integrated audio solution. Some of these integrated audio choices work well and some leave a lot to be desired. However, there are still a few motherboards without integrated audio and some legacy boards may lack this feature as well. If this is the case, the folks at USBFever have a handy solution =96 the USB 2.0 5.1 Audio Adapter with Microphone Jack. This small USB device offers many features found in a PCI sized audio card. Included are stereo 5.1 sound effects, virtual speaker shifting, surround sound and more. Plus this USB dongle has a jack for both speaker/headphones and a microphone.
