While a microphone for your computer can cost less than ten bucks at your local Radio Shack; you get what you pay for, and you're paying for a substandard peripheral with about as much function as Styrofoam boat anchor.
Considering the emergence of voice-over-net communications and speech recognition applications, the modern PC user needs a high-end mic. Enter the Telex Super-Directional USB Digital Microphone M-560, a digital microphone providing pro quality, digital audio input directly to your computer. Its exclusive "Acoustic Directional Processing(TM)" focuses reception on the user's voice and rebuffs all background noise. It makes for crystal clear conversations and precision voice-activated invocations that used to require a lip-chummy headset.
The M-560 is also a USB device, which means your PC does not need a sound card to accommodate it. Just plug 'n play and you’re on.
