The CAD Audio GXL2600 USB Mic is new microphone from the fine people at CAD. It is closely related to their GXL2200 series mics, however, this has a USB connection instead of a XLR. It is an incredibly durable and high quality mic. Many USB mics do not sport a headphone out, they assume you will be monitoring via another device or through a mixing console. I have posted the link to CAD Audio's website where you can find the page for this product, I hope this helps!
