I am using a basic mixer (Alesis MultiMix 4 USB), my laptop (which I connect to my TV via HDMI), a usb interface that allows my usb mixer to get along with my laptop, to put it simply, and everything is connected to the same power bar. The mixer and interface are a good 3 feet away from my laptop + TV. The mic is connected to the mixer, and I also have studio-compatible headphones, but I've put them aside, because I feel like matters are complicated enough as it is, especially for someone like me, who is 22, and very new to this type of technology. Pretty ironic IMO. As for what I have chosen for my input device, that would be the usb mixer (mic) which also presents a problem for me, because the mic records my voice (very well, actually) and the beat as well, but not through direct "linkage", but through the speakers of my TV/laptop, which undoubtedly makes it sound like crap. I have a gut feeling this whole situation is on a very light side of the "technical problems" spectrum, so hopefully this explanation was adequate.
