It is a condenser microphone condenser large diaphragm, whose only method of connection is USB. It has three modes of mitigation (lo, med, hi). The design intended primarily for voice recording. There is no need for drivers on the computer to see it work. The USB as a USB 2 work, the microphone is recognized as an audio device in its own right, he should select in the "registration" of Windows or OS X.
I have been 15 days, and also produces a special, it's crazy the number of services that makes me. I have owned in the past a static micro-behringer b2 pro, a mixing desk and a Tapco blend6MIC100 preamp behringer. Sure, the three products I just mentioned offer better sound performance. But the implementation is unbeatable on the MXL USB.006: we connect the USB to the computer, it saves the software (Audacity, SoundForge, Cubase, Logic etc), and it is in the box. In fact I use the MXL very often because it's fast, convenient, efficient and portable (a nice cover is provided).
Question sensitivity and loyalty, I find it all at entry-level static, so enough for a model from speech to singing, to the registration of any type of sound effects. I like its sound characteristics for voice, frequency response is compelling. It produces a slight background noise depending on its location relative to the computer, in fact it is mostly a USB cable which I think is poorly shielded. Trying several positions of the cable can be reduced or eliminated the background noise.
For 100 euros, it is a very practical solution for the person who is not already equipped with mixing desk / preamp with phantom power, and using only their computer. Its table-top tripod is perfectly studied, no need for a microphone stand. As a composer / sound designer, I love it and I use it very often, instead of a solution "home studio" more complex (micro preamp + + table) that made things less spontaneous.
