Donny, both of those are omni-directional condenser mics, which are specifically set up for speaking, lecturers, etc... They don't seem to work well with singers, at least that's been my experience with them. And, when you look at the specs, they pretty much tell you that is the case. When I had the E6, and had horrendous feedback problems, I called their tech support and they told me the E6, even the super cardiod mic, was not really intended for solo singers. They said it was better suited for choir members and female vocalists. And, therein lies the problem. Seems like the headset mics with the larger footprint are better suited for male vocalist.
