I ownz this.
I just ordered another.
For anyone not experienced with recording, this is a USB mic, with built in preamp and a headset jack 1/8" on the mic body, for using headphones as monitors.
It will not plug into your dj rack, your karaoke system, or your PA. It has to plug into a pc USB and ONLY USB. I has the recording interface built into the mic body. It weighs about 2 lbs.
As for the quality, it's an excellent vocal mic, and mic for pod casting etc. I have used it to have my daughter lay down vocals to overdub into pre recorded guitar. I have used audacity and protools as well, but the SE protools is very vanilla compared to cubase, acid, or any of the other consumer grade suites.
I can also HIGHLY recommend MixCraft 6, which is a great recording suite, for the novice and intermediate audio engineer. Protools is complicated, and the SE version only allows 4 tracks. (Vocal, guitar 1, bass, and drum track, for instance). So if you have a complex piece with more than 4 tracks, you'll need a more full featured suite.
But if you're just laying down a video with voice overs, and maybe doubling the vocals or adding background music, this is perfect.
I want to also add that this mic is somewhat directional, although it's marketed as an Omni,
