The Oktava MK-219 is a large diaphragm condenser microphone that is made for the recording studio.  It isn't made for live shows and I wouldn't recommend using it outside of the studio at all.  The mic has a cardioid polar pattern and will pick up everything between 40 Hz and 16 Khz.  It also has a

OVERALL OPINION

I've been using the Oktava MK-219 for a few months and it is a pretty cool little mic.  It is good for a number of different situations and has a pretty clean sound quality.  Oktava has a great line of mics that usually sound pretty good and are quite affordable.  This is a pretty unique looking microphone and looks unlike any other mics that I have seen out there for the most part.  I've used the mic primarily for recording acoustic instruments like acoustic piano and acoustic guitar as well as for vocals.  It doesn't have the warmest sound in the world but it will get the job done in a home studio setting.  However, if you are a professional this microphone probably isn't of much use to you.  While it does sound good there are tons of other mics that clearly sound better than this as this isn't up there with the best of them by far.  It is a mid range microphone designed for home and project studios looking to get a nice sounding mic for a nice price.  As long as you don't expect too much from the Oktava MK-219, I think you'll be pretty happy with the sound that you can get with this mic.  However, if you are looking for a top end mic, this definitely isn't it and I would look elsewhere.  Overall, this is a good sounding microphone at a great price, so I really can't complain about it.
