Beware that there may be no corellation between the mics shown in publicity photos and those used for recording that singer. Look at your last picture, for example. Only a publicity agent and his tame photographer would set up a studio condenser mic to be in that position relative to the pop shield and the singer's mouth.

If you have $500 to spend on making better vocal recordings in your home studio, put $400 into acoustic treatment and $100 into an SM58.

The 3rd photo seems to be a new mic that capture audio through the xlr connector and that's why they put the pop screen there... NOT !!!!hehe

I read that you have a Blue Spark Digital. What's wrong with this mic? is it the USB version? if not what's your audio interface and preamp ? What about monitors, room treatment ???
The best way to choose a vocal mic for yourself is to shutdown the computer, walk or drive to the nearest music store and try some mics or rent some to try at home !!!

Bos said it...

To answer your original question(s), the top pic looks to be the body style of a Neumann U87. The middle could be an AKG SolidTube - of which you could probably get one for around $500 but they've been discontinued and had a reputation for service problems... The fact that the pic shows two teenage girls dancing around the mic in a music store setting tells me it's probably not a high dollar mic.) ;) ....and the third mic might be a newer Telefunken 47 . I'm making educated but rough guesses here. My eyes ain't what they used to be.

Now.....we are looking at pictures that aren't up close, so we can't see logos or details that could emphatically tell us what the models are, and even though the mics may look like U87's or 47's, That doesn't mean that that's what they are. Many cheap mic manufacturers are designing their styles to appear aesthetically similar to classic high dollar LD condenser mics... and aesthetics get you nothing. There are more than just a few cheap LD condensers on the market that may appear to be very similar to mics like U87's, U47's, U89's, ELM's, etc... but looking similar is a far cry from sounding similar.

It's all about the sound and quality of build and materials used.

If you are asking if you can afford any of the mics in the pictures you posted for the $500 you have to spend, well, maybe, if they are cheaper knock-offs.

But, if the mics in the top and bottom pics are the real things, You're not gonna get any of them for even close to your budget.

U87's: $3500 US
Telefunken U47: $8500 US

FWIW
