Well this is a little silly as it looks like the backside of a Neumann U87. It could also be a cheap Chinese imitation knockoff since the aspect ratio of the picture looks to be slightly vertically elongated? But those 2 little switches on the left and right side, underneath the screen of the classic looking capsule cage, appears to be the giveaway to me.

And so what is the purpose of this question? Just curious what you really want to know who can identify these microphones? Most any professional can identify this microphone.

Maybe you made this in metal shop in high school??

So I can say to my friend who used this on his album which is to be finished soon, "How did you like that Neumann U87?" Without asking him what mic it is.. so I look like I know my stuff... which I obviously don't, otherwise I wouldn't have asked.

Oh, beautiful! Ask him if it was an original U87 or the newer transformerless U87ai, that uses the same electronics as the TLM103? Tell him, you know that microphone doesn't work worth a damn without a good full "48 volt phantom supply". Not like those other "Electret" (not a typo) condenser microphones that also use phantom power which, can work on much less than 48 volts, that's why so many of them can take a 1 1/2 volt AA battery, because those capsules doesn't need a full 48 volts for its polarity charge, like the classic U87.

Tell him, it's just an amazing microphone and he should unscrew the bottom part of the body, near the connector. Once you unscrew that part, the whole "body" shell, will slide off the internal chassis, in the direction of the connector, revealing the internal electronics on its internal circuit board. You can then also "push in", the little mechanical locking tabs, along the upper chassis sides, near the capsule, which hold the microphone capsule head assembly, onto the body and just lift it off of the body of the microphone, from the chassis.

You can also tell him that you remember the original U87, which actually had transformer outputs, unlike the newer one, along with enough space inside, to accommodate 2 Mallory 22 1/2 volt batteries internally when phantom power was not available, along with a little battery strength meter that showed through a little oval window cut through the body of the microphone. It actually had a little micro pin switch that was in the center of the 3 pin microphone connector that switched the battery on and off when the microphone cable was plugged in, which the newer ones don't have any more.

He'll be amazed! Tell him, he can now buy you dinner.

Remy... hilarious! Thank you for the full biography on the life and times of the Neumann U87.

If I were to recite to him this information he would most likely ask me my name. Then ask me what I've done to the real Dave.

Nonetheless, very interesting. Thank you.
