this is a guess.
does a external noise reducting headphone even look like this?
well, i wanted the mic to create a negative version of the noise outside and well...silent it.
the mic amp feedback resistor's (R5), resistance can be changed with a screwdriver.
the chip is a opa4134, a quad version of opa134, for stereo input and 2 mics.
will it work?

As I understand this technology, the microphone must be inside the earcup. The microphone amplifier must include an input from the headphone driver for cancellation of the sounds that you want to hear.
A microphone on the outside of the headphone would be ineffective because it would not have the ability to detect what your ear is hearing on the inside of the headphone.
