I want someone to build me a unique HD amplifier for headphones. It should work with any headphone / earphone. Should be small as possible prefer 3 (w) x 2 (L) x 1 (H) should use components that are highly reliable but cheap to make in large quantity. This is not just a 3D design project do not bid if you don't know how to design build the circuit , design should be unique and i should be able to get it patented , and all designs and circuit rights should be handed over to me at the end of the project. You will have to send me the circuit to test and release the payment.

Please do not bid without reading the description.
