I would be very curious to hear about the difference between the Noble 4 (universal) and the Noble 4C (custom). I do completely understand the difference in design etc. and that they may use similar driver implementation? On the other hand I'm very keen on learning how similar, if any, they are to each other regarding sound signature and their overall presentation.
If I presumable,experienced/managed to achieve a perfect fit with the 4C custom and if I encountered the same with the Noble 4 will they sound the same?
I believe that this is a very legitimate question. On the other hand if the N4 and the N4C uses different drivers and/or implementations. My questions are completely irrelevant but others may still have an interest to make their own opinion..
