I am very interested in these IEM as they purport to be very flat and thus detailed earphones. The only question I have, which unfortunately seems to be mired in debate, is the difference in the B, S, and P versions. As I understand it, the S and P are supposed to be the "same" except for the S having more resistance (~ +70 ohms) than the P. There also seems to be at least some consensus that all three are actually the same earphone with the B (binaural version) having both the higher resistance and a high frequency boost in the cable. I have also read conflicting information that the B version is a different animal altogether, in other words, it's a higher impedance earphone with additional components within the driver itself responsible for the high frequency boost (or at least without having anything to do with the cable alone.)
Regardless of each version's sound signature, what I would really like to learn is if it is possible to start with, say, the ER4S and then be able to modify the earphone in such a way as to realistically have access to all three versions? I know that going from the S to the P is simply a matter of adding the appropriate resistor(s,) but how would one account for the increase in the frequency range of the B version? Adding capacitors to account for the appropriate value, or is this even possible? I have read conflicting information regarding the issue and was wondering if anyone knew the case definitively? I have searched for these questions here on head-fi, and to be honest, it's quite confusing to me so I figured I'd be better off starting a new thread. I am hoping to hear something along the lines of being able to switch between both the S and B versions simply by swapping cables. Thank you!
