The stock ones won't be BA so they won't be subject to the same variance and no danger of them unmasking the crackling, the DBA-02 is probably going to be OK given it is rated at 43ohms (I'm assuming at 1KHz) - it will be less at lower frequencies but unlikely to cross under 16ohms. I can't actually find measurements for the DBA-02 however to confirm that, would recommend trying them out with an S4 and some bass heavy music to check.
I've see a graph for the Brainwavz b2(which i think is the same as the dba-02) and the impedence looks like it stays well above 25ohms in the lows but drops down to about 20ohms at about 8k. I'm a complete newbie at this but that's how the graph looked to me, so i presume that would be okay? Thing is, that's the dba-02 mki but i have the mkii's so i don't know if they are significantly different.
I listened to both the s4 and the HTC one in the shop today with the Fischer's and couldn't notice anything although they both hissed slightly if you listended for it(although my iphone 4 also hisses slightly). The biggest problem is that the s4 demo units have no actual "songs" on them, just weird studio tracks making it difficult to judge the sound. The HTC sounded pretty good.
One thing i found weird is that everywhere i've read that the S4 is quieter than the HTC but the s4 I tried was actaully ear-splittingly loud! I couldn't even turn it a third of the way up without hurting my ears.
I think i'll just have to make a choice, get the phone and cancel the contract within the 14day period if the problem shows up.
