I've been swapping between them a lot lately, so I can answer with some confidence now. Keep in mind these are with fully modded Jergpads (with open vents).
Focus (and ""-A) pads are significantly more comfortable, that's definite.
In terms of sound, Jergpads are much bassier, with a fuller midrange, better tone and timbre in general, and more realistic imaging, with a more "out of the head" soundstage.
Meanwhile, Focus (and ""-A) pads deliver smoother treble, cleaner more accurate bass, better detail extraction / transparency in general, and more precise (albeit more closed-in) imaging.
As you can see, I've been struggling deciding what to just go with, ultimately I may just use one solution for a few months, swap, and vise versa.
Do you still prefer the Focus-A to the Focus?
