Ok, define "sound quality"
My point is, they are similar in price, so they will probably be pretty close in terms of overall performance, but with different sound signatures, so you should probably choose based on your preferred sig rather than other people saying which is "better."
+(Σ i = 1 > ∞)(i)
I've said it quite a bit already when I did my comparisons with the other IEMs. Preference will make a bigger impact over technicality. I prefer these over the PFE232 (signature reasons), but they are not technically better.
