I don't talk about customer service, i know they suck in this area. For fitting, i always have this question, what it mean by perfect fit? To me the seal is already there, the only different is comfortability. Because all we talking here is by word, only imaging, guess... so until now i still don't know what is perfect fit. To me Roxanne sound good for some track, the thick sound make some track awesome, i think you like it bass which i like too but the high i just feel it veiled. For general i much prefer MH334. There is some magic with the Roxanne, the SQ become very good after sometime of wearing it because of Brain burn but when comparing with other i just prefer other. I think just my preference.
Since you got the universal one, maybe we shall meet up to test out all your tips available and compare to my customer version
