just got these a while ago..um3xrc.
comfort is topnotch. the round housing is indeed comfortable, i would say otherwise in regards to the memory wire, time to get used to it again ala tf10 days

too much tips on the package only used the gray one, seems it gave a comfortable fit, will try other tips maybe sound may change, though i like the sound right now...
isolation is top notch, when music is on even at low levels, external sounds/environment is silenced or muffled (jeep horns). used the gray tips.
seems like i wont be missing so much of the sm3, ive read reviews that this iem is boring and purely for stage monitoring purposes, yet i find it good for the music i listen to, mostly acoustic and instrumentals... though i miss the bass of the sm3 (in regards to rnb music)... but the bass on the um3x is good, not as thumpy as the sm3 per my recollection but presence is definitely there, but one thing that calls my attention each and every track i listen to is on how the musical instruments are separated... which i liked...
well that's it... im not good at reviews and above are my impressions.
this iem might not be for everyone, but i guess i made the right choice...well confirmed with the poison master bro shoks (pk2?

) and the um3x guru bro mikado..

worth it... this might be my end all journey towards iems... until customs
