I must repeat that I did not listen to the Live with any pre-conceived notions of its sonics at all (apart from a Facebook comment from Warren P. Chi along the lines of, "They do what the Tia Fourte's do and more!") But, I can confirm that them and the ME are more different than they are alike. Just wait 'til you hear it.
Wow..Tia fourte must be terrible given the reviews for UE live so far...
Back to track, UE live has been designed for stage musician rather than audiophiles which was emphasized in their marketing. For stage musicians, i am not so sure if a big soundstage, super detail retrieval or perfect separation will be their top priority when using IEM for their performance. When compared with current hybrids like legend x, tia trio it certainly sounds "bloated" not as technically proficient in a sense. But UE live does have a smooth, organic and full bodied vocals that I can listen for a long time without fatigue and I am sure a stage musician would probably value for long shows. The timbre and tonality is accurate as well for instruments and vocals alike, well except for cymbals which sometimes felt to bright. I was fortunate to be one of the first few to listen the UE live (or unfortunate cos its not burnt in) and it did give me one of the most memorable impression from all the recent flagship IEMs i have listened to.
