U18t for me is a whole different world for sure. They as natural as $2000 level big cans and they can provide micro dynamic like T1.
If use 3 phrases to describe U18t to my ears, will be natural, life-alike, high-end.
They are pretty much a all rounder, but not like k10 or some other well known all rounders, they give the music life. You can almost feel and see there is a band right in front of you, this is the most impressive and magical part, which I didn’t even get from se master-1, hd800s, LCD-3, T1 level big cans.
But they also have some parts can be further improved, such as they can be more full bodied in some parts, and the sound stage could be deeper. They tend to be flat compare with those big cans(I know it’s a little bit unfair), when play genres or records which require huge dynamic.
