I dont dislike the look of the NA2s but the Starseas are a winner in that department, good thing that the starseas are actually pretty standard sized so fit isnt a problem for me, although i wouldnt be able to sleep with them like i do with NA2s, they create too much pressure in the ear and might wake up "deaf". (Note that NA2 has 2 vents and Starsea only 1)
Also the included case with the Starseas is more of a display item, its too big to carry it around in your pockets but too small to fit a bunch of iems, cables and tips.
Unlike the case included with my XINHS cable.
But yeah, treble wise the Starseas are wonderful, cant call it "TOTL" as these are the most expensive iems ive heard, so ill take your word for it.
When you can give this a listen if you havent.
