Do the iems have too sparkly treble?

If the SE530 is anything to go by, then yes, the SE535 might have treble problem. It's not bright, per se, but it has a very sibilant spike in the lower treble. It was a huge shock to me, especially after hearing so many reports of dulled down Shure treble.

Agreed.  It's a bit grainy and un-natural.  Decay is terrible versus UE900 or W4

This is exactly what I am trying to say from the beginning!!!!! (my English is not so good though..)
 
Than it might be a faulty batch. it is the only explanation I can give for their terrible treble that messes up the whole sound.
 
As of the sound files quality, all my tracks are 256 and up.
