I own a good number of high end universals and customs and when I bought the Shure SE535s a few months back, I expected them to be outstanding from the reviews. However, since then I have realised that they have:
1) Absolutely no sub-bass to speak of
2) Rolled off and recessed highs
3) Sibilance not present in the SE530s
I wish someone had put this more explicitly in reviews when I purchased them. However, the mids are very smooth.
