Now I know everybody loves these phones but I think some things can be improved upon:
1. The fit. These things are sometimes a struggle to keep them in my ears while walking etc.
2. The sound. Be aware that I listen to metal, so my requirements are different to most! Out of the box, I was quite unhappy with the midrange, it was way too thick and the music felt mired in it. After some careful EQ to reduce the midrange however, I was quite happy with them. They do have some very good qualities, but I think I am after something a bit clearer and more impact full. I find these to subtle and smooth, but too much so sometimes.
So to give a bit of perspective, I have a pair of Grado cans, and I love the sound. It's almost perfect for what I listen to.
I also have some Koss KCS75 which are similarly nice, if less refined than the Grado. Hopefully tells you what I'm looking for. I can run these flat, whereas with most other headphones my EQ graph usually looks like a smiley face!
They other thing I should mention is that I am done paying good money for iems with non replaceable cables, so this is a priority!
Also my budget is flexible.
Thanks very much for any suggestions!
