I bought these after quite a lot of research and hesitation to spend this much on IEMs. I'm glad I did.
Make no mistake - these are basshead all over. However, I found them to have a lot of detail and depth I've never heard before in IEMs (I topped out in the 100$-ish region in the past). I even found that some of my closed headphones don't come close. They can have that typical open-can effect of turning your head around because you thought you heard a sound from behind your shoulder. But it's always from the music.
You get plenty of tips and I found the foam ones to be the best by far. The foam seems to be of good quality and doesn't show signs of disintegration after 6 months of ~5 hours/week use.
I would have liked a more clever solution for the carry case, though. It's too cumbersome to always store them in there when on the move/putting them away for a while. I tend to carry them in my pants' pocket which just doesn't seem right for this price tag. Maybe this is just me though.
