neither do i own it, nor experienced it and I wont probably ever but it so cant say. But quick googling gave relatively few reviews and why i wouldnt buy it because of below reasons:-
1) Doesnt seem to have above 4 rating. (at any budget you can get products rated almost close to 5/5)
2) I didnt like the looks
3) I like either super-isolating IEMs like HF5 or full-sized headphones which are only next to IEMs in isolation(though i have SR80is which are open-backed, these cant be used at work or in the cab and buses due to obvious sound leakage but if your listening environment is quite opposite then, these are bang-on! right there in sound if you could compromise little bit on amount of bass oomph and forego bass-heavy genres of music). With on-ear models what you achieve is A) cool ears since air still reaches ur ears(this is a real big problem for people like me who is pitta predominant body type and in summers just forget it!) and B) you can listen to outer noise like Phone/door bell ringing or managers yelling-out your name at work
depending on volume/isolation offered by the cans u get.
Personally i dont need such option. I just need highest fidelity & isolation at any given price point. Probably one bonus for me would be if they are easy to be driven by PMPs like Sansa Clip/shuffle etc.,
**Tell us your listening enviornment and Genre preferences/or if this is used for movies and gaming**. This will narrow down your options considerably and only then it will be a fair comparision/research. Otherwise you might like what you buy for all things else but realise it doesnt serve exact purpose you needed it for! Makes sense?
