Crossroads MylarOne X3 $57 delivered are probably better than your expensive etymotics.
Wrong again Icrim , as well as being rude.
I've heard the x3's and they don't even come close.
To the OP , I forgot to mention the Yuin PK3 , which many people on head fi think come close to the PK2.
Unlike some others, I won't speculate on something I haven't heard, but a ton of the head fi folk rave about the PK3
They are 35.00 and less now with a group buy at head fi.
I refered to the Etys as a reference, because many people at head fi consider them to be one of the best cans out there.
Of course, it is always personal preference.
I currently have the etys and
AKG K701
Yuin PK1 and PK2
And I've auditioned the Senn 650's (which I will get when I have the money

I don't think they are better than the K701, just a different slant.
The Yuins are to my ear closer to the Senns : warm and engaging with robust but accurate bass.
You can get more detailed info on head fi.
good luck on your purchase!
