Well, i took the plunge and bought them in stockholm (1690 Kroner! Expensive, thats around 160/150 Euro, and the same in dollars).
But i know i got ripped of a bit, but i needed them for my flight back.
anyway, i burnt them in for 2 days before i left, just let them play a looped cd, and They sound fantastic!
I had tried the 270s, which where quite dire, and a few other models they had in the store, but the v6s had such an absolute perfect bass, it was hard, powerful, but extremely tight and controlled, I swear these headphones give the same atmosphere as being in a club (when listening to techno), the bass was phenomenol.
I tried some hip hop and electro too, in Jazz however, the highs were kind of harsh and i could tell they would tire me out a bit, Fortunetly my MD player has a small EQ (the Sony 900) so i just dropped the treble a tad, and it was perfect.
I wore them from Norrkoping to Dublin, a trip of mabey 7 hours, and they never bored me. The sound is very exciting and vivd, and its so bright and clear you really do Hear Everything in the recording. They did get a bit hot though.
I tried them from HIFI too, and they were very much the same, which is nice, because i don't really want headphones taht are too hard to drive to get the full Value for money out of them with portables.
