Very very bad experience with them. Actually last comment i made was just about them.
Got two of them, but both broke (thankfully got refund) and while i like good amount of quality bass(hint my Denons) the turbines had painful highs and they where first headphones for me that did not fit to my ears that great, one reason was the weight. Though they come with very good 6 different tips, even if there was not one perfect for me and there is still quite big of a fan base around them.
They need at least ~70hrs of burn to smoothen them.

In head-fi those special edition turbines with better wires and insides are ranked very high, but those different editions where at least last year quite expensive at around 150-250 euros.
