Hi,
I just listened to them at my local hifi store. Man. I couldn't stop listening to them. I went through my whole testing playlist over and over again. They are amazing. I listened to them unamped from an iphone5 and don't want to now how good they will sound with my home and office setup. These are for sure my next headphones.
They are versatile, detailed and fun. I couldn't find a single song I didn't like with them. After having tested that day the new Harman Kardon (arghh), Sennheiser Momentum and Amperior, the Focal Spirit One (really good), I thought I found my favorite with the Focal One. But no, after listening to the PSB M4U2 1 and 2 I know now that I really want these. They are so good.
So it seems my HD598, HD239 and my Ultrasone Pro 750 won't get so much head time anymore.
By the way, as open headphones go, the Yamaha HPH-200 is an absolutely bargain, aft having it for two weeks I can't stop listening to it.
Now I just need to convince myself fully that I NEED another pair of headphones
Cheers,
K
