Depends on which ones I guess.You guys recommend I get the PK NMDs, the PK XR1s or the plain XR1s?
I would probably say PK NMD's, though. Classic silhouette, most comfortable of the three.
For the XR1's, all mine are PK, didn't even know they made non-PK ones. Never been a fan any of the mesh stuff, so I'd pass on those. I like my PK ones a lot, though they aren't as comfortable as regular NMD's.
