I do. Completely different animal to XB500 (which I have owned as well) V6 are considerably balanced, remembering you're not going to find nearly the same bass amounts as XB500. Where it does make up for this is in overall sound quality. the mids actually have clarity and there's detail along with separation. I kept my XB500 for about one week before the 'fun bass appeal' wore off. V6 are like a breath of fresh air, much cleaner sound, bass shows decent texture, not super powerful, more pleasant with the amounts there used correctly.
The mids can sound a little grainy and treble has a few slight spikes though it's a no brainer over XB500 IF you want a detailed sound.
Very nice headphone still today!. I still think they'll sound better even with Utube than XB500 could offer.
