So guys I tried the XL today and I was pretty surprised, I didn't think these would be this good. The bass is strong and deep, but not overpowering. Actually it felt stronger than my XB500, that has a mellower, softer bass. The mids are warm but not recessed, Adele didn't sound "crystal clear" but wasn't cavernous and dark either, the highs are defined but not fatiguing to me (and I am very treble sensitive). The highs could have a little more detail but they weren't far from my X2. The comfort is great, the cups could be bigger but to me they were perfect. Build quality is stellar. I really liked them, I'll consider buying myself a pair!
