I'll put in my 2 cents again on this. The XB1000 bass is very good. Controlled, detailed, goes low and has great resolution. But it does not thump like the signature XB sound so I don't know why it is considered an XB. It has high quality deep bass. Now for my other point of confusion. The mids and highs completely lag in quality behind the bass in comparison thus not making them worth $350 to my ears. Even the XB700 has better mids IMO. If the XB1000 had mids and highs to match the bass I would see these as great for $200-$250. I don't think they do. YMMV.
