I bought Sennheiser's HD6XX four years ago, and I recommended the headphones widely; the combination of sturdy build quality and phenomenal sound backed by a good value made the product the obvious choice in the sub-$300 category, and they still hold up well.
That said, there are plenty of great choices available today; Sivga's Luan is a good option at $299, and Fiio is showing that it can deliver one best-seller after another with its FT range of headsets. I tested the FT3 and FT5 when they debuted, and the budget-focused FT1 a few months ago, and all three models stand out in their own way.
