Bpandbass was fortunate to be able to demo the MDR R10 headphones from Sony for a short 3 days. These are considered to be one of the top 5 headphones ever produced. Many consider them just behind the Sennhieser Orpheus. Check out the review over on Head-Fi.
Pros: Beautiful, pure and tonally perfect midrange; ZERO grain and brightness/sibilance; easy to drive; exquisitely made; supremely comfortable
Cons: Not the last word in perceived tonal detail or bass energy;
