Headphones and Earphones Benchmarking Test Files
Still checking out the post but to anyone looking at getting a nice set of headphones, the Sennheiser 600s (mentioned in the post) can be picked up (especially used or open box) much cheaper than $500. I'd actually recommend going ahead and looking at the 650s which run $350 and under on eBay or directly from Senn during a sale. Gotta be able to have open backed headphones though, they leak a lot.
