Doug Paratore of SoundStage gets down with comparing Sennheiser's famous HD 600 with the $549 HD 650. While a little late to the party, Doug gives a nice, snappy summary on the HD 650s, how they differ from the 600s and more. In case you don't know, the 650s are considered by a great many to be the best headphones in the world. Paired with a great headphone amp, the Sennheisers can compete with $10k stereo systems. Of course, why leave a good thing alone when you can replace the cabling and cover your cans in wood?
