"sound - i like the Grado's better for sound, to me there's a lot more detail and they're very neutral. the mdrv600's are a bit boomy and woofy."
The Sony V600 sounds much worse than the V6. The V600 is very boomy sounding and is not built as well as the V6. Years ago I bought the V600 hoping it would be better than the V6. It was much worse. My v600 broke and went in the trash. My original V6 is still going strong. The v6 has none of the boominess that the V600 has.
