I just pulled the trigger on a pair of HE-500's, should be here on Monday. Just one more set of cans, the pile is setting high, I was looking at the Sennheiser HD800's as I already have a pair of HD600's, my favorites. I decided to try a different technology and since I like extended bass, I think these will make me very happy, although I may have to get used to wearing a brick on top of my head
How would you guys compare the sound profile of the HE-500's to the Sennheiser HD600 and HD650 cans? Describe the differences in terms of bass, mids and treble.
