Glad that I'm not the only one who hears that "bloom" in the lower mid region which you refer as syrupy. It's pleasant sure but it's not present in the original recording.
That being said, I definitely favor the HE-500 over HE-6 but I still think that $899 is a bit overpriced for these.
You're definitely not the only one who hears that mid-bass. That was maybe my only actual grievance with the HE-500.
When you say that you think the HE-500 are overpriced is it in comparison to other headphones of similar quality, or are you saying that you think $900 is too much to pay for a pair of headphones?
