Hi,
This is my first post here and I'm very happy to join to such a great community.
I want to buy a pair of headphone and upgrade from my AKG K240S. Hifiman HE-400 grabs my attention but when I went to head-direct I found out that it has another model that is only 449 $. Can anyone tell me what is the difference between these two? and which one is a better choice?
