Pros : extremely articulate, quick response. No mud.
Cons : fairly harsh, not sweet at all. All that focus gives a fairly flat, sterile sound.
I have a high end set of headphones, a tom Anderson hn3 plus pup and extensively played the Celestion century 80 speaker. All feature neo magnets and the cold, icy sounding high end character is unmistakable and inherent to all. That's the neo sound.
