KNS8400 sounds surprisingly close to K70x. The cable bears too much noise and needs replacing. I haven't heard the 6400, which uses the same cable.
SRH440 has an uncomfortable headband. It has no bass and hot highs, even with mods. Supposedly, every third pair is "bass heavy" (yeah, right).
@Claritas Thank you! The more I look into headphones, the more big red SAVE MONEY FOR HD600 flashes in front of my face hahaha.
You're welcome. The best cheaper closed phone for me was XPT100 / HM5 with thick felt in front of the driver. But it doesn't compete with HD6x0 or good Fostex mods. Best luck!
