Used? GROSS. I wouldn't pay more than $2 bucks for Dan Clark's Dandruff Dandelion; or Focal's Fenestrated Fungus Factory; that's an audacious amount for Audeze's Loosely Crusted Dermatitis, or even the Melon Mushroom 500s; no deal on Audio Technica's Seborrhoeic Scab Sakura Blossom; ditto on the dome detritus Dirty Dianas, as I'd be abandoning them to the Abyss. GL. Yuck.
