I have a Hiby R6 Pro Stainless Steel Silver in excellent condition with packaging and accessories for sale. Quite the entertaining listening experience when paired with low impedance Planars (LCD-X, LCD-2CB, Hifiman Ananda, etc. [Percussive elements sound Snappy and satisfying rhythmic. The amp section drives these headphones admirably]) (especially sweet with Focal Clear, Astell & Kern Layla. Angie). Please PM me to purchase.
