WH-1000XM4 Black Retail Price: ¥47,300 I purchased and used these when they were first released, but I'm selling them now as I haven't been using them much. I'd say the condition is good, as I only used them a few times a year. *Please understand that these are used items, so only purchase if you are comfortable with that.
