SONY MDR-V6 monitor headphones, a model released in 1985 and never sold in Japan. I believe it's a discontinued item and has become quite rare. It's old, and signs of deterioration can be seen, so I'm listing it as a junk item just in case. Please check the photos. Since it's a used item, returns are not accepted, so please understand this before purchasing. Thank you. MDR-CD900ST / MDR-7506 / MDR-V6 ear pads / MDR-V7
