This is the MDR-W5, a high-end dynamic headphone for Sony's early Walkman models. It's a stylish model with high sound quality. The number of existing units is small, and those that still function are extremely valuable! Prior to listing, I have cleaned and maintained it, so you can enjoy clear sound quality and use it for a long time to come. Please experience the quality of the sound. Dust removal, unit and diaphragm inspection, cleaning, and plug polishing. Ear pads replaced with new yellow ones. This is a Showa-era machine released about 45 years ago, but it can be used comfortably as it was back then thanks to the refresh. I would like to sell it to someone who will cherish it. This is a private sale of used electronics (antique). Please refrain from purchasing if you require after-sales service or are overly concerned about minor details. Those individuals should purchase new products. I have no experience with failures caused by shipping, but in the unlikely event of a problem upon delivery, please contact me before leaving a review. I will definitely address the issue, so please rest assured. TPS-L2 WM-2 WM-DD WM-D6 WM-D6C MDR-4L1S MDR-3L2 Buyee ZenMarket From Japan Support for the Noto Peninsula Earthquake - Partial Donation
