Sennheiser HD518 Open-Back Headphones

This is a Sennheiser HD518 open-back headphone.I purchased it new and used it for bass practice and listening to music. I have stored it at home in its box for several years. Although time has passed, I can listen to music without any problems with the sound quality.I really liked the sound, but I no longer have the opportunity to use headphones, so I am selling them.As shown in the sixth photo, there are slight scratches.They are barely noticeable.The condition of the ear pads is not good. They were fine before storage, but the cushioning has thinned out after storage.New ear pads are sold on Rakuten and other sites for around 2000 yen, so I recommend replacing them.* Although it functions without problems on my end, please understand that this is a used item before purchasing.The warranty has expired, but the warranty card is also included.Type, Wearing Style: Over-EarConnection Type: WiredStructure: Open-Back (Open-Air)Drive System: DynamicPlug Shape: Standard Plug/Mini PlugFrequency Response: 14～26,000HzImpedance: 50ΩSound Pressure Level: 108dBWeight: Approximately 240g (excluding cable weight)Accessories: 3.5mm conversion adapter faultless for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
