Please read the product description carefully and purchase only if you understand and agree. This is the latest model of the "DT 1770 PRO MK II". It was purchased from e☆イヤホン in March 2025. The receipt and warranty are not included, but the proof of purchase document shown in the photo is included. ※ The ID is masked with a mosaic to prevent misuse. A VIABLUE EPC-2 Silver 3.5mm 1m cable (8000 yen) is included. I mainly use open-back headphones, so I used these only about 2 times a month, for 1-2 hours each time. The ear pads other than the ones attached to the main unit in the photo have only been tried on. There are no issues with the sound. As this is a used item, there are some signs of use such as minor scratches and scuffs. Please refrain from purchasing if you are sensitive to these details or if you are looking for a product in new condition. - Brand: beyerdynamic - Model Name: DT 1770 PRO MKII - Color: Black - Country of Manufacture: Germany - Type: Studio Headphones Closed-back monitor headphones
