Purchased from Soundhouse in July 2023. Used only a few times. There are a few scuffs on the headband, but I've uploaded photos, so please take a look. The ear pads are very clean with no signs of use. I also purchased spare ear pads separately. These are unused and still in their original packaging. Accessories include a stereo conversion plug, an AKG genuine 3.0m cable, and the original box. The original cable was a coiled cable, but I replaced it with a straight cable because it was difficult to use. With a sound pressure level of 109, it's one of the easier models to drive in the company's product lineup, I think. It gives the impression of being honest in both appearance and sound. Please refer to the photos of the original box for detailed specifications. 【 Product 】 AKG closed-back studio headphones, ideal for monitoring and mixing. - Model Name: K553 MKII - Type: Closed-back studio headphones - Left/Right Indicator: R/L indicator - Brand: AKG - Applications: Monitoring, mixing, mastering
