There are only minor scratches, and I think it's relatively clean. The bushing at the cable entry point to the housing had a crack, so it has been glued. The ear pads were starting to show wear, so they have been replaced with new compatible ones. Well, as for the appearance, it's based on my personal subjective opinion, and there may be other scratches that I haven't noticed, so ultimately, I will leave the judgment to you based on the images. Thank you for viewing.
