・This is AKG's flagship model. It's a high-end model that pursues the exquisite detail and acoustic resonance unique to this manufacturer to the extreme, and it delivers indescribably beautiful sound, especially with classical music. ・I purchased it new several years ago and used it occasionally, but I found it to be a bit too focused on the high frequencies for my taste. I preferred the lower-end K712, so I decided to keep that one and sell this unit. ・I haven't used it much, so I think it's in pretty good condition. However, there are some minor scratches and blemishes from use, so it's not quite like new. Please understand this point before purchasing. ・The items included are the main unit, original box, headphone stand, cable, and instruction manual.
