This is a new open-back planar magnetic wired headphone from Sendy Audio (a high-end brand derived from SIVGA). Currently sold on Amazon and other retailers for around 80,000 yen. *Photos of my own are included as a reference for the contents. The item for sale is a new, unopened product. The wooden housing may have slight variations in appearance. This was a campaign prize. I am selling it because I already own the same model. No smoking, no pets. *Returns are not accepted to prevent product substitution. In the event of initial defects, please contact the manufacturer or the domestic distributor. I can also open the package and check the operation before shipping. If you wish, please contact me after purchase.
