This is a Shinken Zemi (Benesse) elementary school 5th grade educational material. I opened it for the photos, but it's new and unused. I tested it with an iPad 9th generation to confirm it works, and it worked without any problems. It can be folded. The length of the headband can be adjusted. I will ship it without the box. The diameter of the ear pads is about 7cm. It might be a bit small for adults. - Colors: Blue, Black - Type: Wired headphones - Ear pads: Synthetic leather Thank you for looking. #Headphones
