These headphones have a cute design and come with a case and charging cord. I bought them as a fashion item in addition to listening to music, but I haven't used them in a while, so I'm selling them. They can be used both wirelessly and wired. They are also foldable and easy to carry around. The main unit has three buttons: the bottom one is the power button, and the top two are for volume control. Accessories include a hard case, a connection cord for wired use, a charging cord, and a pouch for the cords. The box and instruction manual have been discarded. The condition is relatively clean, and there is no hydrolysis on the ear pads or head portion. There is a black stain on the left ear pad in the fifth image. Because of the white and silver combined design, dirt is easily visible, so please let me know if you would like additional images. I will pack them carefully, but I cannot be responsible for damage during shipping. I may use recycled materials for packaging. I may change the shipping method from Rakuraku to Yuuyu after purchase. To prevent trouble, I do not offer exclusive listings or holds. To prevent product substitution, cancellations and returns are not accepted after shipping. I have described small scratches and scuffs in detail in the images as much as possible, but please purchase after judging based on them, as they have been in someone's possession. If you have any concerns, please ask questions, and I will answer to the best of my memory, so please consider after resolving them.
