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, making them 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 part. There is a black stain on the left ear pad in the fifth image. Because the design is a combination of white and silver, 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 Yu-Yu after purchase. To prevent trouble, I do not offer dedicated listings or holds. To prevent product substitution, cancellations and returns are not accepted after shipping. I have described small scratches and scuffs in as much detail as possible in the images, but please purchase them after making your own judgment, as they have been in someone's possession. If you have any concerns, please ask questions, and I will answer them to the best of my memory, so please consider them after resolving your concerns.
