These are wireless earphones supervised by Pierre Nakano. He is famous as the drummer of Ling tosite sigure, among other things. They are a collaboration product with the popular anime "PSYCHO-PASS," and when connected, you'll hear voices of the Dominator, Shinya Kogami, and Akane Tsunemori. Frankly, the Dominator is overwhelmingly cool, so I recommend it. And the biggest drawbacks are the noticeable scratches, the missing ear pads (spare), and the left panel, which allows you to hear a special voice by long-pressing, is broken. That's right. The Dominator only speaks when connecting or when the battery is low. He's become shy. Other than that, the operation has been confirmed, so please rest assured. If anything happens, please contact me immediately. I don't want to be held legally responsible. The price is set high, but if you absolutely, absolutely! want them, you can negotiate a price reduction. I will lower the price while crying. Thank you very much.
