These are the "Wireless Piyahon 2" wireless earbuds, supervised by Pierre Nakano. 【Condition】 Left, right, and case all function normally, but the case doesn't close, so it's secured with a hair tie. Charging works fine. I don't have expert knowledge, so I can't tell how much they've degraded. I also don't know how much battery life is left, so I'm selling them as junk. I will clean them as much as possible and wipe them down with消毒用アルコール before shipping. 【Included Items】 Case Earbud units Instruction manual 【Product Information】 Original price: Around 10,000 yen In-ear type True wireless Noise canceling
