Headphone [Damaged Item] Pierre AVIOT× True Nakano Wireless Earphones TE-BD21f-pnk Special Edition

Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Product explanation ■ This item says "damaged item (puff with built-in earphones, damage due to rubbing on the switch part and decoration peeling. Semi hard case zipper is damaged)". Please understand it in advance.
This is a collaboration model with special tuning supervised by Pierre Nakano, the drummer of "Rinto Shigure".
Fully wireless earphones TE-BD21f equipped with the world's first hybrid triple driver.
This high-end model faithfully reflects the (extremely high-level) advice of Pierre Nakano, who is also known as an earphone-mania.
Without a sense of distortion, it has a high sound range that extends to any length, a high middle sound range where the vocals come in front of you, and a rich low sound range that faithfully conveys the sound of a bass drum.
This is a superb item that can feel the passion of a professional musician.
