These noise-canceling headphones are compact and foldable, making them convenient to carry. They reduce ambient noise by up to 95%. They can also be used as regular headphones when the power is off, so you can still enjoy your music even if the battery runs out. Purchased new in April 2025, they are in excellent condition, having been used only once. Includes the instruction manual, an airplane adapter, and a third-party EVA case (Geekria brand, with a pouch).
