Extended battery life, say goodbye to battery anxiety. Battery life lasts over 8 hours.Foldable and portable, compact storage. The headphones support 90 rotation and a foldable design, reducing the volume by half when folded. A portable storage bag is included, making it easy to fit into a backpack or handbag, ideal for commuting or travel without taking up space. Physical noise cancellation + ambient sound mode. The ear cups' sealed design inherently provides physical noise cancellation (blocking out 30% of ambient noise); holding down the function button switches to ambient sound mode, allowing you to hear surrounding sounds (such as subway announcements or colleagues speaking) without removing the headphones, balancing immersion and safety. Ergonomic headband design for all-day comfort. The ear cups are made of protein leather material, with slow-rebound memory foam padding inside, conforming to the ear contour without causing pressure. Even after wearing them continuously for over 3 hours, your ears will not feel sore or swollen.
