Lenovo
 Hanging Headphone is equipped with a 10mm driver that delivers stunning
 sound for an enjoyable listening experience. It has a 5.0-volt, 500-mAh
 large-capacity battery that can last up to 12 hours. Using low-power 
micro-power technology in conjunction with chip low-power technology 
significantly increases use time. The carbon fiber composite diaphragm 
and large moving coil acoustic technology resonate under the action of 
magnetism and electricity and restore the shocking sound quality of 
high-frequency, intermediate-frequency, and low-frequency music with 
high fidelity. It is equipped with Bluetooth 5.0 chips to ensure a 
stable and fast connection. The Lenovo HE05X features IPX5 waterproof 
protection that can keep the rain and sweat far away. Its ergonomically 
designed earphones provide long-term comfort.
