Real bone vibration technology
Lenovo X4 wireless earphone uses advanced bone conduction / bone vibration technology to transmit sound to the inner ear through the vibration of the cheekbone, which can prevent damage to the eardrum due to wearing the earphone for a long time, making it healthier and safer to use.
Lenovo emphasized the sound, as the high and mid-bass sound of the X4, thanks to the PromiumPitch technology, is outstanding in the field of bone-vibration earphones, thus bringing the sound quality dictated by in-ear/on-ear headphones.
