Shokz bone conduction headphones transmit sound through the cheekbones instead of into the ear, allowing you to hear sounds and calls while staying aware of your surroundings. They are lightweight and comfortable for long periods of use, making them suitable for work, field sites, and sports. The microphone is good for calls and meetings, but the sound quality is lower than traditional in-ear headphones. Suitable for those who have many calls and excellent ambient sound isolation.
