AfterShokz is a company that produces headphones. The main feature of their headphones is that they use bone conduction technology instead of traditional speakers. This means that the sound is transmitted through your cheekbones to your inner ear, which can be beneficial for people who are hard of hearing or have sensitive ears. AfterShokz headphones are also sweat-resistant and have a long battery life. They are a popular choice for athletes and people who are always on the go.
