Earbuds, or in-ear headphones or earphones, are compact audio devices designed to fit snugly into the outer ear canal. They typically consist of two small speakers, or drivers, encased in plastic or silicone housings. These housings often come with soft ear tips made of silicone or foam to provide a comfortable and secure fit. The basic structure of earbuds allows them to deliver audio directly into the ear canal, bypassing the outer ear. This design helps to isolate sound and improve audio clarity, making them popular for listening to music, podcasts, audiobooks, and taking calls in various environments.
