Earbuds are compact, in-ear audio devices designed for music playback, calls, and voice assistant access. Unlike traditional headphones, they sit directly in the ear canal or concha (outer ear), offering portability and often wireless connectivity via Bluetooth. Modern earbuds (like true wireless earbuds/TWS) come with charging cases and advanced features such as active noise cancellation (ANC) and touch controls.
