Headphones are a type of audio device worn over or in the ears, designed to deliver sound directly to the listener. They come in various styles, including over-ear, on-ear, and in-ear models, each offering different levels of comfort, sound quality, and noise isolation. Headphones are commonly used for listening to music, watching videos, making phone calls, gaming, and participating in virtual meetings. Many modern headphones feature advanced technologies such as Bluetooth connectivity, noise cancellation, and touch controls. Wireless headphones, in particular, offer added convenience and freedom of movement. Over-ear headphones provide rich, immersive sound and are often preferred for high-quality audio experiences, while in-ear headphones (or earbuds) are compact and ideal for portability. Headphones may also include built-in microphones for hands-free communication, as well as adjustable sound settings, making them versatile for various audio needs.
