Headphones and earbuds are personal audio devices that allow individuals to listen to music, podcasts, and other audio content without disturbing those around them. They come in a variety of designs, including wireless and wired models, noise-canceling options, and sport-specific designs. Headphones are typically worn over the ears, while earbuds sit inside the ear canal. They have become increasingly popular in recent years due to the rise of portable music players and smartphones. They provide a convenient and immersive listening experience for individuals on-the-go, whether they're commuting to work or working out at the gym.
