Earbuds are designed with wireless connectivity, often using Bluetooth technology to provide a cable-free connection to devices. Many models include noise cancellation, either active or passive, to help block out unwanted external sounds for an immersive listening experience. Touch-sensitive controls are a common feature, allowing users to easily manage music playback, volume, and calls without needing to reach for their devices. Earbuds also offer long battery life, with some including fast charging options for quick top-ups.
