This allows users to listen to music, podcasts, or take calls without the hassle of tangled wires. They typically come with built-in controls for adjusting volume and skipping tracks. These headphones are powered by rechargeable batteries, providing hours of listening time on a single charge. Many models also feature noise-canceling capabilities, which help block out background sounds for a better audio experience.
