Wireless earphones typically use Bluetooth technology to connect to your devices, allowing you to listen to audio wirelessly.
Dual-earphone refers to a design where you have separate earbuds for each ear, providing stereo sound and a more immersive listening experience.
Wireless earphones are often compact and lightweight, making them convenient to carry around and use on the go.
Battery life is an important consideration for wireless earphones. The specific battery life will vary depending on the model, but they are usually designed to provide several hours of continuous playback before needing to be recharged.
