A soundbar is a long, slim speaker system designed to enhance audio quality for televisions and other devices. It typically contains multiple speakers within a single enclosure, allowing for a more immersive sound experience compared to standard TV speakers. Soundbars can connect to devices via Bluetooth, HDMI, or optical cables, making them versatile for various setups. Many soundbars also come with built-in features like virtual surround sound and subwoofers, which improve bass response. They are popular for home theaters and gaming setups, providing a compact solution for better audio without the need for multiple speakers scattered around the room.
