The LG Soundbar SJ4 delivers rich 300 watts of sound and a wireless subwoofer with unbeatable bass. You can use Bluetooth to connect the soundbar to your TV or other devices. When you enable Auto Music Play, music playback starts immediately when you enter the room because the SJ4 automatically detects connected devices in the vicinity. In the practical Bluetooth stand-by mode, the Soundbar will wake up as soon as audio files are transmitted and, thanks to the Auto Sound Engine, will reproduce them in a balanced and optimized manner at every volume.
The LG Soundbar SJ4 is a true eye-catcher with its minimalist slim design in every environment - perfect sound and perfect design for your living room.
Position the wireless subwoofer where you like it best and where it sounds best - without the hassle of cables.
