    Overview

    The LG SJ4 is a premium soundbar offering that’s designed to take your home theatre experience to the next level. Hi-Res Audio gives this soundbar the guts needed to create a remarkable audio experience and with a wireless subwoofer, you’ll have great bass to go along with it.

    With Bluetooth connectivity, it’s a breeze to share your favourite music wirelessly from your smartphone to this soundbar. Wired and wireless connectivity built-in, makes pairing this soundbar with your TV easy.
    Music Streaming

    Wireless connectivity through Bluetooth makes sharing your favourite music from your smartphone or tablet a breeze. If Bluetooth isn’t an option, you can still share your music through Wi-Fi.

    Hi-Res Audio

    With Hi-Res Audio technology built-in, you’ll be able to easily play ultra-high quality music without having to compress audio. Working alongside the high-fidelity speakers and a Subwoofer, you’ll hear every beat and breath in glorious clarity.

    LG Sound Sync

    Take the guesswork out of pairing this Soundbar with your LG TV. Designed to wirelessly sync audio from your TV to the Soundbar using Bluetooth, this Soundbar is easy to setup. Don’t worry if you don’t have an LG TV, this Soundbar still has wired and wireless connection options for other TVs.

    Adaptive Sound Control

    Whether you’re watching sports, the news or listening to music, this LG Soundbar automatically detects what’s playing and then adapts the audio output to highlight what’s important. In reality, this means that if you’re watching dialogue-heavy content, you’ll hear speech clearer and if you’re listening to music the focus will be on bass.

    A terrific boost
    We have connected this LG soundbar to our TV in the living room. It gives a terrific boost to the sound experience especially when watching films. We did experience a slight echo problem with the TV and the soundbar slightly out of phase. The solution was to turn the volume on the TV down to zero, and then just use the soundbar volume control.
