    Overview

    The Sony HT-S400 2.1 Channel Soundbar delivers an effortless way to elevate your home entertainment with rich, immersive audio. Designed to bring movies, TV shows, and music to life, this streamlined system combines a powerful wireless subwoofer with advanced speaker technology for clear dialogue and deep, impactful bass.

    The HT-S400 produces 330 watts of total output power, filling your room with cinematic sound. Sony’s S-Force PRO Front Surround technology emulates a multi-speaker surround sound experience using just the front speakers, creating a spacious, enveloping sound field without clutter. The built-in X-Balanced Speaker Units feature a unique rectangular shape to maximise diaphragm area, reduce distortion, and improve clarity, while the Separated Notch Edge enhances vertical amplitude symmetry for more natural vocals and sound effects.

    The wireless subwoofer’s large 160mm speaker unit delivers richer, more resonant bass, perfect for action-packed movies and dynamic music tracks. With HDMI ARC and optical connections, setup is quick and simple, while Bluetooth connectivity makes it easy to stream music directly from your smartphone or tablet.

    Convenient controls and an intuitive OLED display window allow you to adjust settings effortlessly, including dedicated Voice and Night modes that adapt sound to suit any time of day. Compatible with select Sony BRAVIA TVs, the HT-S400 also supports wireless audio transmission and integrated on-screen controls for a seamless viewing experience. Stylish and wall-mountable, this soundbar blends effortlessly into any living space while offering powerful performance that elevates every moment.
    S-Force PRO Front Surround

    Sony’s virtual surround sound technology delivers expansive audio using only front speakers. Experience an enveloping soundstage that places you right in the centre of your movies, all without additional rear speakers.

    Powerful Wireless Subwoofer

    Enjoy deep, resonant bass that enhances every soundtrack. The large 160mm wireless subwoofer produces rich low-end sound while keeping your entertainment space free of cables and clutter.

    X-Balanced Speaker Unit

    Unique rectangular drivers maximise diaphragm area for punchy bass and clearer vocals. Reduced distortion ensures that dialogue and effects remain crisp and detailed, even at higher volumes.

    Voice and Night Modes

    Tailor your listening experience with dedicated sound modes. Voice mode emphasises dialogue for clarity, while Night mode reduces volume spikes, making late-night viewing more comfortable without sacrificing detail.

    East setup
    My partner suggested upgrading. So happy - sound quality is brilliant.

    Amazing sound
    I was hoping for a good sound from my first soundbar and I’m amazed at just how good the sound quality actually is. Easy to set up, looks great on the wall and the powerful sound produced is clear and balanced. The convenience of a wireless subwoofer with deep rounded bass completes the package.
