Sony 2.1ch Soundbar with – 330W Output

Upgrade your TV sound with the Sony HT-S400, a 2.1-channel soundbar paired with a powerful wireless subwoofer. Delivering a 330W total power output through a Digital S-Master amplifier, it adds depth, clarity, and bass that built-in TV speakers simply can't match—bringing movies, series, sport, and music to life in your living room.

Wireless Subwoofer

S-Force PRO virtual surround technology creates a wider, more enveloping soundstage from a single bar, helping place effects around your viewing position without the need for rear speakers. Dolby Digital decoding supports cinematic audio from compatible broadcasts, discs, and streaming sources, with Dolby Dual mono and LPCM 2ch also supported over HDMI and optical connections.

S-Force PRO Surround & Dolby Digital

The wireless subwoofer adds rich, room-filling bass and connects without a cable running across your floor—making placement far more flexible. Its 192 × 387 × 400 mm cabinet houses a substantial driver, and the bar itself measures a slim 900 × 64 × 88 mm, sitting neatly beneath most TVs or wall-mountable with compatible brackets. Everyday listening is well catered for with Night Mode, which compresses dynamic range so you can watch late-night without disturbing others, and Voice Mode, which lifts dialogue clarity for news, dramas, and films. A range of sound fields and sound effects let you tailor audio to the content.

Simple Wireless Music Streaming

TV Wireless connection lets compatible Sony BRAVIA TVs link to the soundbar wirelessly, reducing cable clutter, and Bluetooth 5.0 (SBC) allows simple wireless music streaming from your phone or tablet. Wired connectivity includes HDMI ARC output and optical audio input, plus a USB Type-A port for firmware updates only. Power consumption is modest at approximately 35W for the bar and 20W for the subwoofer, with both drawing just 0.5W in standby.
