We all love getting stuck into a good movie. This LG USC9S soundbar uses Dolby Atmos and DTS:X to immerse you in a dome of 3D surround sound for that movie theatre experience in your front room. Every footstep, creaky floorboard and spine-chilling scream will have you hiding behind the sofa. It has 7 channels (3.1.3) of high-power audio, including a centre up-firing speaker and a powerful subwoofer, so you'll hear every tiny little detail. Better still, there's no pesky wires to get in the way. And with the Triple AI Sound Optimiser, the audio is fine-tuned to perfection for your specific space, whatever you're watching - sports, movies and TV shows will sound epic.

Good to know

- It's loaded with Meridian Sound technology, so you can binge your favourite shows in high-resolution audio
- WOW Orchestra uses both the soundbar and the speakers in your TV, so the sound hits you from all angles
- Pair your soundbar with your compatible LG TV and control it using your TV remote – that's one less thing to find batteries for
- Can't find the remote? Control your soundbar using your voice with a compatible Google or Amazon Alexa smart speaker
- Its modern design pairs perfectly with LG OLED C Series TVs for a seamless all-in-one look
