## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing sound
*by S***Y on 4 August 2026*

Brilliant surround and so easy to set up, would definitely recommend

### ⭐⭐⭐⭐⭐ Great Product
*by T***A on 23 August 2026*

Just what was required also great sound

### ⭐⭐⭐⭐ Fair price for an easy to set up, good bass and surround but poor mid range sound bar.
*by G***H on 3 March 2025*

This is a nice quality item for the price, although it wasn't obvious that the rear speakers needed connecting together with a wire (included in the box and extremely long), although the subwoofer is wireless. Setup was simple, and although the included remote control responds well, it's easier to set up and customise via the LG Thinq smartphone app. If connected via HDMI/ARC to an LG smart TV, it can be turned on and off and volume can be changed via the TV remote, but there's around a 10 second delay and depending on the TV sound settings, some silence when starting up. I bought an optical cable and have it connected to that instead so that it's controlled separately from the TV (avoiding the delay). I've awarded 4 stars because I am a little disappointed with the lack of "forward facing" sound from the soundbar itself, and tone only allows for bass, mid and treble rather than a full EQ range, but the subwoofer and surround speakers sound awesome. Good overall.
