What People Are Saying

Rated 4 out of 5 by from LG sound bar Syncs easily to the lg tv via wireless, comes on when the tv is turned on and auto adjusts to the type of sound. Easily syncs to an iPhone to play iTunes library. Great sound

Rated 4 out of 5 by from LG Soundbar The product is good and is recommended as a best buy in its price range by Which. However it is supplied without any cables (e.g. Hdmi) and the accompanying "simple manual" provides insufficient information about operating the soundbar. It is advisable to download the full manual although this runs to 38 pages if printing is required.

Rated 4 out of 5 by from Very good value Have owned this for a month now and have no problems with it. Sounds good with excellent range and base. Slightly miss the surround sound of my old system on movies, but this is so much tidier without so many wires. Would buy again

Rated 4 out of 5 by from quite good for what it is. This sound bar does the job it was designed to do, during the day I dot tend to go higher that volume 15 and at night i have to have it around 6/7 depending on the programme/film. Setup was easy it's just plug and play, I didn't need to connect the sub so cannot comment on that however there are clear instructions on how to do Overall it's a good product.
