What People Are Saying

Rated 5 out of 5 by from Works great! Mine came with free surround kit! Bought this last week and it came with the surround kit for free. Set up was a breeze and the sound is excellent! I do not have issues with sound cutting off. For the price I paid, it is well worth it.

Rated 5 out of 5 by from SIMPLE AND ELEGANT I understand that people are having issues with the sound cutting out. When i bought this I also bought the SPJ4-S wireless surround kit. Immediately paired to my new 55C6P OLED television and the surrounds. Guess what, no glitches or cut out issues. It also has a rich and full sound. I think there is supposed to be an update for those that buy this as a stand alone unit, but I thing LG should sell this complete with the surround speaker kit and avoid the glitch.

Rated 1 out of 5 by from Sorry I bought it !!! I bought this 3 days ago , sounded great at first , within an hour ,the sound stopped for a second . Later the stoppage was more like 2 seconds. Very very annoying . We live in a small one bedroom condo, we do not need surround sound so no need to buy it. Which I'm told would fix this annoyance. I'm returning this unit , probably will get another brand.

Rated 1 out of 5 by from Disappointed Looked forward to this product arrival. Which only added to my disappointment to upon set up. All synced well with my LG TV. But then, to my chagrin, the sound cut out every so often. This totally turned my audio video experience in a negative direction. I have read about an update on this site to cure this problem but have found nothing. Returned product and I'm awaiting replacement.

Rated 2 out of 5 by from Audio is good. One big problem though! I bought this last week and loved it, at first anyway. Every few seconds or sometimes minutes the audio cuts off and back on. VERY ANNOYING. Seems I'm not the only one having this problem either. Will be returning it tomorrow if I can't get a straightforward answer on how to fix this problem.

Rated 5 out of 5 by from All around amazing! Just purchased this product today with the surround sound speakers (SPJ4-S). Took all of 10minutes to plug in and enjoy. Everything automatically connected to each other flawlessly. Subwoofer is more than what I expected for the price. Easily switches between Bluetooth and the TV. Easy 5 stars on this one!
