What People Are Saying

Rated 1 out of 5 by from Subwoofer lasted less than two years Bought this in May 2015. For the last two months the bass has been cutting out. I suspected it may have been poor bluetooth reception. When I got home from a four-day trip, I noticed it died. No light(s), no sound; nothing. $270 gone.

Rated 5 out of 5 by from Great product. I bought this sound bar within the last year. It was an easy setup and I have no problem operating it. Settings are easy to adjust and has great sound. I would recommend this LG product to anyone.

Rated 4 out of 5 by from GREAT sound, with one annoying feature Really liking this sound bar! Set-up was a breeze, and the wireless sub and main unit paired automatically within seconds. The unit detected the optical cable right away, and I programmed my Rogers remote to control the sound bar very easily. I have one complaint. The LCD on the front of the sound bar is VERY bright. There IS a way to turn this off, but it continually reverts to the previous setting, meaning every time you turn the sound bar on and off, the bright LCD is back on. I'd like to have an option to turn this off permanently, and only have it light up when a button is pushed.

Rated 5 out of 5 by from Great! Easy to setup. I used the optical cable to connect my 55" LG 4K tv and used bluetooth to connect my iPhone. No issues at all. Sound is great!

Rated 5 out of 5 by from This Sound Bar is Great I got this sound bar to go with my LG High DEF 4 K TV because I did not like the sound of the TV alone. After receiving and installing this sound bar witch was so easy 1 optical cable from TV to sound bar and that was it, perfect sound and sync on LG optic out. Could not be happier. Thanks LG for this match.

Rated 5 out of 5 by from Great sound and lots of features I spent some time reviewing various Sound Bars on line prior to my purchase of the LG LAS551H. Its good reviews and the fact I have a LG 55LN5750 LED Smart TV, which could be paired to this Sound Bar wirelessly, finally sold me on it. I ordered one online through Best Buy who had it on sale at the time. Once it arrived it only took a few minutes to hook up the unit. It paired up wirelessly with my LG TV without any issues when I set the TV's sound output to Sound Sync. Once it’s was set up, it pairs without issue as soon as the TV is put on. In addition, the wireless Sub paired up with no problems as well. I also connected my Blu-ray player by HDMI cable through the sound bars “HDMI ARC” to the TV’s “HDMI ARC In”, without issue. Because the sound bar also has an “Optical In” connection I hooked up from my Satellite Box to the Bar to play my favorite radio music, that way I don't need to have the TV on to listen to it. The Bar switches automatically to whatever input is active at the time as intended. I’m no audiophile, but I can positively say the sound produced by this sound bar is as good as the Stereo Receiver it replaced if not better. A couple more plusses are it’s also a good looking unit and appears to be well constructed. Overall I’m quite satisfied with my LG LAS551H Sound Bar so far and its functionality. At the sale price it was a great value and does exactly what I wanted it to. I’d recommend this LG product to anyone looking for a quality Sound Bar, and Sub woofer to use with their system.
