Rated 4.5 out of 5 by 237 reviewers.
Rated 5 out of 5 by Great sound, great expected. I bought a similar sound bar for my son about a year ago and was surprised by the quality sound it produced in conjunction with his television. So I asked for this one as a gift this past Christmas. Set up was quick and easy. I am an avid sports fan and movie buff...and this sound bar engulfs you in all of the rich sounds. I could not be more pleased! And the blue-tooth feature makes listening to stereo music from my smartphone a natural choice. April 12, 2014
Rated 4 out of 5 by amazing sound Ive had this soundbar for awhile and its the best thing ever. High quality sound for movies, gaming, and music. I use it everyday March 25, 2014
Rated 5 out of 5 by LG Sound Bar Is Great! My LG sound bar is now 1 year old and has served me very well. The NB3520A was easy to set up and it adds an significant dimension of sound and setting options. It works perfectly with my LG 55in 7600 series 3D TV. I prefer it when I can have matching brands of components and LG offers that plus I know the quality is going to be outstanding! December 8, 2013
Rated 5 out of 5 by great sound I have been waiting for this sound for years; now I can truly enjoy all programs. August 7, 2013
Rated 5 out of 5 by I like it I bought this based upon all the positive reviews I read. I'm happy with it, but it does have a few shortcomings. I'm disappointed that the volume level on the woofer only goes to 6. If it could go to 8, it would be better. Set up was easy. I now have to have 4 remotes. One for cable tv, one for LG 55" led 3D TV, one for LG BluRay player, and one for the LG sound bar. Wish they could all be combined into one, but that would be asking alot. It has enough bass for me, and the sound is great. Separation of surround sound is not as good as I'd like it to be, but it's ok. I also don't like it that I have to go to the front of the sound bar to see what it says. Wish it could be displayed somehow on the TV screen. Otherwise, I like it. It looks good. I have the sound bar sitting on top of a cabinet which is 24 inches off the floor. The woofer is 18 feet away in an opposite corner, and it has no trouble syncing with the main unit via wireless.

Rated 5 out of 5 by Great sound quality Bought this as an open box item and saved quite a bit of Money. Honestly, I didn't want to get a sound bar because I though the Telly could submit enough sound, however, I have an open concept living room and needed the sound bar to submit enough sound. Def worth the money. I feel as though I'm at the movies everytime I turn the tv on. May 25, 2013
Rated 5 out of 5 by game changer replaced my surround sound with this soundbar after much research, great sound, tv speech is a lot clearer than it was and explosions don't knock you off your seat because you have cranked up the volume to try and hear what theyr'e saying. May 19, 2013
Rated 5 out of 5 by LG Soundbar + Sub I got this to go with my LG 47" Smart TV for a little better sound. This sound bar will not disappoint anyone looking for much more sound, while not breaking the pocket book or taking up much space. It is also very easy to setup. The sub provides ample base, and the bar itself provides more than enough sound for movies and music. Being Bluetooth, I often connect my smartphone to it to listen to music. May 16, 2013
