LG 2.1ch Soundbar with Subwoofer | SJ4 is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Great Sound! Bought about a month ago to go with my new LG 4k tv, its great play around with the tv setting namely DTV settings etc once connected with HDMI ARC (not optical for better sound quality) and this bar really packs a punch, even juts plugging it ina nd using it you can hear a difference, for best results play with tv settings if you setup has them settings/functions! well worth it great product looks/sounds great easy to use, (HDMI ARC or Optical connections) not hard to setup at all! Sub has a power cable of course but other then that no other wires, only wires from tv are to sound bar (HDMI v2 Lead) and power lead for bar it self! sits very nice infront of TV aswell! sub get some bass to it when you turn it all up aswell, sounds immense on games!

Rated 5 out of 5 by from Great sound I bought this in time for Christmas. It was a little tricky to set up but once I did the difference in sound especially on action movies is amazing & the unit is great value. I also have it set up as a Bluetooth speaker for my iPhone & iPad.

Rated 5 out of 5 by from Truly staggering sound quality For such a small package this soundbar is crazy loud. The quality of the sound is great, value for money is even better. It has more inputs than some that are double the cost. I really cant recommend this soumdbar highly enough.
