Very Cool Systemha

RichTx6 7/1/2018

I picked this unit up at BestBuy on a closeout deal and after I got it home I had a few issues hooking it up and pairing it together because it didnt come with the owners manual. Got on the LG website and downloaded the manual and hooked it right up. Sounds Great and really like the fact that you can separate the speakers which sounds much more like a normal stereo. Really like the portable bluetooth set up the remote that controls bass treble and woofer. Just a neat unit.

Speakers randomly disconnect from each other

Good design - great sound

dolfin65 6/16/2018

I bought this product as a gift. The sound quality is great. Really enjoy watching movies now with this sound bar. The reason why Im giving this review good vs. excellent is due to the Bluetooth compatibility. Its great I can play my music on my computer through the sound bar however every time I turn on my wireless headphones it turns off the sound on the TV. So if someone is watching a movie and then someone else wants to list to music from their computer with the wireless headset the sound for the movie stops. Im unable to find a solution to this problem. Other than that one little issue Im very pleased with the product. I really like how the speakers can be separated on each side of the TV or take one in another room. Great feature.

Just what we needed

Jimmc 5/15/2018

Weve had this for a month and are pleased with the sound. We are not audiophiles and are not interested in decibels and technical details. Our flat screen has bad sound some because of the TV and much because of the uneven sound being broadcast. We had a couple soundbars before and couldnt get them to function properly. All the reviews indicated a subwoofer was a necessity. We dont use ours because all we detect is booming bass. The split speaker is a nice touch as well. I guess our only complaint is that the power shuts off with the TV and has to be turned on using a separate remote.

Barely Flexible Design

Petri 5/1/2018

I needed a sound unit that I could route my HDMI cable into and out by my projector. I thought these would work great since I could have a rear speaker and a front speaker or split left and right speakers without needing to run wires around my couches. Turns out their flexible design requires the main unit to sit either at the front of the room or on the left hand side since the right speaker is the portable one. My projector sits on the left of my seating arrangement meaning that I either have my sound scape reversed from front to back or left to right. There should have been a way to flip the sound between the two speakers so that you can choose where they sit in your room.

Take reviews with a grain of salt

Cowboy Ed 4/19/2018

We just bought a new LG TV and LG sound bar. Had Geek Squad install it all for a hundred bucks. Best money I ever spent We were very unhappy with the sound bar. Read the quick start instructions and were ready to toss it all However after punching too many buttons and screwing things up we settled down read the full operating manual we got off the computer and walla. This is the very BEST SOUND BAR out there. It is excellent and we love it and highly recommend it to all who have a little patience. Reviews dont always tell the FULL story.

Interesting idea bad execution

samsimeon 4/13/2018

I loved the idea of this sound bar and I tried to look past the flaws but unfortunately it just wouldnt let me. My wife and I bought this to have a cool 5.1 type surround experience which sounded pretty good...when it worked. The bluetooth in the main unit is way to week for you to have the satellite speaker any more than like 3 feet away which isnt good if you are supposed to be able to place it behind you. It was constantly popping or cutting out and just ruined any viewing experience we could have. The bluetooth was also week if you tried to stream music to the system. We have a bluetooth record player that was right next to the main speaker but would stutter and cut out because of the weak signal. Strangely enough the satellite speaker when in stand alone bluetooth speaker mode would pick up the record player no problem with zero skips. LG has a great idea on their hands but probably shouldnt drop the wires until they can make a better bluetooth antenna.

Little flexibility

Jordnfish 3/22/2018

I bought this to place the two speakers on either side of a small room. Due to the selling point and the reason for purchase being the flexibility it is unfortunate that this does not work well. There is consistently crackling in the satellite speaker. Often times the same speaker disconnects. The main speaker rocks and sounds good. You can hear it well over the skips in the the satellite unit. When you use your cellphone next to the satellite speaker the skipping is unbearable and I often shut the speaker off. Its unfortunate that this idea was not better executed. Do not but if you use cell phones near your speakers. I should have returned it to Best Buy immediately instead of hoping it would fix itself. I am now outside the return window and stuck with a inferior product. Should have spent the extra money.

Great product - no others split like this

Ed5000 3/5/2018

Was looking for a sound bar to allow me so hear the TV sound from behind us table sitting behind couch or on side/end table. Our room is very open and tall so everything echoes - so it is very hard to here TV from the front - having a speaker behind us seems to be the best option. I looked all around for the ability to have rear speakers play noermal sound and not surround sound only. Others offer rear speakers but none allow you to switch to allow the rear speaker to have normal TV sound and not surround. But as the name goes - it also allows you to swicth it to surround sound if yiu want to do so. I asked many people at Best Buy and others about ability of sound bars to allow rear speakers to play normal sound and all told me there was no such thing. I happen to see the LG SJ7 set up and thought it may work. There was no way to look at the back of the speaker on display as they have it bolted to the display but I took a chance and it works great. I am having some trouble getting the bluetooth set up but will hopefully get that figured out for playing music from phone. Other high note is that the rear speakers only require a plug for power where as most of the other sound bars with rear speakers must be plugged into the subwoofer - this one allows you to seperate.

Very disappointed

why 1 12/21/2017

I received this sound bar 10-25-17. A few days after receiving I started getting a random humming/ buzzing sound. Shipped them to a service center came back with same issue. Shipped them to a service center again came back with same issue. Called LG customer support about the issue was told they will not send me a new pair ship them back to the service center for the third time. As of today 10-21-17 they have been gone a total of 24 days and have yet to receive an email saying they have even looked at them. Looks like by the time I do get them back over half the time I have owned them they will have been either in the process of being shipped or at a service center.
