Seamless and Flawless Partner to My LG C3

Submitted by Allen319 - 12/13/2023

I bought this LG S77S Soundbar to use with my new 2023 LG C3 OLED TV. Very easy to hook up and flawlessly blended with my TV for experiencing the WOW Orchestra sound that allows the use of both TV and soundbar speakers. The sound is great and I am very satisfied. I always have a preference to match the brand of the TV with the brand of the speakers. LG does not disappoint.

Surround sound for smaller size

Submitted by LAthegirl - 11/29/2023

With our last soundbar we were hesitant to get rid of because of how big the sound felt through all its speakers. Especially since this one was only the subwoofer and soundbar I worried it wouldnt feel as complete. I was pleasantly surprised Aside from the fact that pairing the sound bar with our tv to only use one remote was troublesome for us we did finally get it to hook up after multiple attempts this sound bar has been great. The quality is awesome the volume is impressive and for only having speakers in the soundbar it still fills the room We also like the unique design of the bar - - its less obtrusive than ones we have had in the past

Powerful little system

Submitted by Alex901 - 11/29/2023

The sound of this bar is really good for the size of it. When I changed my old system which was bulky I was afraid I wouldnt get the same quality and power I was used to when watching movies or listening to music but there was no disappointment. The audio quality is phenomenal it sounds neat and the powerful wireless subwoofer enhances the experience of watching movies it feels like having a little theater at home. I also love the design the previous system was wider than the fireplace and it did not look good as you can see in the picture this is way smaller and again without compromise. Its almost hard to believe there are 6 built in speakers. I really recommend this product Im sure you would love it as much as me.

Small minimal wires good sound

Submitted by snkervin - 8/28/2023

Pros: Comes with a wall mount doesnt require a separate bracket to mount to your TV. Great sound quality. Installation for wall mount included a template made it simple. Sound quality is excellent. There is no delay with the wireless conenctivity and the sound. The wireless subwoofer connected immediately without needing to be setup. User friendly remote control. Automatially turns on when the TV is turned on this can be adjusted in the settings. Can connect to other bluetooth devices or through HDMI. Cons: Not really a con but make sure you have enough power outlets because the subwoofer needs a plug and the sound bar needs a plug. We didnt realize this when setting up so we had to move the subwoofer since we only had 2 outlets until getting a surge protector.

Small smart and loud

Submitted by chithien - 8/24/2023

After quite a long delay and move across the country the soundbar finally made it to my door steps when I had forgotten about it. I was quite impressed on how loud its able to get for its relatively small size. Setup was quite easy and Im connected to my TV and gaming console in no time. It actually feels like Im in a movie theater while watching Dunkirk. Furthermore games like Call of Duty is perfect thanks to the Dolby Atmos/DTS-X capability and immersive feeling you get while playing a game. The subwoofer was strong that provide a ump yet not too overbearing. Music and dialogue quality was crisp and clear. Overall the LG S77S delivered more than I expected with its surrounding and spatial touch while keeping it real and not over the top complications.

Great Value Great Soundbar

Submitted by danmanca - 8/17/2023

This soundbar has great sound. The included subwoofer ads great bass to all of the movies as well. Things really rumble when watching action movies. Id recommend this sound bar to anyone that wants just a god front channel sound bar with a wireless subwoofer. Perfect for most viewers. This thing will blow away the built in speakers any TV. LG Makes quality products Ive owned many of them and this one is no exception. Great quality product and as I stated earlier Id give this five stars and recommend to anyone.

Submitted by adrianlop - 8/9/2023

When I got the sound bar out of the box I was kind of surprised because I wasnt expecting it to be this small well small isnt necessarily bad this bad boy is loud Bass is great sound clarity amazing This sound bar replaced another one that was about double the size of this one and I can tell you that there are barely any differences. Loving it

GREAT sound with a compact size

Submitted by itgnyus - 8/7/2023

The sound quality is PHENOMENAL and the Bass is realistic and adds soooooo much to the experience. The footprint of the soundbar is good which allows me to simply put it on a small top-mount adjustable stand. The subwoofer is a nice size and performs well It really adds to the experience in scenes that have the added bass for effect. LG has hit it out of the park with the S77S Sound Bar

The LG S77S Sound Bar Sounds Fantastic

Submitted by 1Ultimate - 8/1/2023

The LG S77S sound bar arrived in one box and it was nicely packaged it came with batteries sound bar subwoofer instructions the remote wall brackets with screws and a template for easy installation. As for setting up it comes with a template to know where to put the screws on the wall so it can be installed easily and it also comes with the screws so the brackets are on the sound bar. And the brackets are optional so if you are like me that I just lay the sound bar on the TV stand then I do not need them. I like that I was able to turn on the sound bar and it paired easily with my phone I also used an USB with music and it worked right away. And I turned on the subwoofer afterwards and it linked to the sound bar automatically. As for the sound it sounds fantastic the Dolby Atmos DTS X and WOW Orchestra makes the sound bar fill the room with sound it sends the sound forward and upwards and it sounds like you are inside the TV. I also like that even at max volume the sound does not get distorted and I can control the bass separately from the sound. The sound bar has LED lights in front to let me know several things what I am using: Optical ARC USB TV Bluetooth HDMI and I really like that it does have HDMI eARC and ARC because if it is paired with my TV I do not need two remotes all the time I can use the TV to turn on/off both. The bass sounds amazing I always place the sub at a corner to get the best bass and this one is much better than I thought. Sound bar comes with many sound modes Bass Blast AI Sound Pro Bass Blast Cinema Clear Voice Game Music Sports and Standard and each mode makes the sound great. Overall the LG S77S sounds fantastic it is easy to setup it is easy to use it sounds great and I cannot ask for more.
