Great sound

Davislmatt 12/12/2020

Bought this to replace aging sound bar that suddenly stopped working. A lot of sound bars on the market so I needed to do my homework. This sound bar produces clear voices deep and full sounds.

Subwoofer Disconnects

David 11/4/2020

I have had this item for a couple months now past my 30 days sadly. Sound is great...BUT Subwoofer disconnects and reconnects every few minutes. Very annoying and noticeable when listening to music watching movies and playing games. I wish there was an option to connect the sub to the soundbar with a wire. I only got this soundbar because I have an LG OLED TV and its compatibility but I am very disappointed for what I paid for.

Everything you need is included in the box Excellent sound. Easy to connect. It comes with optical cable which was a pleasant surprise. Subwoofer connected seamlessly and it sounds great with great bass I also connected the rear satellite speakers for awesome surround sound. I would highly recommend this soundbar to my friends and family. Disclaimer: I received this product at a discounted price in exchange for my honest review.

The Soundbar Ive Been Waiting For

dansullivan 10/23/2020

This was such a great investment - my family loves this sound system. We got the SN7Y Soundbar with Wireless SubWoofer and the add-on surround sound speakers. The soundbar alone is so great the sound fills the room and the settings allow me to get the right sounds for anything I watch. The subwoofer gives the right deep bass sounds to really. get movies video games and music just right. Connection was seamless for everything. I love that the system switches automatically to Dolby Atmos or DTS when it is available. I keep it set to 7.1.2 and the Bass Boost but it all varies by what you watch. It is very easy to pair the soundbar to my laptop phone or the surround-sound speakers so I give LG a lot of credit in that. The only knock against it is I cannot turn the display off on the bar - I wish it didnt say ARC all the time. Ive tried and only been able to dim it. I hope LG puts out a software update that allows me to set it so that the display goes off after a time of no input. I highly recommend this soundbar - the price is right and it gives you the quality of much more expensive units. I did receive this product at a discounted price for my honest opinion.

Very Impressed

foztracker 10/2/2020

Thoroughly impressed with this soundbar and sub. Being my first LG audio product I didnt know what to expect. As soon as I got it set up all I wanted to do was sit and listen for the rest of the afternoon. Starting with the packaging it was simple and efficient. No need to pull out any tools or make a mess in the living room. Also not a lot of waste to have to dispose of which is a huge benefit. Setup was quick and easy the provided instructions were helpful and easy to follow and the setup itself was not complex in any way. Total time from the package arriving on my front step to listening to music streamed from my phone was less than 30 minutes. The audio quality is crisp and consistent at all volumes and the default mix between the sub and the soundbar is excellent. The built in mixer is very handy as well. Overall very impressed at the audio quality especially for this price point. This soundbar is packed full of features looks sleek is well designed and sounds great. And as an added bonus comes with all the hardware and cabling you need to set it up in any configuration you would like to. All in all I highly recommend this soundbar.

My senses are awoken.

Metzgo 10/2/2020

After buying a new TV and realizing that the speakers are sub par I originally purchased a budget branded soundbar sometime ago but quickly learned that that just wasnt enough for me either. I was ecstatic when my LG system arrived it was a box the shape of a strange guitar. I couldnt wait to get started. It felt heavier than I imagined it would but that only made me anticipate some optimism of quality inside. I opened the box carefully as I usually do to make sure that everything is in good shape in case I need to return it unsatisfied. I was pleased to see that every single piece inside took up the exact amount of space the box could muster as to ensure that nothing was able to jostle about inside durning transit. The directions were quite easy to understand and quite to the point. Within minutes it was up and running. The sound was on the sub was working I could hear everything I mean everything. I couldnt believe how much I appreciated hearing the thud of doors closing and creaking of floorboards as people walked across old wooden floors in mine and my wifes favorite show that I wont mention. Even the clanging of silverware during dinner parties. I could hear it all so much so actually that at times our family dog would bark when startled at some random sound coming off the background. It took a few days for Teddy to get use to hearing the new sounds about but after awhile he settled right in and no longer is startled by the surprises. Pardon the pun but it does speak volumes on the quality of this system. The whole point is to hear the sounds that these tv and movie studios spend so much time and effort to record to make entertainment that I pay for. I really do want to escape and be immersed into the movies and shows I watch. Its the whole reason I give my downtime to tv it might as well be well spent rather than just ok. The sub woofer was easy to pair the soundbar worked immediately with my universal remote. I love how it turns on when the tv goes on and shuts off when the tv is off. The remote that came in the box worked just as well the buttons are nice and big and easily placed in the most convenient location which Ive already easily memorized. I also found things easy to shuffle through the different options and customize the sound to my liking. Some shows I focus more on speaking and when the wife is away I jump the bass up to hear my favorite action movies explode and soar. Very pleased.
