What people are saying

Rated 4 out of 5 by from Happy with it for the most part. Sound is great. It’s very good for normal tv viewing and superb for movie viewing. Subwoofer paring is simple. Easy to mount. Here’s the only real disappointment…the Bluetooth range is awful. You can't be more than a few feet away before it starts braking up the signal. It's actually the worst Bluetooth product I've ever used. I have a portable Bluetooth speaker from another manufacturer and it works wonderfully from over 50’ away. You’re are LUCKY if you can get 5 feet from the soundbar. Another small disappointment is connecting to the tv. I have an LG tv and I thought they would seamlessly work together but that did not happen. I am not sure if it's the tv or the soundbar making it challenging so I can’t take anything away from my soundbar rating. When you get them working together the sound is fantastic. If Bluetooth is important to you DO NOT buy this soundbar. If you are using it solely for tv/movie viewing it’s great.

Rated 5 out of 5 by from Great buy I bought this awhile ago and I haven't regretted it for a moment. The sound quality is great, the features are awesome.. I can watch Hulu, Netflix, HBO and a ton of other networks just from my soundbar.. and the price is a bargan! The only thing I wish it had was Amazonprime but really I have no complaints

Rated 3 out of 5 by from Good Soundbar This is a good soundbar with great sound for movies and video games. The bass can get extremely loud as well with good clarity. The surround sound quality is pretty solid too. However I have sent mine in to get fixed before for issues. Every now and again, the sound goes away and every voice sounds like they were sucking on helium. It has happened less since being sent in to LG, but it still occurs. If you are looking for a soundbar, I would recommend not going with this one and looking for a newer model.

I have the LG NB3740 sound bar. I have it connected to my LG Smart TV using an  HDMI (ARC) cable. When the sound bar comes on, it goes to Home or Optical not ARC. What do I need to do?

Asked by: Rory B
We regret the inconvenience you have experienced with this Sound Bar. Be certain that only one audio connection (HDMI/ARC) cable is connected and that the TV’s Audio Out setting is configured for the ARC output. It may be suggested to utilize the OPTICAL port, instead of the ARC, if adjustments to the audio configuration is undesirable. With this connection, the INTERNAL SPEAKERS+OPTICAL setting can be set, and the external sound can activate automatically. For additional information or clarification, please contact our Customer Interactive Center at 800-243-0000.

Asked by: Ale0421
We appreciate your interest in this Sound Bar System. This model is designed to connect to a television using either the OPTICAL Digital Audio jack or the HDMI / ARC jack. The compatibility of this alternate connection will depend upon the design of the TV.
