Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 918-495-0586 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Adaptive Sound for your content

Adaptive Sound Control is LG's sound analyzing technology. It actively identifies what's playing and automatically adjusts sound settings to create the ideal audio experience to match the content you're watching.

Auto Sound Engine, sound balance at any volume

LG Auto Sound Engine optimizes your sound at any volume level and maintains precise frequencies at all times. This provides the appropriate sound balance regardless of the volume.

Auto Music Play, music that follows you

Sound starts the moment you enter the room. With Auto Music Play activated, the sound bar can automatically take over the playback of the audio from a connected device the moment it senses the device is nearby.

Control with your TV Remote

Control your Sound bar's basic functions with the remote you currently use the most, your TV remote.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
