Sounds quality is great.

UPDATE: Okay, so the LG rep that I spoke with was rude, and by the end of our very unsuccessful conversation, she finally agreed to let me send it in for repair.

The Bluetooth capability also means you can stream music from your blue tooth capable cell phone or iPod/iOs devices.

Vine Customer Review of Free Product ( What's this? )
I recently moved to a smaller living area. In my old home, the main TV room was expansive and capable of handling a true Home Theater experience. So I'll admit that I've been spoiled by surround sound. When I moved, I didn't want to potentially blast out my neighbors on movie night so I decided to forego everything except the television speakers. You can imagine what a difference that was! And not a good one! When I saw this sound bar, I thought it might split the difference. I could enhance my sound output, increase overall performance, and still not be overly intrusive. And for the most part, this unit has satisfied those basic requirements.

Physical Set-Up: We chose to mount the Sound Bar just to get it out of the way and be positioned for optimal output for the space. Instructions were provided, but it's a fairly intuitive process as well. Everything included, the physical process of getting things connected, mounted, and in place was about an hour.

Connectivity: It's become increasingly unusual for electronic purchases to come with any necessary cables. Here, however, an optical cable is provided. Of course, you still need an HMDI cable to attach it to your TV. So you might want to have one on hand (or order one with) so that you're ready to go once the Sound Bar arrives. The subwoofer is wireless and the pairing is quite easy. Depending on your TV set-up, though (mine has about a billion devices already hooked up), you may have to play around with what is going to work best for your system.

Applications: The system applications include all the usual suspects such as Netflix, Hulu Plus, CinemaNow, YouTube, etc. Having all of that available already through both my Blu-ray and my gaming device, it's not adding functionality.

I used to have one of those 5.1 speaker systems, but my wife and I were tired of all the speaker wires all over the place.
So we wanted a clean easy system like a sound bar.

We went to Best Buy, and received some good help with all the options.
The reason we went with this was that it has a wireless subwoofer, blue tooth, and fun smart features.
I can hide the subwoofer anywhere in the room.
I can stream audio from my iPhone.
And I can watch Netflix or Hulu Plus without hooking anything else up.

The sound is good, crisp, and clean.
It comes with an optical cord which provides for superior sound quality.

The only thing I need now if for my Harmony One remote to get the right software update.
So for now, I use the 3035A model with the remote.

Now that I've managed to get this system up and running after 5 days, it seems to be operating decently enough. I encountered 2 problems during setup. I had difficulty connecting the provided optical cable directly to my television set, which has side facing connections. Fortunately, I was able to use an alternate hook up through my cable box, which has an optical outlet.

Pairing the subwoofer with the sound bar also turned out to be problematic. I couldn't get the sub to pair following the instructions in the manual. After talking to an LG rep on the phone, who was courteous but unable to help, I eventually got a solution from LG via E mail. The procedure is to hold down the mute button on the remote control while simultaneously pressing the stop button (the one with a little square symbol) on the sound bar. When the display says "remate", the pairing should be complete. I tried this and it worked like a charm.

Vine Customer Review of Free Product ( What's this? )
I was excited to add this component to my 47" LG TV. TV speakers just keep getting tucked away so any way to improve sound quality is welcome.

The box was huge and is not inside a plain Amazon box; in other words, all your neighbors will know what you've just received. This could be a bit of a theft problem. The size of the box is to accommodate the sub-woofer; the sound bar really isn't very big.

Set up was simple, but I would have liked more than pictures in the setup process. (There is a set-up DVD included, but it didn't seem worth the time to use it.) The optical cable is included, but the HDMI cable is not. The internet connection was quick and easy. The power cable input into the sound bar is very loose; once it's in place it won't fall out, but it did several times during set up.

The sub-woofer does not need to be connected and can be placed anywhere in the room. It does require power, though.

Unfortunately, there are advertising/content stickers on the fronts of the sound bar and the sub-woofer. They're not the easy peel-off kinds; in fact, I had to use Goo-Gone to completely remove them. Even then, there was quite a bit of smearing smack dab in the front of the units. It would have been nice if they'd used decals, not stickers.

Of course, the sound isn't as good as the full-on 5.1 I have in my living room. This is just the bedroom TV, so it's a cut above the TV speakers, but not surround. Still, it's quite clear and not as tinny as the TV.

Because I have an LG TV, the sound bar turns on when the TV is turned on (with my TiVo remote). There is, however, about a 22-second delay from the time the TV is turned on and the sound kicks in. At first I thought I was not setting it up correctly, but is was just the lag.
