I got this as part of a promotional deal with my LG 47LM6700 3D TV. It is not being used with that TV since I have a proper surround setup in my family room. I am using it in my bedroom with the Samsung TV the LG replaced. One thing about sound bars is that they usually need to be placed in a square or rectangular room to get a good simulated surround effect. My bedroom is sort of an odd shape so I wasn't expecting much.

Upon unpacking I was disappointed by how light the subwoofer was; it felt cheap, but looks good. Pairing the subwoofer and a HP Touchpad tablet to the sound bar was an absolute breeze. But the Bluetooth range is poor; only about 10 feet. This is the main reason I only gave it 4-stars. The other thing that disappointed me was that LG used toslink instead of hdmi for the sound. This means no CEC; you cannot use your TV remote to control the sound bar. I have a universal remote that will control both, but I can see why some people are upset by this poor design idea. I would have given it 3-stars because of this, but then I turned it on.

The sound is usually what's most important. For a < $300 sound bar package I was pleasantly surprised by the sound quality. Yes the bass is boomy, but the vocals from the sound bar are actually quite excellent. Again, this is a cheap system for my bedroom, so I am not trying to compare this to my Hsu Research surround setup in my movie room or my Bose Acoustimass in my family room. Plus the simulated surround sound works pretty well in my odd shaped bedroom. It has plenty of volume too. To anyone suggesting that it's about the same as their TV speakers; you must have a damaged unit or reviewing the wrong item.

We received this for free with the purchase of our LG 55LM7600 3D LED TV. I figured that since it was being offered for free that it probably wouldn't be that great. I was a little interested in the fact that it had a wireless sub-woofer though.

The box was a little bigger than I would have though it would be but I was happy to see that LG used some extra packaging to ship these for sale.

Hooking this up was extremely easy. One cable for power off the back of the sound bar itself, and a single optical cable to the back of the TV. It was nice in that the sub was wireless so we were able to just sit it off to the side.

I saw one other review stating that this unit didn't sound as if it was 300 watts. Personally, myself and my wife think that this unit sounds really good. We don't really use the 3D sound effect as we honestly can't tell much of a difference. This may just be us though.

I do wish that this unit had some different options as far as connectivity.

I do appreciate the fact that LG stuck with Bluetooth connectivity, instead of going strictly with Apple Airplay for compatibility sake. We only use Apple in our house so Airplay wouldn't have hindered us at all.

Is this my ideal sound setup for our living room / movie room? Not at all. Do I think this would work in a smaller room? i.e. bedroom / office Yes...150% YES!

Overall, I gave this a 4 due to the few shortcomings I feel the unit has.

Look: 4/5
Sound: 5/5
Ease of use: 5/5
Options: 4/5
Value: 5/5

1. Features: Bluetooth is great. Works flawlessly w my iPhone. Pre-designed EQs sound good and offer variety. "3D Surround" sounds great. Seamlessly integrates w TV by detecting presence of optical signal and turning on or off automatically. *Wireless subwoofer is cool, but may contribute to the deficiency of adequate bass performance.

2. Sound: Mids and highs sound crystal clear. Pretty amazing actually. Breadth of the mids and highs is truly impressive. Bass performance is very deficient--much less bass performance than with the cheap $100 system I replaced. This is disappointing. I suspect this may be due to the subwoofer's wireless status--perhaps it just can't communicate the bass response as well wirelessly. (?)

3. Appearance: High-quality materials. Very attractive. Glowing LED light on subwoofer is extremely annoying.

4. Overall: Ambiguous performance that I personally can live with. Wish there was more bass presence. But the rest of the spectrum sounds awesome.

I brought this sound bar system last week to complement my LG LM7600 3D TV. It is a nice basic system with decent sound quality. It is easy to set up and has some nice features such as bluetooth connection and wireless sub-woofer. Priced between $200 - $300 it may be among the top three or four sound bar systems in its specific category. While it is by no means a replacement for something that would appeal to an audiophile, it does a nice job as a basic sound bar system.

One issue, surprisingly though is that this sound bar system does not have any HDMI inputs/connections. It can only connect to the TV via a Toslink Optical cable. With no HDMI inputs there is no support for HDMI ARC connection which would essentially allow the TV remote to also control the sound bar system. So now I have to use 3 remote controls to manage my entertainment set up - first for the Cable/Satellite box to navigate channels, second for the TV picture settings & feature access (i.e. Netflix, etc.) and third for the sound bar system. Pretty quickly it gets annoying to use three remote controls.
