Looks and sounds Good. BUT and a Big BUT, mine too has the same issues with other reports on here in the fact that it keeps turning its self off. I have only had it 4 weeks so mine is going back to currys at the weekend as a faulty product. I will update this review and star rating when the issue is sorted out. This is obviously a known issue, so I shouldn't have too much of an issue taking it back I hope..

Update 08/12/14
Well I finally got round to sorting out the problem, As reported by other reviewers my unit kept switching off this must be down to the fact I was running this wireless,with my Modem & Router mounted just the other side of the same stud wall the tv and soundbar is mounted to. obviously causing to much interference and shutting down. So i had tried an optical lead I had kicking about, well still no joy there. I was all set for taking it back when I thought maybe the old optical lead is kaput so bought a new one fitted that and Hey Presto works a treat with no issues. so i'm giving it an upgrade in my review to 5 star, Ok so it's not as good as my old onkyo 5.1 set up but I wanted a more compact set up without the clutter of wires etc. More than loud enough

Device comes well boxed and is easy to install. I use an optical cable from my LG TV straight to the soundbar. I find the sound crisp and sharp. I have tried all the DSP varients on this device but I keep coming back to Cinema and News.

The Bass is fine from the wireless sub, with plenty of punch sharp and crisp again. It does not bounce sound from the walls like the Yamaha 2500 but then again it is £400 cheaper.

All in all a great buy and very happy. So far mine does not switch itself off as I have the sub well away from a router.

I recently bought an LG 370v Tv which doesn't have bad sound to be fair, however was after something to just give it boost and for something the whole family could use, especially with a Bluetooth option. I basically went for this one as it would sync with the lg tv using the arc function or wireless function. Plus the low profile of the speaker fits nicely on the weird curved stand of the tv. The speaker also does not block the infra red of the tv like many other of the brands around.

Overall setup using the hdmi out arc feature works great and it controls the volume in conjunction with the tv, also the wireless mode achieves the same. Sky remote works in conjunction with wireless mode as well.

Sound is clear and crisp and for non audio people in my house hold its great. The blu tooth feature for our iPads is great and is becoming one its main uses.

However this is were it falls down slightly and a bit of a deal breaker with the wife. If you have the bar set on arc mode or wireless mode through the tv. After using the blu tooth function you have to go back into the tv settings menu to reactivate the arc or re-pair the bar to get the tv sound back.

I am assuming that if an optical cable connection you won't have this problem, as you can switch between that with function on the remote and bar. Though I suspect you don't have the tv control that you have with the arc or wireless mode.

I will have to get an optical cable to see. Unless I am doing something wrong, drop me a comment if I am.

Apart from that is a great match for the 42 inch tv, with its low profile and various input connections and options.

Style Name: NB4540A Verified Purchase
I never give five stars, but I just have to now. I bought my soundbar from electricalsuk and took a leap of faith with the used/returned/unsold. Lo and behold the soundbar is in perfect condition besides some very tiny marks on the bottom of the socket area and it works perfectly. Not bad for 139 eh? It also came the next day, very early considering the shipping!

Now onto the product. This was meant to be an upgrade from the LG NB2540A and it completely blows it out of the water with technical performance and my god it looks so good!! Everything is clear and balanced with a long range, and the wireless subwoofer is VERY powerful, with adjustable levels of course (subwoofer button and volume buttons). It instantly connects when you turn the soundbar on so no worry there. Also the soundbar itself has display text in it's centre, a nice point over my last one. Voices sound natural and crisp, and sound fx in video ganes for example work seamlessly with the rest of the audio, either way there are 'sound effect' settings to change that too.

You can use optical, hdmi (in and out sockets), usb (like a flash drive), LG sound sync, auxillary (portable), or bluetooth for connectivity. Just make sure to keep your device away from potential interference. Some fare better than others (my playstation vita has never dropped out) but a a charger that had finished up, created a lot of interference for my yoga 2 pro.

All in all I couldn't be happier. This is a high level soundbar and if you're looking to upgrade this is the definitive choice. Just keep it down alright?

Bought this from Curry's (UK) for £200

It looks excellent. Sleek and metallic, the slim nature of the bar and the matching brushed metal style of the (admittedly rather large) wireless subwoofer match the 49inch lg 4k TV I have perfectly. It's only 84(ish)cm long so it's probably around the same length as most 40inch TVs.

Sound-wise I was originally only slightly impressed. I hooked the TV up via the LG Wireless Soundsync option and, on the "standard" sound preset it was fine, albeit lacking in the midrange. Switching to "cinema" mode (which most reviews say is the best option) was pretty terrible... Balance was all over the place with most voices completely drowned out by anything else onscreen. The sound would also occasionally drop out for no apparent reason.

Turns out it was just down to the wireless soundsync (which is based on Bluetooth)... I'm guessing there's just not enough bandwidth available for high quality audio. Switching over to optical completely sorted any issues with balance and the sound no longer randomly dropped out.

The standard mode is heavy on the highs and the sub takes care of the bass (I had to turn it down to about -6 in our relatively small front room), perfectly fine for standard TV viewing. The Cinema mode is brilliant for films and has a definite sense of space that was lacking from the TV speakers. Voices are toned down from the slightly sharp levels on standard and the midrange is bumped up a little, offering a far more rounded experience. Music mode also adds a minor reverb and emulates a larger listening environment pretty well... I haven't bothered testing the rest yet.

In the end it's an excellent bit of kit for £200.
