June 2020: still functioning perfectly. I think once or twice I’ve had to unplug the subwoofer to get it work again. Very rare occurrence. The remote can be slightly difficult to get to work (needs the right angle) but I almost never have to use it because the TV controls it. Great sound bar, 100% recommend.December 2019 update: still working great.Original 2018: I got this speaker a couple weeks ago and it's been working great so far (November 2018). I plugged in both the HDMI ARC cable and the optical cable, per the instructions and it started working after I turned the TV off and then on. I

This relatively low cost sound bar has remarkably good sound for such a low profile. Setup was easy. It came with HDMI and optical cables for attachment to the TV. I attached the HDMI to the ARC (Audio Return Channel) HDMI connection of my flat panel and just turned it on. The TV recognized the sound bar by turning off its internal speakers and playing sound through the sound bar. Additionally, it shows the audio level bar on-screen whenever the TV or sound bar remotes are used to adjust the audio level. I plugged in the wireless subwoofer and it connected automatically to the sound bar, but t
This speaker system is very reliable and works well with my Smart TV and my phones. I have been using it for the past six years with no issues. It is portable and durable, working just as well as it did when I first bought it. I have moved it to two different apartments and it easily transports from one apartment to the next. It is pretty discreet, blending well with my Smart TV console.My main critiques are that the sound system doesn't always interpret the sound as best as it could, especially the lower registers of the bass guitar and the bass drum. It is good at highlighting the treble sou
What a great soundbar. I purchased this brand and model as a replacement for another brand that quit working and then the company went out of business with no warning. The sound is superb and the bass coming from the wireless subwoofer has a nice subtle kick to it for all your music or tv shows and music, especially for its size. Setup was a breeze and operation is very simple. The remote is very intuitive and allows for all sound adjustments. It even has adjustment for increasing voice clarity. Soundbar can be mounted on a wall, tv stand or set on an entertainment stand.
Huge upgrade for the money. Louder than you will ever need. Bass is decent enough to make me happy. Don’t expect to rattle the windows but this adds enough low end to keep a guy happy. Pleasantly surprised.
Lots of reviews here, and many complain about the "auto-off" feature that turns the soundbar off if there's no audio input for 15 minutes. YOU CAN TURN THIS FEATURE OFF. Hold down the "TV" button on the remote for about 5 seconds; a light will flash on the soundbar and the feature will be OFF. Repeat the process to turn it back on again.Now that that's out of the way:I've been using an A/V receiver and hi-fi speakers for a 3.0 (front right, left, center) experience. The problem is, with an over-the-air antenna with TiVo DVR, Roku, smart TV, and disc player, it's gotten very complicated. I turn
This is a mediocre sound bar for the price. I wasn't expecting a lot for $200. Perhaps my expectations are high in the A/V department. I just moved from a house where I had built a 7.2 home theater system. It was a modest system, but nothing Home Theater magazine would feature. So, I have a bit of understanding and experience with home theaters, audio and video. In my new house I don't have a home theater yet, and I needed something that was better than my TV speakers. I knew I wasn't buying a home theater system with this purchase, however. And my 3 star review is not based on this bar's soun
Fantastic soundbar system. I was nervous about the sub but it sounds perfect and not overwhelming. Plus, you can control the bass. Crystal clear sound, miles above my previous soundbar. Highly recommended!
