You won’t be disappointed.
The sound is incredible. Way better than our last sound bar, which came with this huge boxy stereo for bass. I didn’t want to deal with an eyesore like that again, and this one sounds even better!

Awesome sound
I have other sound bars, this one is by far the best. Great sound and the surround sound coming from this speaker alone is great.

Good quality speakers, simple, with a lot of features.
This is a pretty good soundbar. Surprizingly heavy, for the size. It just baaaarely fits under my 55 inch TV. I would not tend to use it with something smaller than that. In fact, I kind of wish it was an inch or two shorter (or my TV was bigger).It’s very simple indeed. Plug in the power, plug in the ARC HDMI. Done. TV detected it and I typically control the volume from my TV remote (via HDMI).It has a surprizing amount of bass for the type of speaker it is, and quite a bit of sound stage (that is, there are speakers way out on the edge, so you get a lot of stereo effect). Like all 5.1 systems, it has the problem that when listening to 5.1 sound, the center speaker isn’t loud enough, so the music and sound effects are super loud and the talking is not. This is not an issue when listening to 2.1 or 2.0 sound, which, thankfully, is the main thing I use it for. Works well when listening to music, that is. If you use the app there is a setting for “PureVoice,” which is supposed to make it easier to understand people.Bluetooth works great, and the sound is great from it as well. I like listening to music from my phone over these speakers.It comes with some mounts for hanging it on the wall, but I don’t use them…my TV sits on a table. There is a button on the remote you can press in order to have them calibrate for the room. Works quickly and well. And there is one to adjust how loud the bass will be. There are little LED’s embeeded in the grill that show you what the setting is.This speaker really wants to connect to your WiFi. You have to install the JBL One app on your phone (annoyingly, there are tons of different JBL apps, so you have to find the right one). Luckily, you can use the app without setting up an account. The app connects to the speakers and gives them WiFi. Unlike so many devices, this soundbar actually has 5G wifi, so that was nice. It downloads a firmware update, then it wants to set up google cast. I actually do use google cast from time to time, so I was happy to do this.These speakers are a cut above what I am used to working with. And there isn’t really a lot of nonsesnse to them.

Solid Soundbar
The JBL Bar 300 has been a nice upgrade for my setup. The sound is really full and the bass is surprisingly strong for a bar without the hassle of a separate subwoofer. it easily fills the room for movies and music. Voices come through clear, and overall it feels like a big step up from built-in TV speakers. Connectivity has been smooth too. AirPlay works flawlessly (havenât even bothered with the music/streaming apps yet) and makes streaming super easy. The JBL app is good too.A couple of small downsides: itâs definitely on the pricey side for a single soundbar, and Iâve had some issues with ARC. My TV sometimes insists on switching over to the soundbar automatically when I donât want it to, which can get a little annoying. Not a dealbreaker, but worth noting.Overall though, Iâm really happy with it. Strong sound, deep bass without a sub, and simple connectivity make it a nice purchase.

Compact soundbar with impressive clarity and Atmos effects
I bought the JBL Bar 300MK2 because I wanted something simple and clean without extra speakers or wires, and I have been very happy with it. For a single soundbar, it delivers a big soundstage that feels much larger than its size. The Dolby Atmos and MultiBeam technology really help create a wider and taller sound that makes movies and shows more immersive.Voices are very clear thanks to the PureVoice feature. Dialogue stands out even during action scenes, so I no longer need to constantly adjust the volume. Music playback is also strong, with good balance between highs and mids. While it does not have a separate subwoofer, the bass is still solid for most content. It will not shake the room like larger systems, but it adds enough punch for everyday use.Setup was simple and the JBL One app makes it easy to fine tune the sound. The room calibration feature adjusted the audio perfectly for my living space. I also like that it integrates smoothly with voice assistants, which makes it convenient to use.This soundbar is not meant to replace a full surround system, and if you want deep earth shaking bass you would need to look at a larger model with a subwoofer. But for smaller living rooms, apartments, or anyone who wants an all in one option that still delivers Atmos effects and clear sound, this is a great choice.

Powerful Sound in One Device
This soundbar is impressive. It has some powerful bass and good sound to it. I love that it has such good bass without having a separate bass speaker. It was relatively easy to set up, but I encountered some issues connecting it. It took a few attempts to turn it off and on, and then the TV connected correctly. It could have been user error on my end. I downloaded the app to my phone, which is handy to have. It gives you all the functions that can be used on the soundbar in an easy to see place to edit. I couldn’t find many settings on my soundbar. The remote has buttons, but no words on those buttons. If you don’t know what the buttons say, it’s hard to know what it does.Overall, it’s a great soundbar with great sound. I am happy with it for my uses. There are some sound bars that offer more settings, while others are cheaper and provide the same or fewer options. I am happy with what is provided with this soundbar for the price that it costs.
