A great soundbar!
The JBL Bar 300 is a compact soundbar that packs a mighty punch. From the factory, JBL provides everything you need to get started. With the Bar 300, you get wall mount brackets, an HDMI cord, a power cord, and a remote with batteries. I wanted to mount my Bar 300 below my wall mounted TV, so I ordered additional universal mounting brackets and got to work. The bracket mounts on the bottom of the Bar 300 are very shallow; I had to be careful when attaching the brackets to not over tighten the bolts.
After getting the Bar 300 fixed to my TV mount, the rest of the setup was a cinch. I used a Digital Optical cable to connect my Bar 300 to my PC. My PC is able to output Dolby Digital at 192kHz to the Bar 300 and it sounds fantastic. On the Bar 300, I adjusted the bass to the max, level 5, and didn't adjust any other equalizer settings. I also allowed the soundbar to automatically calibrate before listening to any music. Afterwards, I listened to my favorite demo song, Comfortably Numb and was blown away. I was surprised at the bass the Bar 300 provides without a subwoofer. It also clearly presented the high notes with great clarity. Watching Twitch streams allows the Dialogue Enhancement tech to really shine. Broadcasters now come through over the gameplay and music without being muffled.
Overall the Bar 300 is a great compact sound bar that brings JBL's high quality sound to the living room.

Bars have come along way- easy setup
Simple set up- great sound. Getting the system out of the box was easy and pairing was simple. Found is great. It is a great add to any tv system. I replaced wired sound system for my tv in our family room- sound is rich as the traditional wired systems. This has deep output that us comparable to more expensive brands.
Recommended to any home systems andsmall office tv setups. Blends in we'll with my furniture- doesn't look out of place.

Enhance your listening experience with JBL Bar 300
JBL bar 300 definitely enhance my television viewing. It's very easy to setup up on my television through bluetooth. I love the calibration tool which makes it easier to use depending on the size of room that your device is in. The Bass is pretty solid as well.

Total upgrade over built in TV speakers
This soundbar really projects well. I have the bar setup in a huge room with 30ft ceilings and it cranks. Having experienced JBL's Bar500, it definitely does not have the hit of a subwoofer included setup. But the sound is so full and detailed. Setup was extremely easy. Audio in and power cord. Done.

Makes for a fantastic movie experience!
JBLs soundbar is a fantastic addition to my home theatre setup. The audio is fantastic and the Spatial surround sound makes movie watching a relish.
In addition, the soundbar is remarkably easy to setup and configure.

Pleasantly Impressed!
I had not yet used a soundbar as a stand-alone system so was a little skeptical of getting the promised results. The Bar 300 set up did not disappoint! It more then delivered the sound features I was expecting, including a clean low end bass. This was accomplished despite the absence of a dedicated subwoofer. Most of my apprehension centered around the desire for good "separation" involving the right and left channels. I didn't envision this being possible given the length of the soundbar. I was dramatically wrong, and was beyond pleased with the superior sound delivered by this excellent product. Simply a must buy for anyone who wants simplicity in audio delivered in a compact and attractive package.

Delivers a punch while being functional
I really enjoy the price point and how simple this surround sound speaker is. It's nice and loud but the bass also packs a punch and definitely delivers throughout the whole house. The feature that set this product apart is the fact that when you set it up there's an option to use the built in Dolby Atmos that configures the room to find out the most effective way to deliver the sound thru the house.

Compact size, BIG sound!
My son got a new TV in his room and needed a small soundbar to get better audio in his room. This is where the JBL Bar 300 comes into play! It's a small soundbar with a big sound. My son loves gaming and listening to music so the Bar 300 definitely helped, a lot! The unboxing experience was unexpected, the sound bar came inside its own velvet-like bag(maybe feels like cotton) and all the accessories were well packed in a smaller box the accessories it came with was a control, power cable, 2 batteries, HDMI cable, wall mounts and hardware, and product info/setup guide/warranty. I was impressed by this presentation. Setup was easy and it took a few tries to connect the Bar 300 to WiFi but nothing that stressed me out. The first thing I did was download the JBL One app to use it as a remote control, my son is 5 and he's very good at loosing remotes so I hid the one that came with the Bar 300 and used my phone instead. Calibrating the equipment for his room was simple, just hit the calibration option in the App and the soundbar took care of the rest. When it comes to sound, it was louder than expected and the internal sub definitely helps a bit during action scenes and punchy music. He has a smaller room about 12' X 12' and Dolby Atmos content sounds good since audio is constantly being bounced off across the room. I like the way the Bar 300 sounds and so does my son since it is waaaay better that the tv speakers. The only thing is that my son has a 4K streaming box, the one with bitten fruit, and a gaming system. The TV only has 1 HDMI input so we are using it for the streaming device since it has 4K pass through and HDMI is needed for Dolby Atmos content. The gaming system is being connected to the TV and through and optical cable to get the audio to the Bar 300. If you are looking for s small soundbar for a bedroom then the Bar 300 is what you are looking for.

Should be at the top of your list!
JBL BAR 300 review by a semi-cranky guy
The review will be broken into likes, dislikes and perceived sound quality and a conclusion

Starting with the likes, Once out of the shipping box gently surprised there was a carry handle for transport. Packaging as expected.
Out of the box the weight of the unit said quality. The finish and the seams were even.
Placed in front of my 50" TV visually acceptable. Would work very well with a 40" TV.

Plug in the power cable, the optical cable, download the app on my phone and go. Nothing unusual, just normal including the running of my music streaming service via blue-tooth. Hey a three band equalizer in the app.

The LED panel under the material on the right side is to me a wonderful upgrade. Looking I know the volume level, the status, etc. The included HDMI cable looked to be decent. And the mounting brackets black painted steel. And a mounting guide!

Now for the dislikes. First I would like to see a 3.5mm audio input. Would be helpful with older TV's.
Within the phone app I wish there was a volume control. Not really needed, but…

Sound evaluation, I LIKE IT!!!!!
TV for me is primarily the spoken word. Maybe a musical now and again or a music video here and there. The spoken word is now so much more intelligible. Which makes it so much easier to follow along be it a movie, a news cast, documentary, or whatever. And at volumes louder than I care to listen.
I should also point out where I sit in relationship to the BAR 300 very little change in audio quality.
The musicals or music video are not by any means flat toned. Vocals are predominate and the actual music is kind of reduced. This is a give to get vocals easily understood. Gives anything with music a different yet pleasing texture.

Overall a pleasant addition to my setup and glad it is there and being used everyday.

Great sound for a stand alone bar
of the box, this speaker sounds crystal clear, making it perfect for dialogue/ movies. However, it did seem like it was missing some heavy bass. The calibration feature on the sound bar is great! It helped produce better sound depth and gave it the bass that seemed to be missing, so I highly recommend utilizing those features! Considering that it is a single stand alone bar without a separate subwoofer, I think the overall sound quality is better than expected. A small annoyance to me is that the source button ON the bar will turn it on but I cannot figure out how to turn it off without using the remote. Lastly, the thing I love most about this sound bar (and JBL in general) is that they include all the hardware and very detailed instructions/ guides for mounting the bar on a wall! They even include a template to help measure where to place the hardware!
