JBL Bar 300MK2
Been looking for a mid priced soundbar and bought it after reading in Which magazine that it was good value and one of their recommended buys for 2025 Certainly enhances the sound quality of my LG TV - good bass.

A must have.......
This replaced a 2 speaker soundbar system. On setup, it throws various tones out and uses these to give you the best sound wherever you decide to site it within the room, its fully compatible with most of my apps using WiFi, Bluetooth and wired connections for the inputs. The bass is adjustable according to your taste and the soundbar has several settings depending what media you are listening to. Comes with mounting brackets and screws. A very worthwhile investment.

Great
Great soundbar only one bad thing about this and that is it’s only got one port so if like me and have tv as well as by box you can only link it to one and not both , but what a sound

Unbelievable Sound! Who needs a subwoofer!
I have to say, I was sceptical at first having come from a soundbar with a subwoofer, but WOW! I have not missed my sub one bit. The sound quality is amazing, it’s hella loud and ideal for all the parties we have used it at. Anyone thinking is switching to a soundbar without a subwoofer, you WILL NOT be disappointed with this. Buy without a second guess.

Bought the JBL SOUNDBAR as UPGRADE and BOOM!
I bought the JBL Bar 300 MK2 to replace my previous one (the regular JBL Bar 300), as I wanted to see what actually changed compared to this one. At first, I honestly couldn’t tell the difference. I even had to do some research to figure it out, but instead of just reading specs, I decided to test it myself so I could see how the experience would change. And WOOOOOW… when watching movies or any show with real bass sound, it's a boom! That’s when you really notice it. The previous one was already great, but this one feels like I’m literally in a cinema inside my own home. I even had to turn the volume down at night, because the sound was echoing through the house, and my neighbour could probably hear it too! The cool thing is that it automatically detects Dolby Atmos, and you can turn it off easily if it’s too loud. Depending on the movie and my mood, sometimes I just switch it off using the remote or the JBL One app. Is it worth it? Well, it depends. If you want that immersive cinema experience, definitely yes! But if you don’t like loud or powerful sound, then maybe not 😄

A game changer
The JBL Bar 300MK2 is just brilliant. Honestly, getting it set up was so quick and simple, zero faff, just plug it in and you're good to go. The sound quality is properly ace. I was a bit skeptical about getting surround sound without separate speakers, but the MultiBeam tech is fantastic; it genuinely fills the living room and makes movies feel much more exciting. Dialogue on TV is crystal clear, which is essential, and when I stream music, the bass is nice and punchy. Plus, it looks so sleek and smart under the telly, so there’s no messy wire clutter. If you want a significant audio upgrade without the fuss, this is the one.

everything about this was amazing
The JBL Bar 300 MultiBeam soundbar delivers impressive sound quality and a sleek design, making it a solid choice for enhancing your home entertainment setup. Its MultiBeam technology creates a wide soundstage, filling the room with immersive audio. The bass is surprisingly deep for a soundbar without a separate subwoofer, adding richness to movies and music. Setup is straightforward, and the built-in Wi-Fi allows for seamless streaming from various music services. However, the absence of dedicated upward-firing drivers means it doesn't offer true Dolby Atmos height effects, which might disappoint some users looking for a fully immersive experience. The soundbar's reliance on virtual surround processing can sometimes sound a bit artificial, depending on the content. Also, the lack of HDMI 2.1 ports might be a drawback for those with the latest gaming consoles or TVs, as it limits future-proofing. Overall, the JBL Bar 300 MultiBeam is a great all-in-one soundbar that provides a significant audio upgrade over built-in TV speakers. It's best suited for smaller to medium-sized rooms where a full surround sound system might be overkill. If you prioritize simplicity, ease of use, and good sound quality without the need for advanced features like Dolby Atmos, the Bar 300 is definitely worth considering.

Powerful Speaker
I had been looking for a good soundbar to go with my 55 inch TV and JBL Bar 300MK2 did not disappoint. I have been using this for few weeks now to watch movies and sports and sound is just amazing with Dolby Atmos Surround sound. The cinematic sound gives you this immersive home theatre experience with clear voice. Now I can understand the actors speaking dialogues more clearly. Also the Punchy bass makes listening to music a whole new experience. Jbl speakers are always up there among other top speakers.

WOW… it absolutely delivers.
The first thing that hit me was the power. This system shakes the sofa, rattles the windows, and you can feel it through the floor, even when I’ve only got it set to about a quarter volume.Setup couldn’t be easier. Apart from the bar-to-TV connection, there are no messy wires. The soundbar itself does the heavy lifting, pumping out Dolby Atmos and creating a full surround effect that still blows my mind.clearly designed with movie lovers in mind, I was hoping for something that could truly compete with my old Sony setup. And wow… it absolutely delivers.
