JBL Bar 5.1 (JBLBAR51) Soundbar Review — Good, but not Great

By Douglas Black , last updated on April 16, 2020

If you like your film, games, and music, you’re definitely not going to want to settle for the paltry built-in speakers on your TV or notebook. Even the best TV or laptop speakers aren’t going to be able to pack the punch needed to fill all but the smallest of closets with accurate, full-spectrum sound. The problem is that, when it comes to audio, there’s such a wide range of equipment to pick from that figuring out how much you really need to spend and what features you actually need is quite daunting.

I knew I wanted a fairly convenient setup with minimal wires and bluetooth, thanks to my naughty rabbit’s proclivity for chewing on cables when she’s in a mood, but also because my laptop, an XPS 15 7590, is known for having an absolutely terrible DAC leading to poor 3.5mm audio-out quality. A few hours of research narrowed my search to just a few options, all in the sub-$500 USD range.

What sealed the deal for me on the JBL Bar 5.1 4K Ultra HD 5.1 Channel Soundbar with True Wireless Surround Speakers (no gold star for the marketing intern who came up with that one) was the robust 10-inch subwoofer and the option to break away or dock its wireless satellite speakers as you please. This meant that I could have a surround-sound experience when I wanted to, but I wouldn’t be committed to having a complex setup with wires going everywhere.

I was a bit worried that the wireless speakers might be a gimmick when I first ordered it, but I’m happy to report that the JBL Bar 5.1 Soundbar doesn’t disappoint in the sound department. It does have a few issues that you’ll want to be aware of before going ahead and ordering it, though, and those issues and their impact on the day-to-day experience with this soundbar are what I’m going to focus on in this review.

The “JBL Bar 5.1 4K Ultra HD 5.1-Channel Soundbar with True Wireless Surround Speakers”, also known as the JBLBAR51, is a mid/high-end soundbar designed for home theatres.

Measuring at 59.06 x 39.37 x 35.43 inches (149.9 x 100 x 90 cm) and weighing in at 37.3 lbs (16.9kg), it’s worth noting that this comes in a very large and awkwardly shaped box when it arrives. It’s not that its too heavy to carry, but as a single person it’s extraordinarily difficult to pick up and carry about 400 m in the rain and up 4 flights of stairs (ask me how I know). Seriously, if you end up wanting to buy this and you live alone, consider asking a friend to help if you need to carry it a long distance. Just don’t forget to wear a mask.


Installing the JBL Bar was quite straightforward as far as home audio setups go. The subwoofer connects to the rest of the audio with Bluetooth, and unlike some other wireless soundbars I’ve had in the past, I’ve yet to have any problems with the subwoofer losing connection to the central unit. There are two power supplies included, with one for the sub (larger) and one for the base. The package also comes with mounting racks, but I elected just to leave it resting on top of my TV table.

The JBL Bar comes with wall mounts, but I elected to just leave it atop my TV cabinet.

Once the physical setup was complete, all that’s left to do is connect the JBL Bar with your choice of method: HDMI (through ARC, to allow for control of PC audio with TV and soundbar remotes), optical, 3.5mm, or bluetooth.

There is an included antennae which can be used to re-calibrate the base to better estimate the location of the satellite speakers when they are used wirelessly, but I have not found it necessary to use it. It’s good to have, though, should you opt for a less traditional location for them.


So, how does the JBL Bar sound? Overall, between a scale of “1” as “terrible” and 5 being “excellent” and near studio-quality, I’d give it a 4. The highlight of the system is its excellent bass/lower-frequency performance, with fairly good mids and highs for a relatively mainstream solution. The higher frequencies don’t aren’t as good as a nice set of studio monitors, but once the subwoofer has joined in, you will be very much enjoying yourself. This is all with a big caveat, though: I had to use bluetooth to get the best sound quality from it.

Big Chungus approves of my quarantine media setup.

In order of best to worst, the sound quality seems to be best over bluetooth, followed by optical, then HDMI, and 3.5mm last. I think this is where your TV and notebook come into play somewhat. The 3.5mm jack was a no-go, and filled the room with horrible static that molested every bit of sound produced by the soundbar. This seems to be an issue with the DAC on the XPS 15, the grounding of the wire, or both. The HDMI cable was my next attempted connection method, but I found that the bass seemed quite underwhelming even turned to maximum (30). I checked all the options on my TV related to sound, but couldn’t find any reason for the lowered bass response. Switching to optical (from TV to soundbar) gave me much better bass, and I was fairly happy with the way it sounded overall. Strangely, though, bluetooth seems to produce by far the cleanest sound quality with the best bass response. With the subwoofer at 15, the bass sounded much more full and clean than over optical with the subwoofer at 30. The downside of using bluetooth as your connection is additional latency and the need to use the remote to adjust volume rather than system volume (system-wide adjustments in Windows have no affect on the output from the soundbar over bluetooth, it seems).

So, if you want to get the best possible experience with this soundbar, bluetooth seems to be the way to go.

The coolest feature of the JBL Bar is the ability to detach and use two of its speakers as wireless satellites.

How does the heralded wireless surround feature fare, then? Pretty good, pre-tty good, to quote Larry David. They aren’t quite as loud once disconnected, but they make up for that by adding the additional dimension of depth. JBL advertises up to 10 hours of operation while wireless, and I think that’s exactly what I’ve been able to get out of them so far. I did notice one problem with the setup, though: the speakers do not charge while the soundbar is still “on”. If you want the satellites to charge, you will need to turn off the soundbar, meaning it cannot be used. This is a bit of a disappointment, especially because it’s not listed anywhere that I could see on the product page.

Is it worth it to have wireless surround as an option over a more traditional single-piece soundbar? I think so, as they really add to the atmosphere of a movie, game, or music session. It feels like you’re immersed in the sound, and after having experienced surround sound for a media center, I wouldn’t go back to regular stereo.

Overall Experience

The feature set of the (deep breath) JBL Bar 5.1 4K Ultra HD 5.1 Channel Soundbar with True Wireless Surround Speakers is great, especially for the price. You get very good sound quality, a lot of different inputs, and a cool wireless surround feature for a mid-range price. The problems with the JBL Bar lie in the little incongruities and annoyances, however. Having to use bluetooth to get the best sound quality despite having 3 other options is a bit ridiculous, the speakers not charging until the unit has been turned off can be a major bother if you forget to do it, and as a last nitpick, the remote is quite cheap. I hope that JBL can address these issues in the next iteration, and then I would say it would be a near 5/5 for its price range. Still though, I’m happy with what I’ve got now and what I paid for it, and I think most people will be as well.

    Hi there,
    Great review and very well written too.
    The marketing department at jbl could indeed use a stick as their product names are so confusing!
    Please, can you help me with this 5.1 bar against this one?
    What are the differences, which would you suggest I buy? I would want it to be loud and decent 5.1 surround sound as much as is possible in a soundbar anyway.
    Also please consider doing a VS review against these 2, or at least the review of this newer https://in.jbl.com/BAR+5.1+SURROUND.html
    bar would be nice to have from you guys.

      Ah — it looks like that soundbar's main difference is that it lacks the disconnectable satellite speakers. It also looks a bit smaller. So, if you want the "surround" experience, you'd want the one I reviewed here. If you just want a decent soundbar with a good bass kick, the one you linked would be better.
