All of us here at Speakergy are very serious about our music and our gear – the most beautiful musical sound, the lowest distortion, the highest fidelity and neutrality, and all of that.

But sometimes we just want our music loud – no, not just loud, but as loud as humanly possible!

So it seemed a great idea (and a lot of fun) to put together a list of the loudest portable Bluetooth speakers on the market today – first and foremost considering the absolute maximum sound pressure level, but also factoring in sound quality, build quality and reliability, design and features and all of the other important bits that make a speaker great – and really, really loud.

If you’re in a hurry and just want the recommendations, we have the full list loudest of the loud below.

P.S. We were not able to pick one “overall” best speaker, so we are listing them both. You can read why later in the article.

How Loud Can a Bluetooth Speaker Play?

Audio manufacturers, all concerned about our health and well-being and junk, put limits on the maximum SPL (sound pressure level) of Bluetooth headphones which, to be fair, do sit pretty close to our precious eardrums.

But there are (usually) no such silly limits on the maximum volume a Bluetooth speaker can achieve, and some of them – like the ones on this list, which all achieve at least 100 decibels – can reach almost frighteningly high levels of volume and musical energy.

Indeed, Bluetooth speakers are only limited by power and design, budget, and engineering considerations, although these may not always go the way we might expect.

For example, power is a highly misleading specification, and higher power does not necessarily mean more volume – in fact, it often doesn’t. Driver and cabinet design, and the efficiency of a speaker, are much more important, and highly efficient speakers with less power behind them will play louder than a lot of Bluetooth speakers with huge inbuilt amps.

[All that said, I will include power specifications for each and every one of the loudest portable speakers on this list, because, well, I’m a geek, and it will provide you with some nice fodder for bragging.]

Another important example is budget – yeah, some of the products on my list of loudest Bluetooth speakers are pretty pricey, but a higher price does not mean louder sound, any more than it necessarily means better sound, and some of the loudest speakers on this list are amazingly affordable – and, at any volume, sound fantastic.

What Should You Look For in the Loudest Bluetooth Speakers?

So if the price isn’t the most important thing, and power isn’t the most important thing, what is important?


Ok, let’s all calm down, and be a bit more specific. I think the most important things to consider when choosing a really loud portable Bluetooth speaker are:

  • Volume: The ability to really fill any space with nearly uncomfortably loud sound pressure
  • Low Distortion: To make sure that, even at maximum volume, the sound actually isn’t at all uncomfortable, and in fact is clear and clean.
  • Sound Quality: Beyond the important factor of low distortion, we want a speaker with great detail, open and transparent sound, excellent musical energy even at lower volumes, and deep, powerful bass.
  • Build Quality: The loudest Bluetooth portable speakers worth buying not only play loud, but are built well enough that they can withstand those higher levels for extended periods, as well as a bit of abuse, and should also offer real long-term reliability.

There are a few other important considerations, like latest-gen Bluetooth technology, nice features, a good design, and real usability, look, style, fit and finish, among others, but I’ve taken all of this into account.

So let’s have a look at the best and loudest portable Bluetooth speakers on the market today!

The Loudest Bluetooth Portable Speakers for 2024

The Loudest Bluetooth Portable Speaker Overall

Just How Loud? – JBL PartyBox 1000

  • Power: 216 Watts
  • Spl: 122 Decibels

Just How Loud? – The Soundboks

  • Power: 216 Watts
  • Spl: 126 Decibels

I know, I know – everybody and their uncle will tell you that the generation 3 Soundboks portable Bluetooth speaker is the loudest you can get – and yes, at 126 decibels of maximum SPL (sound pressure level) it actually is.

But actual listening will tell you something different. I have heard both the Soundboks and the awesome JBL PartyBox 1000 in the same environment, and the JBL is simply louder. Not on paper, as it has a still scorching but second-best rating of 122 decibels, but the dynamic energy, the raw power, and the apparent loudness of the JBL are all stronger, and the overall impression is that the PartyBox 1000 is just putting out more volume.

All this said, there are other considerations. The Soundbok is usually less expensive, and is definitely more portable – it has a rechargeable (and swappable!) battery (the JBL is AC-powered only) and excellent battery life.

As far as sound goes, they’re both pretty amazing, with deep, powerful bass and real clarity. At the end of the day, though, I would have to opt for the JBL PartyBox 1000, with deeper, faster bass, more neutral and accurate sound overall, less distortion, and more detail.

We’re kinda splitting hairs, though, as they both have amazingly clear, powerful sound and slamming bass, and they both represent great values at their admittedly steep price points, and I would absolutely love to have a Soundbok (of course, it’s me we’re talking about, so what I really want is both!).

But the JBL PartyBox 1000 is the loudest portable (or at least somewhat portable) Bluetooth speaker I’ve ever heard, and with its basic mixing capabilities and DJ controls it really is a party in a box – a beautifully made and beautifully designed beast with simply awesome sound, and highly recommended.

If you really want this highest level of volume but are a bit more limited in budget, you should definitely consider the JBL PartyBox 710, which is pretty darn loud and enjoys much of the design benefits of its bigger brother, or the insanely loud Soundboks Go, which is significantly less expensive than their famous flagship.

Best For Professional Use

Just How Loud?

  • Power: 160 Watts
  • Spl: 109 Decibels

Some people are looking for a portable Bluetooth speaker with loud volume for professional sound reinforcement work, like for parties, special events, meetings, or presentations, and even DJ gigs, and the Bose S1 Pro is a perfect choice.

The S1 Pro has one of the highest volume rating periods – a thunderous 109 decibels maximum SPL – and even at this frighteningly loud peak there is nothing to fear – the sound is amazingly rich, detailed and open, and completely free of distortion.

The build quality of the Bose is, like the volume and the sound quality, truly next level, and up for even the occasional punishment professional use and portability can bring. The fit and finish are also first-rate – this is Bose, after all – and the physical configuration is ideal for projecting all of this superb sound into any space.

The Bose S1 Pro portable Bluetooth speaker has nice basic mixing for two inputs, like voice microphones or musical instruments, with not just relative level adjustment but also reverb, bass, and treble controls for each.

To me, this is a very impressive speaker system, with a sound that is not just huge but beautiful, a simple and lovely appearance, and amazingly high quality on all levels. I call the Bose S1 Pro the best professional Bluetooth speaker for high volumes, but in fact, I would recommend this surprisingly affordable and surprisingly refined speaker system to anybody.

The Loudest Bluetooth Speakers for Your Party

Just How Loud?

  • Power: 240 Watts
  • Spl: 104 Decibels

I’ve already given big love to the enormous and slightly intimidating JBL PartyBox 1000, which I find to be the loudest portable Bluetooth speaker overall, but we really should look at the whole PartyBox line, all of which offer intense maximum sound pressure levels and that same big, beefy JBL sound.

One great thing about the PartyBox line is that they all (except for 1000, which is almost dangerously loud) have the same maximum sound pressure level – an impressive 104 decibels – so you can choose any of them and have pretty much earth-moving volume for your next party.

All three of these less expensive (though still premium – or at least affordable premium) JBL PartyBox speaker systems have pretty similar features, with excellent light shows, basic but highly useful mixing, and both digital and analog music inputs, and they all have the cool retractable handle and wheels design that makes them look like a party looking for a place to happen.

The JBL PartyBox 710 is the biggest, at about 3 feet tall and weighing in at just over 60 pounds, and its main advantage is bass – really deep, powerful bass that offers intense slam and really, really gets people moving.

The JBL Partybox 310 is still pretty darn big – over 2 feet tall and about 42 pounds – and while it may plumb the depths of the 710 it still has thundering bass, much deeper, faster, and more powerful, in fact, than anything else I’ve heard in this range.

Even the JBL PartyBox 110, which is about the same size as the 310 but about half the weight, has amazingly strong, deep, and well-controlled bass, and makes a commanding presence at any party.

And since they’re all JBL products, they all have not just slamming bass, but clear, relaxed mids and highs and a beautiful sound overall – dynamic, musical, and a ton of fun. They also all have stereo pairing (in case one just isn’t loud enough), a great splashproof rating and really tough and durable construction, the best tech, and the best long-term reliability.

So you can really choose mostly on your budget – any one of the JBL PartyBox portable Bluetooth speakers will play intensely loud, and whichever one you choose you (and your party guests) will be thrilled!

Superb Quality, Superb Sound, and Slamming Bass!

I love Ultimate Ears Bluetooth speakers – not just because they play really, really loud, but because they are just beautiful products, so pleasing in how they look and how they work.

But I mostly love Ultimate Ears because of their sound – loud, yes, and in fact, this appropriately named Hyperboom is rated conservatively at 100 decibels maximum sound pressure.

But here we are at a level where something else, and something very important, happens – not only is the Hyperboom loud, it has incredibly dynamic sound, with real musical energy and energetic gradations even at the highest volume.

This dynamic quality makes the music seem even louder and makes everything much more impressive and engaging, and when you factor in the incredibly low distortion, the rich and accurate tonal quality, the intense deep bass, clear and present mids, and shimmering highs, and the enormously spacious and transparent sound overall, the Ultimate Ears Hyperboom is one of the finest sounding Bluetooth speakers on the planet.

Not the most expensive, but definitely one of the best. And one of the loudest, on paper and especially in practice.

The Hyperboom is also a superbly crafted product, with a beautiful premium fit and finish, great battery life, latest generation Bluetooth, fantastically clever and effective adaptive equalization (which actually reads a room’s acoustics to always provide optimal sound), excellent connectivity, and a lot more.

Plus it might have the coolest name of any audio product going!

The Ultimate Ears Hyperboom is not just one of the loudest Bluetooth wireless speakers on the market today, it is one of the finest, and is very strongly recommended.

And while the Hyperboom is quite affordable for what it offers, it is still in that affordable premium range that may be out of reach for many of us, so for similar overall quality, and still awesome maximum volume, you might also want to consider the amazingly affordable Ultimate Ears Megaboom 3 or the downright cheap and wonderfully wee Ultimate Ears Boom 3.

My Favorite Super-Loud Portable Bluetooth Speaker

Just How Loud?

  • Power: 160 Watts
  • Spl: 101 Decibels

Ok, not just my favorite – the JBL Boombox 2 is one of the most popular and highly rated portable Bluetooth speakers made, and is fiercely loved by anybody lucky enough to have one.

The manufacturer’s specifications for maximum sound pressure level on the Boombox 2 – 101 decibels – is definitely high enough to qualify it for this elite group, and make it one of the loudest Bluetooth speakers you can get.

But this is a JBL, so the specifications are only part of the reality. In actual listening, you notice right away that the Boombox 2 is a bit intense, with a thrillingly punchy and energized quality rarely heard at this level.

Sure, it has that JBL bass – amazingly deep and strong for its size, in fact – and that’s part of it, but all the way up and down the JBL Boombox is so dynamic, so captivating, and at the highest volumes it can be almost overwhelming.

Don’t be afraid, though – again, this is JBL gear, so no matter how ‘intense’ or ‘overwhelming’ the Boombox is in terms of volume, it is also wonderfully musical, with warmth, presence, clarity and superb spatial projection, very low distortion and surprisingly high fidelity.

In fact, this is why the JBL Boombox 2 is my favorite – in addition to the intense volume and the amazing bass (not to mention fantastic battery life, the latest Bluetooth, the best tech overall, true waterproofing and that legendary JBL build quality and reliability) the Boombox 2 is a beautiful sounding speaker.

I also love the Anker Soundcore Rave portable Bluetooth speaker, which – at around the same price as the JBL and with an astonishing 107 decibels maximum loudness – is definitely worth mentioning here, and which has a beautiful sound, great tech, and excellent overall quality. I might prefer the JBL, but tons of people love the look and sound of the Rave, and it is a bit louder.

Loudest Bluetooth Portable Speaker – Affordable Premium

Just How Loud?

  • Power: 85 Watts
  • Spl: 120 Decibels

As wonderful as the Ultimate Ears and JBL speakers above are, sometimes you just want raw power, and it doesn’t get much more raw and powerful than the Turtlebox!

A bit ugly, built like a tank, as waterproof as it gets, and louder than anything save the ridiculous Soundboks at the top of our list, the generation 2 Turtblebox is a bit of a legend among partiers and music lovers who want the ultimate intensity.

No, the Turtlebox gen 2 may not have the refinement of the Hyperboom, or the amazingly appealing sound of the JBL, but that’s really a matter of opinion, and so many customers think the turtle is better sounding.

I’ve spent a lot of time with all three and am a bit of an audiophile snob I would probably opt for the UE for tonal beauty and the JBL for accuracy and the most appealing sound signature, but I have to say that the nearly indestructible beast that is the Turtlebox has remarkably warm, clear and exciting sound, with a bracingly bright quality, tons of strong, extended bass and amazingly transparent and spacious presentation.

In fact, if you’re looking for a portable Bluetooth speaker primarily for outdoor use, I would say the Turtlebox is the best sounding in that environment, and the best choice – with its special outdoor tuning and its astonishing maximum volume, it can fill a large, open space far better than anything else at this level.

With an intelligent and highly usable design, superior build quality and amazing toughness, the best tech, and great battery life – even at max volume – the Turtlebox gen 2 is quite possibly the best outdoor portable Bluetooth speaker you can get, and it is definitely, and without any serious competition, the loudest.

Loudest Bluetooth Portable Speaker – Mid-Priced

Just How Loud?

  • Power: 85 Watts
  • Spl: 100 Decibels

I guess that ultimately I’m not too worried about which Bluetooth speaker you end up buying, as long as it plays really loud, it meets your needs and you love it.

But let me just say that if this sort of affordable-premium sub-300 dollar range fits your budget, just get the Tribit StormBox Blast and be done with it.

This is a very special and loveable speaker, which has about the highest customer ratings of any product of its type and is constantly recommended by pretty much anybody who has one.

Not only can the Tribit StormBox boast prodigious maximum volume – really, even louder than the 100-decibel manufacturer’s specifications might indicate – it is a fantastic sounding speaker, with big, bold, and super-engaging sound, and an amazing combination of real musical warmth and richness and startling clarity and detail.

One of the most accurate speakers on this list, the StormBox does not have that hyper-popular hyper-boost in the bass most portable Bluetooth speakers employ, nor does it resort to artificial enhancements of dynamic energy or spatial imaging.

Instead, the Tribit is very well-balanced and very neutral, and lets the music speak for itself, Despite this – or maybe because of this – the StormBox Blast has absolutely incredible bass for its size – deep, fast, and well-controlled – as well as superior stereo imaging and sound projection and the best and most exciting portrayal of musical energy and dynamics in its class.

But if you’re a bass head just turn on the XBass and you’ll be more than happy!

It’s really rare that an affordable speaker can be so accurate and neutral and yet appeal to so many people and enjoy such huge sales figures, but again this Tribits StormBox Blast is a very special speaker. I’m not even getting into its superb material and build quality, its superior tech, or its brilliant design, but just based on the Blast’s intense volume and beautiful sound it definitely deserves my highest recommendation.

Loudest Bluetooth Portable Speaker – Budget

Just How Loud?

  • Power: 70 Watts
  • Spl: >100 Decibels

I am so happy that I found and got to spend some time with the W-King 70-watt Bluetooth portable speaker before I wrote this article – otherwise, I’m really not sure I could have come up with a really great and truly recommendable super-loud Bluetooth speaker at this budget level.

But the W-King is definitely all that – super-loud, with fantastic sound even at maximum volume, and without a bit of strain. In fact, like some of the more expensive choices on this list (and as a sign of real quality) even when the W-King is fully cranked, it still has real range – not just loud, but still extremely dynamic, punchy and expressive in sound even at full volume.

The bass is not as deep as something like the JBL Boombox 2 (which, to be fair, is almost 4 times the price), but the D10 still goes quite deep and has a nicely boosted quality which adds exciting foundation but never overwhelms the upper frequencies. Mids and high frequencies are surprisingly refined, accurate, open and detailed, and really lovely in sound.

I would have to say that just based on sound quality, and the enormous volume it can crank out, the W-King D10 is an easy recommendation, but it just gets better and better. Build quality rivals almost anything on this list, and the D10 has a remarkably substantial feel. The features and technology are also as good as it gets, with 5.3 Bluetooth, real stereo speaker configuration, an astonishing 42 hours maximum battery life, IPX6 waterproofing, a microphone input for karaoke, auxiliary input, and a memory card slot, even an LED light show.

Ok, truth be told I’m not crazy about the lights, but thankfully they can be turned off.

But, lights aside, it’s all good – really an amazing product for the money, the W-King D10 70-watt stereo speaker system is not only one of the loudest budget-priced Bluetooth portable speakers you can get, but it might also be the best overall.

I’d also like to mention the W-King D9 60-watt Bluetooth speaker, which is about thirty dollars less than the already super affordable D10 – it doesn’t get quite as loud, but definitely can blast with the best of them, and is also a very advanced and high-quality unit and well worth considering.

Loudest Ultra-Compact Bluetooth Speaker

Just How Loud?

  • Power: 4.2 Watts
  • Spl: 80 Decibels

To close this buyer’s guide for the loudest Bluetooth portable speakers, I’m going to sneak in the wee JBL Go 3.

I say ‘sneak in’ not because this darling little guy is small enough to sneak in anywhere, but because he doesn’t quite qualify – he falls short of our admittedly extreme 100-decibel threshold by a full 20 decibels!

But I have to say that for a speaker this size the JBL Go 3 has amazingly strong sound – big, surprisingly bassy, clear, open and very well projected, and really dynamic and powerful.

The Go 3 also holds together beautifully even at that highest volume, with no strain and very low distortion – some ultra-small and ultra-affordable Bluetooth speakers will play as loud as the JBL, and may sound even louder due to their distortion and harshness, but absolutely nothing else I’ve ever heard at this level will play so loud and sound so good.

Other than that there’s not much to the JBL Go 3 – just a very basic Bluetooth portable speaker with good battery life, superior dust- and waterproofing and an incredibly tough and durable JBL build quality. Even at regular volumes, this is my favorite ultra-portable, and IMHO the best you can get, but when really cranked it is a little bit awesome!
