1 The New SOUNDBOKS – Best Premium Loudest Portable Bluetooth Speaker
The loudest Bluetooth speaker currently available is undoubtedly the New SOUNDBOKS 3rd generation. It’s a bit of a stretch calling this speaker portable as it weighs a whopping 33 pounds and stands 31.5 inches tall. But hey, there are handles on the side, and it’s moveable, so it makes the list.
Looking to throw a 3-day party, and you need a portable Bluetooth speaker that will comfortably rock the joint? This one of the best Bluetooth party speakers you can buy. This absolute monster can pump out a whopping 126dB at full volume.
A full charge will also last an impressive 40 hours, and a spare battery comes as part of the package. That’s potentially 80 hours of continuous playback, more if you can charge the spare. Therefore, this is one of the best battery life portable Bluetooth speakers as well.
We’re talking old-school simplicity. It’s an imposing look with a mesh grille protecting the huge 10” woofers and 1” tweeter that produce the boom. Internally, three amplifiers drive the show, producing a remarkable 216 watts of power.
Not only is this speaker insanely loud, but it also manages to produce a distortion-free and very pleasing sound profile. You’d expect a speaker of this size to be a bass-boomer. However, it’s a surprisingly neutral sound signature that allows the whole frequency range to shine. It has a tight and punchy bass that never overwhelms the show.
Connectivity options are also impressive…
On top of the Bluetooth, there are 3.5mm auxiliary and XLR sockets. Up to five Soundboks speakers can be connected for a truly earth-shaking experience.
All of this raw power and rugged good looks don’t come cheap, though. This is the most expensive speaker on our list by some distance, so bargain hunters will probably be scared off. But if you’re willing to stump up the cash, then you’ll have an incredible speaker with a host of awesome features that put the New Soundboks in a league of its own.
- Immense distortion-free sound.
- A well-balanced, neutral sound profile.
- Ridiculous battery life.
- Classic design.
- It’s not cheap.
- Portable but too heavy to carry long distances.
2 Marshall Woburn II – Best Indoor Loudest Portable Bluetooth Speaker
More famous for their amplifier range, Marshall has been diversifying into the home speaker arena in recent years. With the Marshall Woburn II, they’ve brought their classic guitar amp design and created a ferociously loud Bluetooth speaker that lives up to their rock ‘n’ roll heritage.
Let’s have a party!
A full 110dB of perfectly undistorted sound is delivered by dual 5.25-inch subwoofers and two tweeters, powered by class D amps which deliver 120 watts of output. Yes, there’s enough volume here to sustain the rowdiest of parties.
Fortunately, the Marshall Woburn II maintains a high level of detail and clarity even with the volume cranked up to ’11’. Bass has a thumping yet tight delivery, and vocals and instruments have all the space needed to hold their own.
If you love that classic Marshall look…
You know, the one harking back to the golden age of rock, you’ll adore the Woburn II’s aesthetics. If you’re looking for a subtle speaker that will blend into the surroundings, this ain’t it. The Woburn II is positively begging to be seen, and rightly so. Personally speaking, this is exactly how a speaker should look.
Again, this speaker is on the heavier side of portability, weighing 17.5 pounds, and there isn’t any kind of handle or strap to carry it around. It’s also not water-resistant in any way, so you’ll want to be careful if taking the Woburn II outside. You’ll need to be near an electrical socket if you do venture outside as it’s not battery-powered.
Expensive, but worth it…
It’s also relatively expensive compared to some of the speakers on this list. But it’s still under half the price of the SOUNDBOKS, and for my money, it’s worth every cent.

- Rock ‘n’ roll aesthetics.
- Super loud.
- High clarity across the frequencies.
- No smart features.
- Quite heavy.
3 Bose S1 Pro – Most Versatile Loud Portable Bluetooth Speaker
On to another relatively expensive high-end model, the Bose S1 Pro is not quite as loud as the two previous mentions on this list but still packs one hell of a punch. Full volume delivers an impressive 109dB, powered by 150 watts of output, guaranteed to blow your socks off.
Volume does not come at the expense of sound quality…
That classic Bose sound signature is present, providing a well-balanced listening experience and possibly the cleanest sound of any speaker on this list. Bass-heads might be a little underwhelmed at the lack of thump.
But as any HiFi fan will know, Bose products always lean towards a more neutral sound profile. This is, so it reproduces music as it was recorded. As a result, this is one of the best sounding loud portable Bluetooth speakers available.
The Bose S1 Pro is also a feature-laden speaker with a load of high-tech extras included. For example, built-in sensors that change the directional sound output ensure that wherever you position this speaker in a room. You’ll have top-quality sound.
On top of the Bluetooth connectivity, two XLR ¼-inch jacks can be used for instrument or microphone connections. There’s also a 3.5mm auxiliary port for any other device you may want to use.
On the downside, battery life is unexceptional, with 11 hours on a full charge. It’s also pretty heavy, weighing in at 15.5 pounds. It’s a sturdy build, and even at that weight, it is portable enough to transport wherever need be.
Built to entertain…
All of this high-tech awesomeness doesn’t come cheap, though. The Bose S1 Pro is 20% more expensive than the Marshall Woburn but delivers a lot more in the way of features and connection options. Need a fully-featured speaker capable of entertaining up to 100 people? The Bose S1 Pro is more than up to the task.
- High-tech features.
- Loud, crystal clear sound.
- Multiple connection options.
- Sleek, practical design.
- Unimpressive battery life.
- Portable but quite heavy.
4 Aiwa Exos-9 – Best Bass Heavy Loudest Portable Bluetooth Speaker
Dropping down the price scale is the Aiwa Exos-9. Whilst not quite as loud as the previously mentioned models, it’s still one of the loudest you can buy. The Exos-9 packs an impressive five drivers to deliver 100dB of sweet sounds with 200 watts of amplification, ideal for use outside.
Bass-heads will be more than satisfied…
The 6.5” subwoofer driver is capable of producing a seriously pumping and distortion-free bass. That’s ideal for showcasing hip-hop and as one of the best portable Bluetooth speakers for EDM. While it features a bass-driven sound profile, the mids and highs are not lost in the mix.
Vocals and instruments come through loud and clear. Likewise, a 5-band EQ allows for a decent level of fine-tuning to achieve the desired sound of your choice.
The Exos-9 has a slick modern design with a large front grille and a beautifully styled touch control panel sitting on top. Battery life isn’t the best at only nine hours. But, you can purchase extra battery packs direct from Aiwa that will ensure there’s enough juice to keep the party going.
Portability is reasonably good…
Although it’s not particularly light at 13 pounds, there’s an extendable handle on the back which makes it easy to transport. One downside is the lack of any water resistance. Although you’re unlikely to be using the Epos-9 outside in wet weather, you’ll have to take care if using it anywhere near a pool.
Connection options are also nothing to write home about. You’re limited to Bluetooth or a 3.5mm auxiliary port. On the plus side, you can pair another Exos-9 through a speaker link feature for a truly powerful experience.
Excellent affordable value…
All in all, the Aiwa Epos-9 is a genuine beast and, while not the most feature-laden speaker on this list, offers outstanding value for money and is certainly one of the most enjoyable and loudest portable Bluetooth speakers you can buy.
- Powerful bass-driven sound.
- 200-watt output – excellent for outdoors.
- Excellent value.
- Stylish aesthetics.
- Limited connection options.
- No water resistance.
5 Turtlebox – Best Outdoor Loudest Portable Bluetooth Speaker
Just one look at the Turtlebox portable Bluetooth speaker is enough to know that this is a rugged outdoor model designed to stand up to anything nature can throw at it. It also gets seriously loud, throwing out an unbelievable 120dB of bone-shaking sound.
Small but mighty…
Considering its diminutive size and relatively lightweight (8 pounds), this is an impressive level of output. It’s far and away, the loudest Bluetooth speaker for its size. Additionally, it’s also one of the best lightweight loud portable Bluetooth speakers around.
The hard-case outer shell provides an outstanding level of shockproof protection from knocks and drops. It also comes with an IP67 rating. So, it’s one of the best waterproof loud portable Bluetooth speakers on the market. You’d be hard-pushed to find a more robust Bluetooth speaker than this.
How does it sound?
For such a small speaker, the sound quality on offer is impressive. Crank her up to full volume, and the Turtlebox takes it in full stride with almost zero distortion.
Rich and punchy lows are complimented by nicely balanced and detailed mids and treble. The sound profile was put together with the outdoors in mind, to cut through the wind and ambient noise. It does a great job of this.
Made for the outdoors…
A full 24 hours of battery life at full volume and almost 50 hours at half volume adds a lot to an already attractive package. Connections are limited to Bluetooth and the obligatory 3.5mm auxiliary port. But that feels more in keeping with the kind of speaker you’d take on a 3-day camping trip. So that can be forgiven.
Whilst the rugged design may not be for everyone; the Turtlebox makes an outstandingly loud portable Bluetooth speaker for any kind of outdoor activity. As an addition to your living room, most people will want something with a slightly more refined look.
- Impressively loud for its size.
- Rugged build quality.
- IP67 rating.
- Top-level battery life.
- Very portable.
- Won’t look so great in your home.
- Lack of EQ adjustability.
6 JBL Xtreme 2 – Best Selling Loudest Portable Bluetooth Speaker
Dropping down in size but still packing a firm punch, we have the JBL Xtreme 2. This has been a best seller for a few years now, and for good reason. Whilst far from the smallest portable speaker out there, the Xtreme 2 can be stashed in any rucksack, or you can sling it over your shoulder using the accompanying strap.
Very impressive for its size…
Despite only weighing just over five pounds, it’s capable of reaching a respectable 85dB at full volume. Two 70mm full-range drivers and two 20mm tweeters do the hard graft, providing 40 watts of output. Sound quality is geared more towards a mass-market appeal.
A surprisingly powerful bass leads the way, and while excitingly thumping, slightly oversteps into the mids, which could do with a little more space. Trebles are crisp enough, though. Whilst it’s a fun and very loud presentation, audiophiles will not be blown away. That said, the average consumer will find it pleasing enough.
The JBL Xtreme has a respectable 15-hour battery life, and the standard rubberized mesh provides a decent level of protection from the rough and tumble of daily life. An IPX7 rating means the Xtreme can be submerged in shallow water for up to half an hour with no ill effects.
The only other connection option aside from Bluetooth is the 3.5mm port. However, you can connect up to three Bluetooth devices at the same time. This is a nice option if there’s more than one budding DJ in your circle of friends.
Small and loud…
The JBL Xtreme is a good all-arounder. If you’re after a decently loud portable Bluetooth speaker that won’t look out of place in your home and is a capable outdoor performer, the Xtreme is worth a look. Mind you, it’s not cheap, and we think there’s far better value to be had from some of the other speakers featured here.
- Truly portable.
- IPX7 rating.
- Hardy construction.
- Suitable for the home and the great outdoors.
- Slightly too much bass.
- Questionable value.
7 Ultimate Ears MEGABOOM 3 – Best Compact Portable Bluetooth Speaker
Dropping significantly down the price scale, the Ultimate Ears MEGABOOM 3 is by far the smallest speaker on our list. This little stick of dynamite can produce an incredibly loud sound despite its diminutive proportions. At full volume, it’s capable of 98dB with a power output of 36 watts. Staggering for one so small.
Plenty of punch…
The cylindrical design, roughly the size of two Coke cans, has drivers mounted on both sides, delivering a 360-degree sound. The sound quality is also pleasantly surprising. Bass has a decent amount of punch, more so than any other speaker its size.
There’s also nice clarity in the mids and treble frequencies that comes through well despite the focus on bass. Audiophile speakers these are not, but it’s a fun profile full of energy that’s more than loud enough to keep a small party entertained.
A 20-hour battery life…
This outperforms some of our more expensive loudest portable Bluetooth speakers. Portability is also top-notch. Weighing just 2.9 pounds and with a shape that will fit easily into any rucksack, you can take the MEGABOOM 3 just about anywhere. Even underwater if you like, thanks to the IPX7 waterproof rating.
There are a few other snazzy features worth mentioning. You can daisy chain up to eight MEGABOOM’s together if you want to pump up the volume. You can also pair two Bluetooth devices at the same time, and the MEGABOOM will remember up to eight different devices, which will pair automatically.
A great choice for Alexa…
The Ultimate Ears app also allows a good degree of EQ adjustability. Furthermore, this is one of the best Alexa enabled portable Bluetooth speakers you can find. All in all, there’s very little to complain about this competitively priced speaker. The Ultimate Ears MEGABOOM 3 delivers loudness and usability in spades.

- Distortion-free boom.
- Bass-centric but fun profile.
- 20-hour battery life.
- Very affordable.
- Not ideal for large parties.
8 AOMAIS GO – Best Budget Portable Bluetooth Speaker
Finally, if you still require as loud a sound as possible but have a limited budget, the Aomais Go could be the portable Bluetooth speaker for you. At a fraction of the cost of the models previously featured, this relatively lightweight model pumps out an impressive 98dB, with a power output of 30 watts.
A superb choice for those on a budget…
At such a low price, you’re don’t get the kind of audio quality seen elsewhere. But it’s a respectable effort all the same. The sound profile is based primarily around the mid-ranges, with vocals and lead instrumentation to the fore.
Despite the loudness of the Aomais Go, bass response is somewhat lacking. Bass-heads steer clear of this one. Treble response is clean and crisp enough, though, to make for a reasonably enjoyable listening experience.
Built to be on the go…
The Aomais Go is one of the most portable models on this list. The built-in handle and lightweight design (4 pounds) make this a breeze to carry around. An IPX7 rating means you don’t have to worry about rain or dirt damaging the speaker. Apparently, the Aomais Go will even survive a mud bath.
Excellent battery life of 30 hours adds a lot of value to such a cheap speaker. It makes you question why models, many times the price, can only manage a fraction of this. The Go also has a built-in microphone to handle calls. The quality isn’t great, but it’s handy if you don’t want to cut your phone’s Bluetooth connection.
If loudness on a budget is your main requirement, the Aomais Go has to be the loudest portable Bluetooth speaker under $100 and is definitely worth a look.
- Incredibly cheap.
- IPX7 rating.
- Long-lasting battery.
- Uninspiring sound quality.
- Rather ugly design.
Loudest Portable Bluetooth Speakers Buying Guide
When looking to buy the loudest portable Bluetooth speaker, you’ll need to understand the terminology used when discussing power and loudness.
Sound Pressure Level
When trying to discover the volume output of a speaker, we need to look at the SPL (Sound Pressure Level), which is measured in decibels (dB). This is also known as speaker sensitivity.
The output dB SPL has to be driven by power which is referred to as wattage. The higher the wattage, the more amplification the speaker will have. To gauge the overall loudness of a speaker, you need to look at the RMS (continuous power output) wattage rating together with how many decibels it can take.
Also, make sure you are looking at the RMS wattage rating, which indicates how much continuous power a speaker can output. Rather than the peak wattage, which indicates the peak power a speaker can handle in short bursts.
More Decibels = Higher Volume
The higher the decibel value, the more volume the speaker is capable of. Decibel measurements are worked out on a logarithmic scale. This means an increase of 10 decibels makes the sound ten times louder. For example, a 100dB speaker is actually ten times louder than one with a rating of 90dB.
What is considered a safe level?
Prolonged exposure to noise over 70dB may harm your hearing. Whereas any noise in the 120dB range can have serious long-term consequences for your hearing.
All of our featured speakers well exceed 70dB. It’s important to be aware of the potential damage you may be exposing yourself to when making your purchase. And never listen to excessively loud music at a short range for lengthy periods.
What will you be mainly using your speaker for?
Do you host lots of outdoor parties attended by many people? Then you’ll need a speaker with a lot more oomph than if you’re listening by yourself or with a few friends. Work out your needs and buy accordingly.
