For a big sound with maximum portability, the JBL Boombox 2 fits the bill nicely and will continue to rock out for 24 hours without needing a power boost. JBL have upped the Bluetooth to 5.1 from the original model and it can also hook up with other JBL PartyBoost devices. Available in a variety of colours, the JBL Boombox 2 is an easy recommend for those looking to take the big sounds with them.

3. Marshall Woburn II
When it comes to iconic branding in the world of amps and speakers, Marshall's classy designs are hard to beat.

4. Amazon Echo Studio
At first glance, you might not think an Amazon product could deliver the kind of thunderous noise associated with the loudest Bluetooth speakers in our list, but you'd be wrong. The Amazon Echo Studio can pump out a whopping 90dB of sound. As you'd expect with a smart speaker, it comes with loads of bells and whistles to tinker with including Alexa voice assistant and comes highly recommended.

5. Sony SRS-XB33
At Louder, we're well aware of Sony's range of excellent headphones, and they're no slough when it comes to speakers. The portable SRS-XB33 isn't too bulky but it delivers rich bass and should be on your shopping list if this sounds like your jam. Being a portable speaker, it's also waterproof and dustproof so is a neat choice for those looking to take their sounds to a party.

6. Sonos Move
While the Sonos Move is a great option for portability, it's also a speaker that's comfortable in your living room or bedroom thank to its sturdy design and powerful audio. It can hook up with Google Home which is perfect for those who just want a single speaker in their flat, while its ability to crank out 85 db will keep the party going. Bass is a little lacking but aside from that, the Sonos Move is a solid option.

One of the loudest Bluetooth speakers gets a thunderous upgrade

Dimensions: 66 x 43 x 32cm (25.6 x 17 x 13 inches)

+ As loud as the front row at a concert 40-hour charge
Reasons to avoid
- Weighs in at a heavy 15.4kg
At a glance
✅ Buy if you want a massive-sounding speaker: With up to 126dB of earth-shaking audio and top battery life, these SoundBoks truly deliver.
❌ Avoid if you're after a more lightweight model: Weighing in at 15.4kg, you might be after something lighter.
The third generation of SoundBoks' huge-sounding speaker range delivers yet another sonic assault on the senses. It delivers a whopping 126dB of sound, which is delivered thanks to two 10-inch 96dB woofers and a 104dB compression driver tweeter. In other words, it’s loud.
The SoundBoks (Gen 3) matches the excellent 40 hours of battery from the last model at mid-volume, and it can be connected to your smartphone or tablet through Bluetooth 5.0. While it’s classed as a portable speaker, it’s still a heavy thing to lug around as it weighs in at a considerable 34lbs. But the good news is it features IP65 tech, so it’ll cope with rain and dust with no problems.
Sure, it’s not the most stylish of speakers on the market, but to make it a little easier on the eye, SoundBox offer customers a choice of grill colours: Black, white, orange, blue and red. And really, when it’s cranking out your favourite sounds at a thunderous volume, who really cares what it looks like?

Best for portability
2. JBL Boombox 2
JBL give their much-loved audio monster a makeover
Specifications
Loudness: 101 dB
Frequency Response: 50Hz-20kHz
Audio Output: 2 x 40 W RMS-woofer + 2 x 40 W RMS-tweeter
Dimensions: 48.5 x 20.1 x 25.7cm (19.1 x 7.9 x 10.1in)
Weight: 5.9 kg (13 lbs)
Audio: 4-inch woofer x 2, 20mm Tweeter x2
Battery Life: 24 hours
Features: Bluetooth 5.1, IPX7 waterproofing
Reasons to buy
+ Massive volume 24-hour battery life Completely waterproof
Reasons to avoid
- You may not like the boombox aesthetic - even with its updated new look
At a glance
✅ Buy if you want a big-sounding, waterproof speaker: This is made to be taken to parties and with 24 hours of battery and completely waterproof, it's a top option.
❌ Avoid if you're after something you're planning on using indoors : The design might be a bit old school for some tastes and won't suit all interior spaces.
The JBL Boombox 2 is a step up from the original model and remarkably, it delivers an more solid sonic punch. The US audio experts call it “the loudest JBL boombox ever” so there you have it.
So what are the differences between the JBL Boombox and this model? For starters, Bluetooth 4.2 has been replaced with Bluetooth 5.1 and can connect with JBL PartyBoost-compatible devices. The audio output has been increased and now boasts an additional RMS-woofer and 2 x 40 W RMS-tweeter and the unit has undergone a design update. It's a smidgen heavier but you’ll still get 24 hours of playtime on a single charge and like its older sibling, it’s completely waterproof thanks to IPX7 tech.
This robust bit of kit is available in black or camo and is well worth a look if you’re in he market for something that’ll shake your foundations.

3. Marshall Woburn II
The classiest Bluetooth speaker here
Specifications
Loudness: 110 dB
Frequency Response: 30–20,000 Hz
Audio Output: 110W
Dimensions: 400 x 310 x 200 mm (15.75 x 12.20 x 7.87 In)

Reasons to buy
+ Classic design from a legacy amp maker RCA and stereo jack for analog listening Three channel control via an app or manually on the speaker’s panel
Reasons to avoid
- Nothing-proof – keep away from bad weather and splashes of any kind
At a glance
✅ Buy if you're a Marshall fan looking for a powerful speaker: All Marshall speakers look the business, but the Woburn II is our pick if you want LOUD!
❌ Avoid if you're after a portable solution: The Woburn II is strictly for indoor use only.
Historic brand Marshall has been loyal to loud for decades. Fortunately, this old-timer seems quick to adapt to the modern times when you consider the Woburn II’s Bluetooth connectivity. Other additions include a Marshall app which gives you the ability to turn the speaker on and off, as well as manually control the volume, bass and treble.
The speaker offers great overall sound and was built to sustain clear, low frequencies thanks to its two subwoofers duelled with a bass reflex system and external port.
Although this Marshall Bluetooth speaker is low fuss, it is high maintenance considering it's not waterproof, dirt-proof, beer-proof… so keep this inside and away from spillage.

Best for sound quality
4. Amazon Echo Studio
The best smart Bluetooth speaker for overall sound quality
Specifications
Loudness: 90 dB
Frequency Response: 30Hz to 24kHz
Audio Output: 330W
Dimensions: 206 mm tall x 175 mm diameter (8.1 inches tall x 6.9 inches diameter)
Weight: 3.5 kg (7.7 lb)
Audio: 1" tweeter, three 2" mid-range speakers, and 5.25" woofer
Battery Life: n/a
Features: 3.5 mm, mini-optical Toslink line in, Zigbee smart home, Alexa app, Fire TV compat, FLAC, MP3, AAC, Opus, Vorbis, Dolby Digital, Dolby Digital Plus, Dolby Atmos, Sony 360 Reality Audio/MPEG-H support
Reasons to buy
+ Voice-controlled with Alexa Room acoustic analysis for custom sound
Reasons to avoid
- Not portable
At a glance
✅ Buy for voice controlled convenience: All Amazon speakers have Alexa integration - and the Echo Studio has the added bonus of 90 dB of audio delivery.
❌ Avoid if you're after a pro-level speaker: The Echo Studio does a lot of things right, but if you're after a dedicated music speaker, there are other options available.
At 65% of the market share, it feels like everyone and your mum has an Amazon Echo. But when it comes to smart speakers, “loud” isn’t the first thing that comes to mind? In this case, delivering up to 90dB of sound – as loud as a revved-up lawn mower – the Echo Studio does a very good job of shaking that notion.
It’s unlike other conventional Bluetooth speakers due to the positioning of its five speakers: there's a midrange speaker directed upwards, a midrange speaker facing to the right and another to the left, a tweeter directed forward, and a woofer directed downwards towards the hollowed-out space which Amazon calls the bass aperture. These placements are meant to give listeners an immersive experience – as if you are surrounded by sound.
As a smart home device, users get the perks of software updates, plus the ability to connect to a whole host of other smart home devices. It’s worth noting that this speaker is designed for use within a home setting, not for outdoor use.
All in all, the Amazon Echo Studio may not be the choice for someone looking for a pro-level speaker, however it is a great speaker for someone who wants an all-in-one device with great audio.

Best for heavy bass
5. Sony SRS-XB33
A portable Bluetooth speaker that’s all about the bass
Specifications
Loudness: Not stated
Frequency Response: 20Hz – 20kHz
Dimensions: 246 x 97 x 106 mm (11.5 x 6.5 x 8.75 inches)
Weight: 1.1 kg (8 lb)
Audio: X-Balanced speaker unit
Battery Life: 24 hours
Features: IP67 waterproof and dust-proof
Reasons to buy
+ Portable Good value Great sound
Reasons to avoid
- Battery life could be better
At a glance
✅ Buy if you're looking for extra bass: This another excellent portable speaker and comes highly recommended if you're after some beefy bass.
❌ Avoid if you don't want something flashy: The Sony SRS-XB33 is a neat portable speaker - just bear in mind it also has inbuilt disco lights!
Sony has always been a brand you can trust in the audio field, and the Sony SRS-XB33 continues this heritage with a portable, dust-proof, waterproof speaker that delivers a superb sound thanks to its unique internal speaker layout.
We liked the quirky fact that you can chain up to 100 of these together, not that we can see a situation where that would ever happen but it’s a nice idea which conjures images of an all-out sonic attack.
Despite its relative size, however, we were impressed with the depth and thud that came from bass and low-end sounds, and can vouch for its volume levels which retain clarity even when you push it to its limit. We could take or leave the flashing disco lights though.

6. Sonos Move
The best portable smart speaker
Specifications

Frequency Response: n/a
Audio Output: n/a
Dimensions: 240 x 160 x 126 mm (9.44 x 6.29 x 4.96 inches)

Audio: one tweeter, one 3.5 inch mid-woofer
Battery Life: 10 hours
Features: IP56 water and dust resistance, supports WiFi 802.11, Apple AirPlay 2, Bluetooth connectivity
Reasons to buy
+ Bluetooth, WiFi connected and voice activated Portable Weather proof with a shock-resistant case
Reasons to avoid
- Not the best bass
At a glance
✅ Buy if design matters: Some of the speakers featured here might be an acquired taste when it comes to design, but the Sonos Move looks and sounds the business.
❌ Avoid if you want portable power : The Sonos will take care of all your indoor audio needs - just don't think about taking it outside.
Times have changed for Sonos with this, their first portable Bluetooth speaker, dubbed ‘Move’.
The difference between this and older models is it’s portability and built-in intelligence. Integration with Google Home and Amazon Echo gives users the ability to use it like any other smart speaker. Plus, all that portability comes complete with resistance to the elements, meaning you can take this speaker outside with confidence.
Although it is plenty loud 85 db – somewhere between a really loud blender and a lawn mower – there is a downside. The Sonos Move includes everything but a subwoofer, a loudspeaker that’s key to bringing out the lowest bass tones in a song.
It’s definitely loud and great for the average listener, but missing the deep low-end may be a deal breaker for some.

Loudest Bluetooth speakers: Buying advice
What makes a speaker 'loud'?
First, check out how many decibels (dB) a speaker cranks out, or look at the scaled measurement of the intensity of sound. Not unlike an earthquake, the higher up on a scale, the more exponentially powerful the sound is.
Every 10 dB represents a 10-fold increase – or doubling – in volume. For example, 20dB is 10 times louder than 10 dB, while 30 dB is 100x louder than 10 dB and - with that logic in mind - 1,000x more powerful than 0 dB. For reference, the average concert has an intensity of about 100 dB.
Now let’s talk about Wattage (W) – because all that sound needs to be backed by sheer power. But how many watts do you really need? Every speaker is set at its own wattage, telling us exactly the strength of its perceived amplification. However, a 100W speaker isn’t twice as loud as a 50W speaker, but rather 3dB louder.
Loudest Bluetooth speakers: size and aesthetics
You can trust Louder Our experienced team has worked for some of the biggest brands in music. From testing headphones to reviewing albums, our experts aim to create reviews you can trust. Find out more about how we review.
Of course, this is all well and good but you'll also have to take into consideration how the speaker will look in your living room, music study or outdoor space. Some of the loudest Bluetooth speakers can, it has to be said, be a little on the plain side, with the majority of the energy involved going into how the blasted thing sounds. Fair enough!
Some speakers like the SoundBoks (Gen 3) are big and bulky, while the Marshall Woburn II is emblazoned with the audio giant's instantly recognisable label. These won't be a natural fit in some environments. Others like the JBL Boombox 2 hark back to the good old days of the humble ghetto blaster – minus the double tape deck and radio dial – while the Anker Soundcore Rave comes with flashing bells and whistles making it an ideal choice for those who like to party hard.
Now that you know what you’re looking for, you're ready to peruse our guide to the victors of volume, the number ones of noise... the loudest Bluetooth speakers around. Our price comparison widgets have found the best prices online right now for you, too. Just hit the 'product guide' tab to check out our list.
Protecting your ears
How can I protect my ears?
We wouldn’t be a responsible rock site if we didn’t include a word on long-term exposure to excessive volume. While we’re big supporters of playing things loud, it’s possible to cause permanent damage to your ears if you’re always cranking it (don’t believe us, Metal Hammer deputy editor Eleanor Goodman told us what it’s like living with Tinnitus). So, maybe give your ears a rest from time to time.
What is the loudest Bluetooth speaker?
The Soundboks (Gen. 3) is the loudest Bluetooth speaker out there right now. Not only is it a large, weighty speaker, but it packs a serious punch in the volume department too, thanks to two newly upgraded 10-inch 96dB woofers and a 104dB compression driver tweeter. It dishes out 40 hours of playback per charge and features Bluetooth 5.0 for a smooth connection between your device and the speaker.
If the size (and price) of the Soundboks is too much, Amazon's Echo Studio is not only tuned to deliver rich, crystal audio at volumes of up to 90dB, but the stylish design means it would look at home in any room, while built-in Alexa voice control built-in is a welcome bonus.
How we test the loudest Bluetooth speakers
Bluetooth speakers can be for the living room or portable – either way, we need them to be able to play hellishly loud without complaint.
The biggest challenge when it comes to testing Bluetooth speakers has got to be their low frequency response. Can they do justice to deep growls and thunderous bass? A quick blast of Motorhead's Ace Of Spades will usually tell us what we need to know. Does Lemmy’s bass sound dirty but tight? Do Phil Taylor’s machine gun beats knock you back on your boot heels? What we don’t want to hear is a confused mash of noise.
We also listen for ‘presence’. Bluetooth speakers can sound monophonic, with all their energy emanating from the same physical space. What we value is a wider soundstage, whether this is achieved through clever digital signal processing or an inventive driver/passive radiator configuration, it doesn’t really matter.
Finally, to assess their treble performance, we inevitably fall back on Do It Again by Steely Dan, which remains a challenging soup of electric piano, cymbals and soaring vocals.
