The Loudest Portable Bluetooth Speakers (and The Best)

loudest portable speakers

Are you looking to buy the best loudest portable speakers? Here at LoudestPortableSpeakers.com, we have made it our goal to research, compile, and inform the public on the loudest speakers available!

By contacting manufacturers, pouring through technical information, and listening to these products, we have discerned the list of the best speakers on the market today. Our definition of best as follows: loud, quality of sound, price, and other features specific to the speaker. But before we dive straight in, let’s look at some interesting factors to consider first.

How to Choose the Loudest Portable Speakers

loudest portable speakers

Before we share the loudest Bluetooth speakers you can purchase right now, there are some important factors you’ll want to consider to make the best choice for you. Don’t worry, because we’ve got you covered with an easy-to-follow guide below.

Battery Life

In an ideal world, you’ll have hours of battery life when using your portable speaker. Battery life is one of the most important factors to consider when choosing the best portable unit right now. It’s not ideal to recharge your speaker after each time you use it, or even during use. When researching the loudest Bluetooth speakers, there’s an apparent link between the size of the speaker and how many hours of use it offers.

For example, smaller units only require small batteries so they don’t last for hours of use. On the other hand, larger units can last up to 24 hours non-stop before they need to be charged. Generally speaking, an average portable speaker will last around four hours before you have to charge it again.  During your search, we recommend looking at the type of batteries your chosen speaker required. For example, Li-ion batteries need charging before you can use your speaker so consider if this suits your lifestyle, such as using the speaker for a daily routine or if you randomly have the urge to use it.

Audio Quality

The best loudest portable Bluetooth speaker won’t just have an incredible volume range, but high-quality audio, too. You can purchase a speaker that reaches a loud volume, but the quality becomes distorted as the volume increases. Consequently, we recommend looking for a total harmonic distortion below 1 percent, as well as looking into the frequency response.

The reason why some speakers sound better than others is because of the frequency range. Specifically, look for 100 Hz to 20 kHz to find the best option for you. This incredible range means that your speaker can reach high and low notes without any difficulties. Most of us can’t hear up to 20 kHz, so the top frequency range isn’t as important as the low points. This is particularly true if you like listening to songs with bass.

Style and Size

The best speakers on the market will also look stylish, too. When you like how something is designed, you’ll use it more often and feel proud when it’s on display. During your search, you’ll likely discover that Bluetooth speakers have a wide array of sizes, which can make the search more confusing but provide you with numerous options. Generally speaking, the larger the speaker, the better the stereo sound, but this does affect how portable the speaker is.

Style helps to make your speaker look luxurious, but the style and design can enhance the audio quality, too. Rectangular speakers direct the sound forward, making them ideal for a small room. Alternatively, cylindrical types are an ideal purchase for larger rooms as they redirect the sound in a wider range.

Waterproof Feature

Waterproof Bluetooth speakers are great because you can store them near water and they won’t break. Usually, water and electronic devices don’t usually work together, but we’re impressed that these two features can be combined and work well together. There are even some portable speakers that can be put under water and still work, though this is not a common feature and you’ll have to pay extra for this.

Smartphone Connectivity

Some Bluetooth speakers have more features than simply playing your audio. For example, you can receive phone calls through the speaker without even having to touch your phone. Many speakers on the market also have a microphone incorporated in them which is a useful feature so your conversation is aloud. Although, for some, this isn’t an ideal feature because people can hear what you’re talking about.

Choose From These Loudest Portable Speakers

We are going to kick off the reviewing process with the best portable speakers currently on the market and use it as a basis of comparison. There are many incredible devices to choose from, but we recommend considering the above factors to ensure you’re only purchasing the best one for your needs.

The Marshall Stanmore

loudest portable speakers Marshall speaker

The Stanmore is also the most expensive speaker in our comparison, but it brings some impressive features to the table. With dual .75 inch tweeters (located in the top corners of the unit), a 5.25-inch woofer (located centrally), and an 80-Watt amplifier, this speaker is capable of producing crisp highs with deep and powerful bass notes. It can produce frequencies from 45 Hz all the way to 22,000 Hz, meaning it is able to produce tones at the lowest and highest points audible to the human ear.

The Marshall unit offers three separate tuning features: Volume, Treble, and Bass. This allows the end user to customize the sound coming from the unit to their specific preferences. Turning all three to 10 will produce a wall of sound similar to what you could expect from an entry level sound system, while still maintaining the audio quality.

The unit has a sensitivity of 99 dB (100 MV at 10,000 Hz), which puts it at the top end of our roundup. Obviously, the battery life of the Stanmore cannot be discussed here as it doesn’t have one and relies on AC power. The Marshall unit does offer an RCA input (red and white wires you plug into your old TV), an Optical port, a 3.5 mm input (same as a modern cellphone, iPod, or similar audio playback device), and obviously Bluetooth capability.

X-Mini Me

loudest portable speakers x-mini-me

Here, we have the incredibly tiny and cylindrical X-mini Me, which measures in at 1.75″ tall and less than 1.5″ in diameter. X-Mini is based out of Singapore with distributors in over 80 countries; the miniscule X-Mini Me features only a $23 MSRP!

It cranks out over 80 dB of sound, which is four times quieter than the AC powered Marshall, but for being over 100 times lighter, 19 times cheaper, and incalculably more portable we will accept this small issue.

These bad boys can be linked together to create a multi-speaker system (boosting sound intensity) and the fact you can fit a bunch in your pocket, making them by far the most portable in the roundup.

They feature 6 hours of audio playback through the 1.5 Watt, 31 mm magnetically shielded driver. The frequency range is not as broad as the Marshall’s, only 200 – 20,000 Hz, but such a small driver cannot physically generate as low of tones as a 5.25″ subwoofer. As a result, you will lose something on the low notes and likely elsewhere too.

All in all, the X-Mini Me turns out some quality loudness for the price, but if you have more money to spend look toward our other options.

Soundmatters FoxL Dash 7

loudest portable speakers soundmatters-foxl-dash

The Dash 7 is one impressive unit. It features a thickness of just .75 inches (two iPhone 4s stacked on top of one another) and is only 7.5 in long, 2.13 in wide, and only weighs roughly 7 ounces. It is quite pocket sized and offers a convertible case (think iPad Smart cover) to allow it to stand on the edge and has speakerphone capabilities.

Sound quality is immensely impressive as it can dish out between 95 and 97 dB at half a meter away. Two 25mm (~1”) drivers and a passive woofer offer up a better frequency range than the X-Mini, of between 70 and 20,000 Hz. This will lead to a thicker sound than the smaller Singaporean product, but this is expected with the sizeable price increase.

A 12-hour audio playback (at roughly 76 dB), micro USB charging port, 3.5 mm audio jack, and incredibly knowledgeable reps on the support side all make this unit an incredible offering! The Dash 7 can also be paired (through audio jacks or wirelessly) to Soundmatters’ separate woofer, the foxLO (detailed more later on with the foxL V2). If it is on the expensive side of your budget, they offer the “Dash a” a scaled-back model (decreased battery life, thicker, and a few other metrics) for about a hundred dollars less!

Bose Soundlink III

loudest portable speakers bose-soundlink-iii

Bose needs no introduction in this sort of roundup. Founded by an electrical engineering professor at MIT, Amar G. Bose, the company opened its doors in 1964 and has since been making some of the highest quality audio equipment in the industry!

The Soundlink III is the newest in the incredible Soundlink line up and has some serious shoes to fill. Fortunately, Bose has the technical chops to back it up and has found a way to stuff two high-level drivers, two mid-level drivers, and a subwoofer all into the 10”x1.9”x5.2” Bluetooth compatible speaker. With all of this crammed into such a small box, audio quality and volume are both pretty amazing.

14-hour battery life, over 90 dB volume, 3.5 mm aux jack, and warm, full sound all make this product one of the best in the industry. However, a DC jack (instead of a micro USB) for charging and large price tag kept it from taking top honors in this category.

Jawbone Jambox

loudest portable speakers jawbone-jambox

The Jambox, by Jawbone, is another big name in the portable-speaker realm. Its (more) attractive price tag coupled with impressive output (over 90 dB) and a very nice design lead to its place as second in our line up.

The Jambox features a frequency diversity of 85 to 20,000 Hz and utilizes a pair of passive subwoofers and dual drivers. It offers 15 hours of playback, and once the battery is drained, it can be recharged with the ubiquitous micro USB standard cable.

The audio quality is there, but it is not quite what you will get from the Bose nor from the original Marshall. However, the color choice, price, and functionality made it stand out from our other top offerings.

Soundmatters FoxL V2 + foxLO Duet System

loudest portable speakers FoxL V2 foxLO Duet System

Soundmatters knows how to build a high-quality product! The foxL DUET system pairs the foxL V2 (which by itself is a very cool product) to their bass boosting foxLO unit. These two are capable of being tethered physically (with a 3.5 mm aux cable) or wirelessly (both via the Bluetooth protocol) and together allow a frequency range from 30 Hz all the way up to 20,000 Hz.

This is a more encompassing range than our original Stanmore, which is impressive from a battery powered system! The V2 utilizes 2 25 mm drivers and a passive radiator while the bass has a “Linear Magnetic Driver,” dual passive radiators, and provides 30 watts of amplification.

The two units offer over 12 hours of audio playback and a max volume of over 95 dB. Also the notable (unpaid) endorsement of Black Flag singer Henry Rollins, in numerous positive reviews, compact size, and usage of the micro USB standard led to the foxL Duet system to the top of our review for the portable systems.

Jawbone Big Jambox

loudest portable speakers jaw bone speaker

This speaker is, obviously, a larger version of the already well accepted Jambox. It utilizes twin 2.2-inch full range drivers as well as two 2.2 x 3.8-inch passive woofers. With its larger drivers, this Bluetooth speaker is able to turn out 60 to 20,000 Hz and a reported maximum of over 100 dB. This makes it the loudest portable speaker in our roundup.

It also features 10 hours of playback, which is very respectable considering its large size, as well as a micro USB charging port and a traditional 3.5 mm aux cable (in addition to the Bluetooth compatibility). All of these features make it a fantastic unit to fill larger rooms and for occasional transportation.

JBL Lifestyle Xtreme 2 Portable Bluetooth Speaker

loudest portable speakers JBL lifestyle

This is one of our favorite loudest portable speakers on the market right now, purely due to its design. Specifically, the speaker comes with an inclusive strap which you attach around your shoulder to conveniently carry it around with you. This strap is also comfortble to wear and a great way to transport the speaker on your travels.

Another admirable feature of this Bluetooth speaker is its tough design. The grille is sturdy and mainly designed from a nylon fabric along with chunky rubber elements that make this speaker resistant to water.

This JBL speaker comes with an array of handy features to improve your listening experience and usability. For example, the buttons on top of the speaker make it easy to access and you can also connect multiple speakers to this one device to enhance the volume even further.

Get your friends to purchase one, too. The Xtreme 2 version of the JBK speaker allows you to talk to the speaker without the need of a remote control. Simply press the button at the top to use this feature; this is handy if you’re in a busy situation and are awaiting an important phone call.

The JBL unit is one of the loudest portable speakers on our list and a great purchase. The balance between bass and treble is incredible and completely unexpected for such a reasonable price. Also, the bass is powerful, deep and impressive, and drums and guitars carry many realistic qualities to them to make it feel like you’re a part of a live performance.

One of the main reasons this speaker has such an incredible audio quality is that the speaker is larger than most portable units on our list. The sound refrains from distorting, even at high volumes. There’s also a slight edginess we love.

Jabra Portable Speaker

loudest portable speakers jabra

This waterproof, Bluetooth speaker has many incredible qualities to it. First, we appreciate that you can connect it via USB or Bluetooth to suit your needs. It’s lightweight and compact, making it ideal for transportation, and you can use it for personal use or answering important calls in a conference meeting.

The speaker claims to offer 15 hours of battery power, which is adequate time for the average user. Speak 510 offers high-quality audio – whether that’s throughout music or phone calls, and it even comes with a built-in microphone where you can connect with multiple people in one conversation.

This is probably one of the most exciting loudest portable speakers as it allows you to connect to Siri or Alexa. You’ll need an app to connect these to your speaker, but this is free and easy to follow. The app is worth downloading anyway because it offers additional features such as personalizing the device and adjusting voice functions.

The speaker has a unique design, as it’s exceptionally thin. Decorated with buttons on top, these feature an LED style light so they’re easy to spot and use.

The Jabra Speak 510 offers a clear voice to ensure that everyone is definitely heard during conference calls. The microphone on the top of the unit can sense sounds all the way around the room. Its Bluetooth range offers up to 100 meters, which provides you with ample room if you’re in a room full of people. We’re also happy to report that the Bluetooth signal is strong and won’t lose connection throughout using the speaker.

Infinity One Premium Wireless Portable Speaker

loudest portable speakers infinity one

This Infinity One portable speaker fills a large room with ease. Although it might be one of the smallest loudest portable speakers in this article, its audio quality is one of its best features. Specifically, the speaker has a wide range of audio to offer, making it great for numerous music genres.

Its Bluetooth connection is strong and reliable, too, as you can take it over 20 feet away from its source – even through walls – and its connection will stay strong. Use the speaker for 10 hours at a high volume, without experiencing any draining issues.

Plus, you can use the integrated battery to charge your smartphone once it’s fully charged. Bear in mind that this will decrease the speaker’s battery but it’s a great way to keep your phone fully charged.

One of the best aspects of this portable speaker is its cylindrical design that enables the sound to direct all around the room. It’s also nice to look at and pleasantly produces a thudding bass to your favorite tracks.

When you increase the volume, the sound doesn’t become unbalanced like some of the other loudest portable speakers available right now. It remains committed to eliminating any distortion, making it great to use at an outdoor scenery or perhaps when lots of people are talking around you.

JBL Charge 4

loudest portable speakers jbl charge 4

Another Bluetooth speaker with high standards is the JBL Charge 4. Thanks to the large dual drivers, this portable speaker delivers a mighty punch and provides a deep, sustainable bass, all the while without running the battery to the ground. If you use the recommended 7500mAH battery, the Charge 4 speaker can last up to 20 hours before it needs recharging. We’re also a huge fan of the USB output that enables you to charge your smartphone, or other devices, while you’re on the go.

Built with Bluetooth connectivity, you can connect a range of devices to this Bluetooth speaker, including smartphones, tablets, laptops, and everything in-between. Plus, the wireless speaker will still confidently work up to 10 meters away and once you’ve successfully paired the devices, you won’t believe the exceptional sound quality the Charge 4 produces. If your chosen device doesn’t have Bluetooth or it’s struggling to connect for some reason, the AUX input cable also offers a wired connection for these moments.

When you first glance at this speaker, it doesn’t look that different in comparison to the Charge 3, but there are a few minor details that have improved since previous designs. For example, the Charge 4 is bigger and more rounded, but this additional weight (an increase of 165 grams) means it produces a thicker bass. You should still be able to store the speaker in your backpack while you’re walking it, although it’s not suitable for holding during your travels.

On top of the speaker are various playback buttons slightly embossed compared to the Charge 3. Towards the bottom of the Bluetooth speaker are five LED lights that notify you of the speaker’s battery. There’s also a rubber flap that protects all ports should the device come into contact with water.

Sony SRS-XB12

loudest portable speakers sony srs

The Sony SRS-XB12 Bluetooth speaker is relatively small compared to other designs on this list, making it a great device to transport on the go. In typical Sony style, this speaker is equipped with a plastic frame that feels like rubber, making it look luxurious and remain practical for accidental drops. Plus, the wire-mesh that covers this unit is strong and helps to protect the speaker from any impacts. However, although this Sony speaker might be small, it certainly delivers an exceptional punch once you switch it on.

The buttons on the top of the speaker are firm, though not too difficult to press. You also don’t need to worry about this Sony device coming into contact with water because it’ll still remain intact. We’re not sure how it would perform if you drop it in a pool, but rainwater doesn’t have any impact on it.

The speaker doesn’t get as loud as some of the others on this list, although it can still fill a medium-sized room, making it great for small gatherings in your home or if you live in an apartment. However, if the volume is essential to you, purchase another Bluetooth speaker and you can pair them up for a louder and vibrant sound. Underneath the metal mesh material, you’ll find a monaural speaker at the top that is responsible for pumping the thump in the bass, while the passive bass radiator at the bottom of the speaker enhances the sound even further. Our absolute favorite feature of this Bluetooth speaker is that no matter the volume you use, there’s also a balanced sound to the high and low frequencies and no distortion whatsoever.  Plus, even when this Sony unit is set to a low volume, you can still hear clarity in voices and details in instruments.

Dali Katch

loudest portable speakers dali katch

Dali Katch comes with many features that make this one of the best loudest portable speakers available right now. For example, the aluminum woofers and two soft-dome tweeters help to enhance any audio you’re listening to and the Class-D amplifier attributes to the powerful delivery of music. Not only does this speaker fill a medium to large-sized room, but the sound seems powerful and present no matter where you are in that room. The thumps are colossal and there’s a presentable dynamic that fills the environment you’re in. 

If you look at the top of the speaker, you’ll find a power, volume, and pairing button that are all easy to use and responsive. Even the process of connecting your chosen Bluetooth device to the speaker is swift. Unlike some of the loudest portable speakers on this list, Dali Katch also features an EQ button that provides two placement options for freestanding the device or setting it on a table. This additional feature shows that your speaker’s location has a huge impact on the overall sound quality.

Katch lets you enjoy music for longer, as once it’s charged, the speaker will last up to 24 hours of continuous use. While you’re playing music, you can connect your smartphone to the USB port and it’ll charge your battery at the same time. Plus, for a party atmosphere, you can wirelessly combine two speakers at the same time so the sound can travel farther into the room. But, we understand that audio quality is more important than volume, which is why this Katch speaker features two profiles: Clear and Warm. Clear is a great profile setting for listening to live acoustics, while Warm provides more bunch and is great to enhance bass.

Harman Kardon

loudest portable speakers harman kardon

Harman Kardon includes an array of LED lights under the front fabric to notify you when the incorporated Google Assistant is activated and listening to you. We love that appearance of this speaker and its unique shape makes it stand out from the rest of the loudest portable speakers on this list. It’s not designed to hide on a shelf, but have its own sport reserved in a special place in the living room so everyone can see it when they first enter the room. But it’s still petite and elegant to not be in your face or require re-organizing your home.

One flaw about this Harman speaker is that you can’t charge other devices while it’s in use, but it does excel in other areas. For example, the Bluetooth technology is a handy feature for streaming apps as well as connecting your chosen device to listen to music. Also, with the aid of Google Assistant, you can use this speaker to check the weather or ask any on-the-spot questions without scrolling through your smartphone. With six microphones built into the speaker, it’ll concisely hear your voice every time. Plus, the microphones are sensitive enough that you can speak to the unit without being up close to it. 

Bass is definitely this speaker’s best feature, and although the low frequencies are still powerful, they don’t quite deliver an in-depth sound like bass does. It offers weight to any song you listen to, and the richness makes it great for playing heavy electronic music, too. In total, there are only two active drivers pushing the sound, and the volume is more powerful than the Sonos One. Therefore, you can use the Harman Kardon in a party setting and have no problems with people getting up on their feet.

UE Boom 2

loudest portable speakers ultimate ears boom 2

UE Boom 2 is designed to last a long time and is more durable than the previous model. The mesh fabric coating feels durable and protects the speaker from accidental drops and any water or dust entering the speaker. If you’re new to Bluetooth speakers, you’ll require something that is easy to use, and the UE Boom 2 is exactly that. For example, the port flaps sit at the speaker’s base and are easy to open when you need access to charging or wirelessly connecting to your device. 

The most noticeable and beneficial feature of the audio is the 360-degree sound performance that is capable of filling a room. Although UE Boom 2 might look small, the sound is big and fresh so there’s no need to worry about not hearing the audio if you’re sat at the other side of the room.

Connect the speaker to the UE Boom app where you can adjust the volume, bass and use the equalizer effect to your liking. You’ll also use the integrated app to link two or more speakers over Bluetooth for double or triple the sound. Plus, you can use the UE Boom 2 as an alarm to wake up to your favorite song every morning. Also via the app, you can adjust how the speaker responds to your requests. For example, incorporate the tap controls that mean you simply pick up the speaker and tap it to change track. This neat feature is one of the ways Boom 2 has improved from its previous model. 

Aiwa Exos-9

loudest portable speakers aiwa exos-9

We’re so excited to present this Bluetooth speaker to you because Aiwa installed five drivers into this incredible speaker. This includes two midrange woofers, two tweeters, and one subwoofer, so you’ll never experience low-quality sound again. Compared to the above speakers, this is the most powerful by far and for a reasonable price, too. This combination of speakers produces a clear, balanced and powerful sound to make it one of the best loudest portable speakers available right now.

Although the sound is something to brag about, this speaker also has an incredible battery life, but you can also purchase an extended battery to further increase the battery for times when you’re running low. The Exos-9 comes equipped with a USB port so you can charge your phone or tablet while listening to your favorite songs. Plus, use the EQ controls to customize your audio settings to your liking. With the choice of two audio modes – including Dual Stereo and Stereo Separated – you can select the best mode for your preferences. For example, Dual Stereo is great for a loud sound, while Stereo Separated separates the audio into two speakers so you can hear the details in your favorite songs.

Finally, the bass is powerful while remaining controlled as you increase the volume. When listening to middle frequencies, you’ll hear every detail of the song, while the highs are crystal-clear. Switch the EQ presets on to emphasize details even further and adjust the settings to suit your preferences. All the while, there’s little to no distortion and the bass doesn’t take over the middle ranges even when being played at maximum volume.

B&O Play 1

loudest portable speakers b&o play 1

B&O Play 1 is well-made and you can position it at any angle, and it’ll produce the same quality sound. As a result, this is great for keeping the speaker in a tight space and positioning it in fun angles. Plus, the leather straps make it a portable device and means you can also play music while walking around with it. If you prefer, you can even hang the speaker while it’s powered on and it’ll still work just as good as on a table.

Expand your options when listening to music by downloading the B&O Beoplay app. Via the app, you can connect numerous speakers to increase the volume and power, plus you can increase the bass to produce more power during your favorite tracks. The app is also great for adjusting sound styles, such as changing the bright, warm and relaxed tones to suit your mood. Or if you’re searching for guidance, you can use the presets and recommended options to assist you.

The B&O speaker features a built-in microphone, meaning you can retrieve phone calls if the speaker is connected to your phone. Plus, the audio quality is impressive so you’ll always properly understand what people are saying. But, the reason why you purchase one of the loudest portable speakers is for the audio performance, not just the additional features. This B&O unit is more powerful than you’d expect for its size and the balanced middle-range frequencies are clear, well the treble remains smooth and consistent throughout.

So Which Of These Loudest Portable Speakers Is The Best?

All of these speakers allow for high-quality playback, high volumes, and a certain amount of portability.

The best system would have to be the Marshall Stanmore, as it gives the best audio experience, but its lack of mobility and high price range make it ineligible for this roundup.

There is no absolute winner out of the seven systems outlined above, as each has its own personality as well as their own pros and cons, which we have done our best to describe. We will not assign an overall winner, as the true winner will be the end customer if they decide to buy any of these systems.

So enjoy your new speaker and use your new found power wisely! Have any of the above speakers caught your eye? Share your thoughts in the comments to keep this conversation going.
