Top 5 LOUDEST Bluetooth Speakers in 2025

For almost twenty years, our knowledgeable audio staff has been evaluating the top Bluetooth speakers. If you need evidence, read our review of the Parrot DS1120 Bluetooth Speakers, which serves as a reminder of our extensive testing methodology and the length of time we have been evaluating and ranking portable audio.

We simply have extensive knowledge of Bluetooth audio. With the support of a group of professionals whose names you can find in the ‘tested by’ section at the end of this guide, I have been a full-time audio reviewer (and now editor) since 2019. You can rely on our judgment because all of the speakers have undergone extensive, practical testing.

Naturally, ultra-portable speakers have their limitations; they aren’t designed to produce deep, room-filling bass. No Bluetooth speaker the size of a stack of coasters can compete with a set of stereo towers, let’s face it. That’s not the point, though. Portability is the main focus of these small companions, and we have identified the best available in terms of sound quality, battery life, usability, and overall value.

Look no further than our top waterproof speakers if you require something more durable. Check out our list of the top wireless speakers for high-quality sound that connects to your home’s WiFi. Otherwise, enjoy the music and continue reading.

Top 5 LOUDEST Bluetooth Speakers in 2025

1.Soundcore by Anker Boom 2

Last update on 2025-03-11 / Affiliate links/images from Amazon.

Many of the features that made the Motion Boom so popular are still present in the Anker Soundcore Boom 2. It has a similar waterproof, floating design and a large bass sound, to which it adds entertaining LED lighting and a louder maximum volume. We would have preferred a better build, but it’s a great choice for pool parties at night. The Boom 2 is a better choice if you want a Bluetooth speaker with a louder sound and a light show, but the JBL Flip 6 is even more portable and robust.

Approximately 7.3 by 11.7 by 4.0 inches (HWD) and weighing 3.7 pounds, the Soundcore Boom 2 comes in Adventure Green, Explorer Blue, or Phantom Black (the color I tested). On either end, there are two striped LED panels that serve as passive bass radiators. For convenience, a built-in handle extends across the top. The plastic exterior of the main enclosure is a little unimpressive in both appearance and feel. The Flip 6 and many other rival outdoor speakers use a more sophisticated matte silicon material. For comparison, the Flip 6 weighs 1.2 pounds and measures 7.0 by 2.6 by 2.8 inches, making it significantly lighter. In contrast, the Sony SRS-XG300 weighs 6.6 pounds and measures 12.5 by 5.4 by 5.4 inches, making it twice as large.

The 2.1 speaker system is shielded by a perforated plastic grille on the front. A central 50W woofer and two 15-watt (W) tweeters provide a total output of 80W. This is an amazing setup for a portable speaker, even though the latter part isn’t big or strong enough to be a true subwoofer. Please be aware that the overall output drops to 60W if the Bass Up mode is turned off. Either way, to match deep bass tracks, the passive radiators on the ends vibrate enthusiastically. The frequency range covered by the three drivers is 45 Hz to 20 kHz. In terms of connectivity, you get Bluetooth 5.3 and just the default SBC codec.

Power, Bluetooth, minus (volume down), play/pause, plus (volume up), TWS (to connect another Boom 2 speaker to form a stereo pair or up to 100 other Soundcore PartyCast-enabled speakers), Bass Up, and other physical buttons are all located on the control panel. Along with answering or ending calls, the play/pause button also allows you to navigate tracks (press twice to go forward, three times to go backward) and call your device’s voice assistant (press and hold). Although I wish there was a button to toggle or otherwise control the LED lights, the controls are responsive and easy to use.

On the back, a snap-shut cover protects a USB-C port for the included USB-C-to-USB-C charging cable and a USB-A port for charging other devices. Feet on the bottom help with grip and prevent deep vibrations from moving the speaker around on hard surfaces.

As long as the rear hatch is sealed, an IPX7 rating allows you to submerge the speaker for 30 minutes at depths of up to one meter. The benefit of this rating is that heavy rain, pool splashes, and sink rinses are not dangerous, even though Bluetooth won’t function underwater. The Soundcore Boom 2 is perfectly safe to use near a pool because, as previously stated, it even floats. Comparatively speaking, the IP67-rated JBL Flip 6 is dustproof, which makes it better suited for beach and camping excursions.

2.Bose SoundLink Home

Last update on 2025-03-11 / Affiliate links/images from Amazon.

No matter where you place it, the Bose SoundLink Home is made to look elegant. It feels like a long-lasting piece of hardware, fitting the Bose brand, thanks to the build quality. The metal frame of the speaker serves as a stand and extends underneath the bottom. Textiles cover the main body, and design elements made of nylon and plastic are also present. It comes in gray or black. The black model was sent to us for testing.

The speaker measures 4.3 by 8.5 by 2.3 inches (HWD) and weighs 2 pounds. It’s easy to move around your home, though it’s a bit heavy to toss into a bag and carry around. The Edifier is much bigger, comparatively, at 6.4 by 9.8 by 7.0 inches and 6.7 pounds; it’s meant to stay at home.

The left side of the SoundLink’s frame houses a USB-C port, which is used for charging and USB audio. On top, a selection of physical controls runs from one side to the other. The controls include a power button, a Bluetooth button, a volume rocker, and a multi-function button for controlling playback. Press the multi-function button once to play or pause audio, twice to skip forward, or three times to skip back. You can also use the speaker for calls. One press of the multi-function button will answer or end a call, while a press-and-hold declines an incoming call.

The Bose SoundLink Home connects wirelessly through Bluetooth 5.3 and supports multipoint pairing to connect two sources. You can also connect your audio source directly via the USB port. The speaker has only a single driver, and Bose doesn’t disclose its size or frequency range.

The speaker has a few noteworthy omissions despite its high-end appearance and feel. First and foremost, it is incompatible with all types of Wi-Fi connections. This implies that you cannot add it to a collection of wireless speakers in a multi-room system or stream music to the speaker from services like Spotify Connect. Additionally, it is incompatible with voice assistants such as Amazon Alexa. In addition, the speaker is not waterproof and does not have an IP rating. Even using it in the restroom is discouraged by Bose. Finally, it is incompatible with the Bose app, which would enable customization by allowing you to change the EQ or reassign buttons.

Stereo Mode is a stereo effect that can be achieved by connecting two SoundLink Home speakers, but it requires manual button pressing. Holding down the main speaker’s Bluetooth and power buttons while simultaneously pressing the second speaker’s Bluetooth and volume down buttons allows you to pair with a second speaker in Stereo Mode. I discovered that using Stereo Mode in this configuration resulted in a buggy connection, even though you could connect your phone and a second speaker to the main unit. When I switched to a wired connection between my phone and the speaker via the USB-C port, the speaker-to-speaker connection stabilized and sounded better.

3.Bose SoundLink Flex (2nd Gen)

Last update on 2025-03-11 / Affiliate links/images from Amazon.

If you’re looking for a sleek, stylish portable Bluetooth speaker, you’ll struggle to find a better-looking alternative than the Bose SoundLink Flex Gen 2. This small speaker assumes a compact, curved form with a durable rubber body and attractive metallic-looking grille. But it’s more than just a pretty face.

The Bose SoundLink Flex Gen 2 plates up impressively powerful audio for its size, with commendable levels of detail and surprisingly good instrument separation. As a result, you get a layered, clear listening experience that will keep you tuned into your favorite tracks for hours on end. Sound quality can get a touch harsh and unstable at top volumes, but for the vast majority of the time, it steers well clear of tinniness and distortion.

The treble is delicately and delicately communicated, and the mids sound as rich as you could expect from some of the top Bluetooth speakers in this weight and size range. Bass has good depth and dynamism as well, even though it doesn’t have the same impact as a large party speaker. Unlike its original generation predecessor, the Bose SoundLink Flex Gen 2 allows you to change the EQ settings. Simply download the Bose app and adjust the settings to your preference. You will probably need to manually adjust audio using the app’s three-band equalizer because there aren’t many presets (four that increase or decrease either bass or treble).

However, the SoundLink Flex Gen 2 offers not only a powerful audio performance but also outstanding durability and build quality. With its IP67 dustproof and waterproof rating, this Bluetooth speaker can withstand being submerged in a meter of water for 30 minutes. Quite remarkable. Its sturdy exterior, covert feet that keep it upright, and a customizable shortcut button—which I personally used to activate my voice assistant—are additional features. This truly is the whole package in terms of design.

And even in the features department, the SoundLink Flex Gen 2 has a solid amount to work with. Of course, the Bose app opens up a lot of this, including the aforementioned EQ settings and shortcut button customization. But it also enables you to view devices connected via multi-point, change auto-power off time and even name the speaker from a list of random names (mine was Pint Size Party). And like its first generation ancestor, the SoundLink Flex Gen 2 harnesses PositionIQ tech, which optimizes audio output depending on the speaker’s orientation.

While the re-use of PositionIQ is commendable, it does highlight an indisputable feature of the SoundLink Flex Gen 2. It resembles the original Bose SoundLink Flex quite a bit. It has a similar sound profile in addition to having nearly the same appearance. The most annoying thing about the newer model is that it only has a 12-hour battery life, which is a little disappointing considering that more recent competitors, such as the Beats Pill, have much longer playback times.

Nevertheless, a more recent Bluetooth version and the inclusion of EQ settings are a discernible improvement. Do owners of the original SoundLink Flex need to upgrade? Maybe not. However, this is unquestionably a very good choice if you’re looking for a new Bluetooth speaker. Therefore, I would suggest this speaker if you’re new to the SoundLink Flex line and want a fantastic portable speaker that works well in any setting. Otherwise, one of the options in our list of the top waterproof speakers might be more suitable for you.

4.Beats Pill

Last update on 2025-03-11 / Affiliate links/images from Amazon.

It is an oblong Pill that closely resembles the original, measuring about 2.8 by 8.6 by 2.8 inches (HWD) and weighing 1.5 pounds. The speaker is available from Beats in Champagne Gold, Matte Black, or Statement Red; I was given the latter two to test. The Statement Red edition is very eye-catching, but the Matte Black edition gathers dust easily.

The Pill has a matte silicone finish on the rest of the enclosure and a metallic front grille with tiny perforations. There are four tiny feet on the bottom to keep the speaker steady on flat surfaces, and a detachable, color-matched lanyard fastens to the right side.

The Beats Pill has a single neodymium tweeter and a racetrack-style neodymium woofer inside that work together to create mono sound. Beats does not share frequency range specifications, and the design does not include passive bass radiators. Unlike the original front-firing drivers, the drivers are positioned at a 20-degree upward angle, which enables more effective air displacement than previously possible.

The Pill does not support AptX or other Android-friendly codecs, but it does support Bluetooth 5.3 and the AAC and SBC codecs. The less potent Anker Soundcore Motion 300 provides LDAC in addition to AAC for better codec compatibility with Android devices.

On top of the speaker is the control panel. A power button, a status LED, a pinhole microphone, a multifunction button, and separate minus/plus volume controls are located from left to right. The battery status LED illuminates when you press the power button once, and the voice assistant on your phone is activated when you press it twice. The middle button can be pressed once to control playback, twice to skip a track, and three times to go back a track. Calls are also handled by the middle button. By default, a double press ends calls, while a single press answers or mutes calls that are already in progress. Using the Android app or the iOS settings page, you can change the mute and end call commands.

Despite being a mono speaker, the Pill can produce stereo sound when two units are paired in Stereo Mode. In what Beats refers to as Amplify Mode, you can also pair two for louder playback without setting up a stereo pair. The buttons provide access to these modes. To activate Amplify Mode, press the central button on both speakers at the same time. To switch from Amplify Mode to Stereo Mode, press and hold the central and plus buttons on one speaker. This speaker will then be the left channel of the stereo pair. Holding down the center and minus buttons at the same time will disconnect the connection.

5.Sony LinkBuds Bluetooth Speaker

Last update on 2025-03-11 / Affiliate links/images from Amazon.

Although Sony has released a number of speakers over the years, the new LinkBuds Speaker is the first to be released under the LinkBuds brand. The original Sony LinkBuds were unique in that they had open-ring designs that allowed you to stream music and hear your surroundings, but the name now seems to refer to a variety of lifestyle audio options rather than that specific open design, so here we are.

When I review products like the Sony LinkBuds Speaker, I frequently have to get past name-whingeing early so that I can concentrate on compliments about the device for the remainder of the review (and because I love a good name-whinge).

The charging cradle, which was my favorite feature of the entire speaker, best illustrates that. It serves as a hub from which you can quickly remove the speaker when you’re pacing into another room and charges the speaker when you’re not using it.

However, there is more proof that the LinkBuds Speaker is introverted. It blends in well with your home’s decor thanks to its subtle design, but it’s not as durable as the best waterproof speakers. You can use it as an ersatz home assistant (at least with your phone) thanks to its microphone, and a number of other features like hourly time alerts and a programmable musical alarm clock all suggest that this device is meant to be used indoors.

With a surprisingly large 25-hour battery, you won’t be left behind if you take it outside, but you might not find the audio suitable for summer cookouts or parties. This is especially true of the audio, which is rather directional and falls short of some competitors in terms of energy and vibrancy. If you’re searching for a party speaker, the Sony will let you down.

The feature set that Sony provided pleasantly surprised me; its Sound Connect app has a number of useful features that I haven’t seen on competing devices, which is a nice touch.

That doesn’t mean you’ll be left in the lurch if you take it outside, especially with a surprisingly big 25-hour battery, but you might not find the audio fits parties or summer cookouts. That’s doubly the case with audio which proves quite directional, and doesn’t quite equal some rivals on the market in terms of energy and vibrancy – if you’re looking for a party speaker, the Sony will disappoint.

One useful feature is auto-play, so you can set your speaker to start auto-playing from Spotify, Amazon Music or Endel at certain times on certain days, basically like an alarm clock. In my testing, I was unable to choose which playlist Spotify auto-played from, and it default to carrying on whatever I last listened to, but the writing in the app suggests that I should be able to pick them. Hopefully a software update will change this.

The speaker has a quick access button, which I will go over in the Design section of this review. You can use the app to map this to either Spotify Tap, Amazon Music Play Now, or Endel Quick Access. Each of these options will display a carefully selected playlist from the app of your choice. As you can see, Sony’s app only supports these three apps. I’m sorry, Tidal users, but you can use other streaming services to play music on a regular speaker. The additional features are simply inaccessible to you.
