Portable Bluetooth speakers come in a variety of shapes, sizes, and prices, so it’s impossible to say that any one model is perfect for everyone. But we think the UE Wonderboom 2 has the best chance of delighting your ears without overly walloping your finances. This speaker has a full, clear sound and a compact design. It’s also waterproof and dustproof, and built to survive even the most adventurous vacations.
The UE Wonderboom 2 is as euphonious as Ariana Grande but as tough as Lara Croft. In our blind tests, our panellists picked this Bluetooth speaker as the best-sounding model for its price, with its especially clear vocal reproduction and a decent amount of bass for its size. It has an IP67 rating and is one of the most rugged Bluetooth speakers we’ve tested, able to survive a 5-foot drop and a dunking in 1 meter of water – but because it floats, it’ll probably never dive that deep. The Wonderboom 2’s only downside is its battery life, which, at eight hours, is adequate but not impressive. We like the Wonderboom’s cute, compact design, even if the almost-spherical shape makes this model a little tougher to pack away in a suitcase pocket or laptop bag.
If you want a portable Bluetooth speaker that approaches the sound of a good small stereo system yet is rugged enough to take almost anywhere, the JBL Xtreme 2 is a terrific choice. Three of our four listeners thought the Xtreme 2 was the best-sounding speaker we tested, praising it for its ample bass, high maximum volume, and overall clear, clean sound. It’s IPX7-rated, which means it can survive submersion in 1 meter of water, and it includes a handy, strong carrying strap. The Xtreme 2 also delivered 19 hours of battery life. But it’s much larger and pricier than the UE Wonderboom 2.
If you need something that sounds a little louder and fuller than the UE Wonderboom 2, but that’s more portable and affordable, even than the JBL Xtreme 2, the Sony SRS-XB32 finds a nice middle ground. It’s about twice the Wonderboom 2’s size, plays a little bit louder, and puts out a lot more bass. It’s also rugged, with an IP67 waterproof/dustproof rating. In our battery test, it automatically reduced its volume after about six hours of fairly loud use, but it played for about five more hours after that. It also has adjustable multicolour lights and flashing strobes, which don’t appeal to us – but somebody must like these things or manufacturers wouldn’t keep including them.
If you don’t want to spend a lot on an all-around good portable Bluetooth speaker, the Tribit XSound Go is a great choice. Its sound is obviously clearer and louder than that of almost all other budget Bluetooth speakers. The XSound Go is also small enough to slip into a laptop bag or an already stuffed suitcase, and it will run 10½ hours on a charge. Plus, it’s IPX7-rated, which means it’s sufficiently waterproof to survive a half-hour dunking in 1 meter of water, and it has a speakerphone function.
The EcoXGear EcoBoulder+ is a completely different kind of portable Bluetooth speaker than our other picks – it pumps out maximum volume for pool parties and picnics. Although it can blast, it can also soothe – not only with its full, natural sound, but also with a built-in bottle opener and cupholders. Weighing 29 pounds and sized like a roll-aboard suitcase, the EcoBoulder+ is not something you’ll take on business trips, but its retractable handle and wheels do make it easy to lug around. It also has a built-in AM/FM radio and a long battery life – 24 hours, in our test.
Who should buy a portable Bluetooth speaker
Anyone who owns a smartphone or tablet would probably enjoy owning a portable Bluetooth speaker, which can improve the listening experience anywhere. Bluetooth is available in every current smartphone and tablet, as well as in most laptop computers, so you don’t need additional equipment. Unlike smart speakers and Wi-Fi speakers, Bluetooth speakers don’t require a network connection and the use of special apps – whatever you play on the phone will play through the speaker.
Portable Bluetooth speakers have a rechargeable battery and are frequently waterproof or splash-proof, so you can easily move them around the house or take them to a park or the beach. We’ve found that they make hotel rooms feel more like home.
The best of these speakers deliver sound quality that’s good enough for casual music listening, podcasts and internet radio. Although Bluetooth does degrade sound quality slightly, you’re unlikely to hear the effects through relatively low-quality speakers such as these. If you’re worried about it, take the online blind test on my website and see what you think.
For true high-fidelity sound, we recommend a pair of decent bookshelf speakers and a stereo receiver or one of the top picks from our best computer speakers guide. You’ll get clearer sound, much better stereo imaging, and usually much deeper bass response. You can add a Bluetooth adapter if the system doesn’t already have Bluetooth built in.
Voice control of the sort popularised by the Amazon Echo and Google Home is uncommon in portable Bluetooth speakers, because almost all voice-command technologies require a Wi-Fi connection to function. Some Bluetooth speakers provide a button that activates your smartphone’s voice-command technology (such as Google Assistant), but because you can access those features straight from your phone, this isn’t a big advantage.
How we picked
I’d estimate that there are a couple thousand models of Bluetooth speakers now available, many sold under obscure brands and sometimes only through Amazon. Considering that new ones seem to appear every week, it would be impossible to find and hear them all. But we’ve listened to most of the major models and are always on the lookout for promising new models to test.
We use the following criteria to help us decide which speakers to call in for testing:
- Portability and battery life: Although any Bluetooth speaker can be lugged around, we focused on models that have rechargeable batteries and are designed to take a trip to the beach or the park with no hassle.
- Ruggedness and waterproof design: We gave priority to speakers that are built to survive the knocks and bumps of travel. Although we didn’t limit our testing to waterproof speakers, we did give preference in our judging to speakers with an Ingress Protection rating, which tells you exactly how waterproof and dustproof a speaker is.
- Price: Even though we would like to test every type of portable Bluetooth speaker, we set a bottom price. Bluetooth speakers are often available for very little, but we’ve never found an extremely inexpensive model to sound good enough to bother using – especially when the speakers built into today’s better phones can play loud enough for light listening.
- Playback controls: Because playback can be controlled from your Bluetooth source device (usually a phone or tablet), we didn’t require the speaker itself to have playback controls, but it’s a convenient plus.
- Special features: Bluetooth speakers offer all sorts of features beyond the ability to play audio from Bluetooth-sourced devices. These include speakerphone capability, pairing (the ability to play the same material through two Bluetooth speakers at once), built-in lighting, and even integral bottle openers. In polls and comments, every reader seems to have their own opinion as to which (if any) features are the most important, so we didn’t require any particular features when picking products to test.
After considering all of the criteria, we ended up evaluating 35 new models for the most recent update, including recent releases from 1More, Anker, Audioengine, Doss, EarFun, Heyday, Harman Kardon, JBL, Kew Labs, LG, House of Marley, Marshall, Monoprice, Sony, Tribit, Tronsmart, UE, VicTsing and Vifa. This brings us to a total of about 270 Bluetooth speakers that we’ve tested since this guide first posted.
How we tested
As has become my standard practice for updates to this guide, I started by giving all of the new models a long listen, connecting them via Bluetooth through my Samsung Galaxy S9 phone and playing the same four test tracks: pop, heavy metal, hip-hop, and jazz. I compared the speakers not only with each other but also with some of our previous picks.
I measured the maximum output of each speaker at a distance of 1 metre using an NTi Minilyzer audio analyser and a calibrated NTi MiniSPL test microphone. For this round of testing, I made one change from our past testing method because I noticed that my previous methods didn’t seem to accurately reflect the perceived maximum volume level in the speakers I tested. I speculate that this is due to the increasing sophistication of the internal limiters that protect the speaker drivers and minimize distortion. So instead of simply playing pink noise and noting the maximum decibel level on the audio analyser, I used the analyser’s Leq mode, measuring the average maximum level when playing ZZ Top’s very loudly recorded tune Chartreuse. Sometimes the result was a little higher than in previous tests, sometimes a little lower, but I think this approach will deliver a result that better reflects what you’ll hear in day-to-day use.
I narrowed the contestants to the models that I thought had a real chance to impress our listening panel, and I included a couple of past picks.
Although my personal audio tests were, by necessity, sighted (that is, I always knew which product I was hearing), I used a screen of thin black fabric to hide the identities of the products from the panelists. I first set the playback level of each speaker to 74 decibels, using the shaped-noise channel-balancing test tone recorded from a Dolby Digital receiver. Because of the widely varying performance, the coarse volume control steps, and the unpredictable actions of the volume limiters used in these speakers, it was impossible to match levels accurately, but in most cases I was able to get them within plus/minus 0.3 dB.
I played each panellist a mix of tracks known to be good tests of audio quality, such as Tracy Chapman’s Fast Car, as well as a couple of tracks of their own choosing. I concluded the test of each speaker by cranking it up as loud as it would go and playing a rock track, such as AC/DC’s Highway to Hell. We started with smaller models and moved up to larger ones, and I changed the order of presentation for each panellist.
I asked the panellists to note which speakers they liked best, paying particular attention to:
- how clear they sounded at normal levels
- the balance of bass to midrange to treble
- how loud they were able to play when cranked up
- how clear they sounded when cranked up
After the listeners gave me their opinions of the sound, I unveiled the speakers and got their comments about design, features and price.
I checked the battery life of each of our top picks by repeating Steely Dan’s Aja at an average level of 75 decibels (measured at 1 metre), over and over until the power ran out. Note that our results may not agree with the manufacturers’ stated battery life, likely because their testing methodology – which they almost never publish – varies from ours. I also measured maximum Bluetooth range of all our picks.
For models that offer speakerphone functionality, I tried placing a call with each model to Wirecutter senior staff writer Lauren Dragan, who has helped me evaluate speakerphone quality for years. I speak to her from the same place in my living room, starting with my mouth 2 feet from the speaker; then I note how she sounds to me, and she tells me how my voice sounds.
Our pick: UE Wonderboom 2
A portable Bluetooth speaker should be compact, rugged, affordable, and (most of all) good-sounding. The UE Wonderboom 2 ticks all of these boxes and then some. Three of our four panellists considered this model’s sound to be the best of any speaker we tested in its price range, and they praised its natural balance of bass to midrange to treble, as well as its clear reproduction of voices. The Wonderboom 2 is about the size and weight of a large apple, so it’s easy to carry around. It also has lots of useful features, including an Outdoor Boost mode that makes it louder (at the expense of bass), an ultra-rugged design, stereo/mono pairing, an extra-long Bluetooth range, and a top button that lets you pause and restart the music, as well as skip to the next track.
“The sound is surprisingly clear for such a small speaker,” said Sammy Velick, a drummer and one of our panellists. Lauren added: “It sounds bright, but it’s got enough bass to balance that out – it’s boom and sizzle, where most of the small speakers are all sizzle.”
With an IP67 rating, the Wonderboom 2 is dustproof and waterproof, and it can be submerged in up to 1 metre of water for a half-hour. It also floats, so you won’t lose it if you drop it off a boat or dock or into a swimming pool. UE says the Wonderboom 2 can withstand a 5-foot drop; we confirmed this by dropping it from 5 feet, first onto a hardwood floor and then onto concrete. Not only did it keep working, but it barely even showed a scuff mark. A small, elasticized strap on top lets you hang the Wonderboom 2 from a shower rod, tent pole, or other object, provided you have a carabiner, a hook or a strand of string to attach it.
In our measurements, the Wonderboom 2 put out 84.6 dB at 1 metre, about the same level you’d hear from the traffic noise if you were standing at a busy city intersection – and enough to fill a small room with sound. The Outdoor Boost mode increased this by about 3 dB – that’s not a dramatic boost, but it is noticeably louder. However, this mode reduces bass, so the speaker doesn’t sound as full and pleasing. Bluetooth range measured an impressive 95 feet through one window.
Flaws but not dealbreakers
If you like lots of bass, this probably isn’t your speaker. I was the only panellist who didn’t rank the Wonderboom 2 as the best speaker in its price range because I was bothered to hear its little speaker drivers choking on some of the deep bass notes in my favourite jazz and pop recordings. If you prefer a bit more bass, the larger Sony SRS-XB32 may be more to your liking.
The Wonderboom 2 lacks a speakerphone function. We wouldn’t use this feature often, but you might.
Battery life is rated at 13 hours, but we measured roughly eight hours, and that’s with four trials of two different units, with the Outdoor Boost mode disengaged. That’s adequate to cover a full workday, but there won’t be any reserve to save you if you forget to keep it charged.
Finally, though the Wonderboom 2 is light and compact, it’s not slim. Its cylindrical design, measuring about 3½ inches in diameter and 4 inches high, takes up more space in a suitcase than some slimmer designs and prevents it from fitting comfortably in a laptop bag.
Upgrade pick: JBL Xtreme 2
The JBL Xtreme 2 is easily one of the best portable Bluetooth speakers we’ve heard, with a big, full sound that approaches the quality of what you might hear from a good compact stereo system. Three of our four panellists considered it to be the best of all the speakers we tested in this (and probably every) round. The Xtreme 2 is a good bit bigger and heavier than the UE Wonderboom 2 and the Sony SRS-XB32, but its detachable shoulder strap makes it easy to carry to the beach or park. Because the Xtreme 2 carries an IPX7 rating, it can easily survive rogue waves or unexpected downpours.
“It’s the only one that had enough bass to sound good on Kanye West’s Love Lockdown,” Lauren said. “It has a 3D, spacious quality to the sound. Male voices sounded good, although the sound is a little bright, so it makes female voices sound a little harsh.” Sammy and I had similar comments; only our final panellist, woodwind player Dan Gonda, demurred, saying the bass was too pumped-up for his taste.
At 11½ inches long by 5 inches in diameter, with a weight of 5.4 pounds (more than four pounds heavier than the Wonderboom 2), the Xtreme 2 isn’t especially compact, and it definitely isn’t light – but thanks to its thick canvas shoulder strap, it’s easy to lug around. The strap even has a bottle opener built into its buckle.
Although the Xtreme 2 put out a relatively modest 89.9 dB at 1 metre in our tests, it seems far louder because the sound is so full and the bass really kicks. Battery life is rated at 15 hours, and we measured 19 hours in our tests. Bluetooth range measured an impressive 110 feet through one window.
There’s a speakerphone function – when I called Lauren, she described my voice as sounding “clear, but a little compressed”, but her voice sounded great on my end of the call. The Connect+ function lets you connect up to 100 Connect+ speakers together for mass playback (although that’s 98 speakers more than most people would probably want to connect). The play button on top lets you pause and restart playback and skip to the next track.
The Xtreme 2 has two real downsides. The first is that it’s expensive – around Rs 5,000 more than the current price of our previous upgrade pick, the Sony SRS-XB41. But three of our four panellists greatly preferred the sound of the Xtreme 2, so for listeners who want a very loud, clear, and full-sounding speaker, we expect it’ll be worth the extra cost.
The second downside to the Xtreme 2 is that it charges only through a separate AC adapter, which of course you’ll have to remember to bring with you if you want to play it for more than 19 hours. A speaker this big and powerful would charge much too slowly through a Micro-USB cable, but we wonder if switching to USB-C (as so many other Bluetooth speakers have done) might have been preferable.
Also great: Sony SRS-XB32
The Sony SRS-XB32 is the speaker to get when you need a bit more speaker than the UE Wonderboom 2 but not as much speaker as the JBL Xtreme 2. It’s about twice the size and weight of the Wonderboom 2, but it has a fuller, bassier sound that would make it a reasonable substitute for a small stereo system – and a better choice for use in a dorm room or bedroom. The SRS-XB32 also has a variety of features that we expect some listeners will think are awesome and others will think are silly.
“Overall, this one sounds very good,” Dan said. “The sound is well balanced between bass and treble, and it never sounds nasty, as some of these speakers did.” Lauren, Sammy, and I generally shared Dan’s sentiment: The SRS-XB32 won’t make you forget you’re listening to a compact Bluetooth speaker, but it’s satisfying for casual listening at home, small backyard gatherings, and sharing tunes with a few friends at the beach. The Extra Bass button lets you punch up the lows when you put on hip-hop, heavy metal, or taiko drum recitals.
The SRS-XB32 measures 9.3 by 3.1 by 3.2 inches and weighs 2 pounds – that’s a little too big to toss into a suitcase without a second thought, but small enough to toss into a car trunk or beach bag. Because it’s IP67-rated, it’s dustproof and waterproof, so there’s no need to worry if it encounters sand, splashes, or rain.
Like some of Sony’s other portable Bluetooth speakers, the SRS-XB32 has multicoloured lighting that can be adjusted through a smartphone app. We’re not particularly fond of this feature, but if you like this sort of thing, then you’ll like this sort of thing. The SRS-XB32 also includes Sony’s Party Booster feature, which produces various percussion sounds when you slap the speaker on the front, sides, top or bottom. I can’t imagine what kind of party might be enlivened by this feature, although I can attest that the sounds will stop a misbehaving shih tzu from doing whatever she’s doing.
Battery life is rated at 24 hours with Extra Bass off and 14 hours with Extra Bass on, but for us the battery life didn’t come close to Sony’s ratings. Even with Extra Bass off, the SRS-XB32 ran for only six hours before it automatically reduced its level to preserve battery life; it lasted another five hours after that. We saw this same behaviour in the SRS-XB32’s predecessor, the SRS-XB31, but unlike the SRS-XB31, the SRS-XB32 is still usable when it reduces its volume. So the SRS-XB32 will probably last through a day at the beach, but don’t forget to charge it when you’re done listening.
At full blast, the SRS-XB32 puts out 87.4 dB at 1 metre. That’s almost 3 dB more than the Wonderboom 2, but the Sony’s fuller sound makes it seem even louder. Bluetooth range measured about 50 feet through one window. You can connect up to 100 compatible Sony wireless speakers for synchronised playback. You can even sync the lights. The play and pause button on top lets you pause and restart playback and skip to the next track. When we tested the speakerphone function, Lauren reported that my voice sounded fairly clear and natural, but her voice sounded like she was speaking into a disposable plastic cup.
Budget pick: Tribit XSound Go
If you want a great all-around portable Bluetooth speaker for about the cost of a tank of gas, the Tribit XSound Go is a terrific choice. Sonically, it’s a step up from anything else we’ve heard in this price range, with clearer sound and more bass than most competitors can muster. This speaker is easy to travel with, too – it’s small enough to slip into a laptop bag or any suitcase. Plus, it’s IPX7-rated, which means it’s sufficiently waterproof to survive a half-hour swim in 1 metre of water.
When the XSound Go accompanied me through four weeks of travel, I continued to be surprised by how clear and full its sound was. Voices sound natural and distinct, never bloated or hoarse, as they can through most inexpensive Bluetooth speakers. The XSound Go doesn’t sound as full or play as loud as the Wonderboom 2, but all of the panellists thought it delivered amazing sound quality for its price. Measured maximum volume was 82.4 dB – not enough to get a party going, but enough for light listening in a typical living room.
There’s nothing flashy about the XSound Go, but it doesn’t have that cheap, plasticky look that many budget Bluetooth speakers have. Although it has a play/pause button on the top, it doesn’t have track-skip buttons, which would come in handy if you used the XSound Go in the shower. The battery is rated for 24 hours of life; we got only about 10½ hours, but for a budget Bluetooth speaker, that’s fine.
The XSound Go’s speakerphone function is good, especially for the price. I could hear Lauren very clearly, although she complained that my voice sounded slightly muffled. In our tests, Bluetooth range was about 25 feet through one wall, which is good for a speaker of this size.
Also great: EcoXGear EcoBoulder+
About two years ago, the “pool blaster” Bluetooth speaker category emerged: large models that have high volume levels and a waterproof design. Many people would love having a speaker like this for pool parties or tailgating, but the EcoXGear EcoBoulder+ is the first we’ve found that delivers the combination of volume and sound quality we’d been hoping for.
This is easily the best-sounding pool blaster we’ve heard to date, with an even balance of bass, midrange and treble that presents all instruments and vocalists naturally without calling attention to (or mangling) any one element of the music. The EcoBoulder+ is built much like a good home stereo speaker, with an 8-inch woofer below a 3-inch tweeter, and an 8-inch passive radiator in the back to reinforce the bass. The big speaker drivers and the built-in amp rated at 100 watts allowed the EcoBoulder+ to hit 104.1 dB in our tests, about 14 dB louder than the JBL Xtreme 2. That’s loud enough to cover a backyard. If the sound isn’t quite to your liking, bass and treble controls let you fine-tune it, but we never felt the need.
The EcoBoulder+ is also easy to cart around. With a retractable handle and built-in wheels, it scoots around just like a roll-aboard suitcase. Sturdy handles on top allow two-handed lifting. It’s IP67-rated, which means it’s waterproof and dustproof, and it also has a waterproof pocket on the side for a smartphone. A bottle opener on the side and two cupholders on top facilitate consumption of beer. This model also has a built-in AM/FM radio. A ¼-inch jack on the speaker’s side lets you connect a microphone (not included), so you can use the EcoBoulder+ as a little PA system. In the unlikely event that you need more volume, you can pair two EcoBoulder+ speakers for stereo sound.
Surprisingly, the EcoBoulder+ even has a speakerphone function, so if you ever need to do a conference call with 30 people while sitting poolside at a Florida resort, you’re good to go. Even more surprisingly, the speakerphone function is one of the best we’ve tested, with excellent voice quality at both ends.
A power socket lets you connect a standard AC cord for charging. Battery life is rated at 10 hours at full volume. Considering that few people will buy the EcoBoulder+ to play music at normal indoor levels, we ran our battery-life test with the volume set 6 dB louder than we did with the other models we tested (which in a normal living room sounds pretty loud). Even at this higher volume, the EcoBoulder+ ran for 24 hours on a charge. Bluetooth range in our tests was about 43 feet through one wall, enough that you could probably leave your phone indoors while the EcoBoulder+ played out by the pool.
One panellist summed up the EcoBoulder+ nicely when he said, “They obviously took a hard look at what a person wanting a speaker like this would need, and they put it all in there. And it sounds way better than anything similar we’ve tested.”
