It looks the same, but the UE BOOM 3 has a subtle redesign that makes it more portable than ever.

Waterproof Bluetooth speakers are all the rage nowadays, but one of the first companies to get it right was UE with its Boom series. While the original Boom and even the Boom 2 were good, we weren’t as impressed as everyone else was given the price. With the newest UE BOOM 3, though, there’s hope again: it’s actually competitively priced at around $150 USD (and often even less). So, is the UE BOOM 3 any better than previous versions?

Editor’s note: this UE BOOM 3 review was updated on June 24, 2021, to include more product information and update formatting.

Who should get the UE BOOM 3?

  • Beachgoers or people in rainy climates will appreciate the IP67 rating. I lived in the Pacific Northwest for a year, and when they say it rains every day they aren’t lying. If you live in a part of the world where it rains all the time, waterproofing all your things isn’t a luxury. It’s a necessity.
  • People who like the JBL Charge 4 but want something more portable will appreciate the UE Boom 3’s size. While the Charge 4 is a great speaker for the price; plus, it comes with some cool features. That said, it’s also pretty large. And while the built-in stand and bulging shape make it great for the deck or the yard, it isn’t as easy to bring around as the UE BOOM 3.

How is the UE BOOM 3 built?

It may not be the best sounding speaker, but the UE BOOM 3 still gets plenty loud.

The build quality of the speaker is solid and it got an entirely new makeover design-wise as well. The UE BOOM 3 is immediately recognizable as a UE product, but there’s a few things that are different now when compared to previous versions. Gone is the soft plastic bumper down the middle of the speaker that had the plus and minus buttons. Instead, it’s been replaced with a slimmer plastic strip down the speaker’s spine.

This might sound weird to say about a cylindrical speaker, but it’s also less rounded off. The edges end sharply and the entire speaker is shaped much more like a large soda can than the previous version. That design choice was intentional, as the UE BOOM 3 easily fits anywhere that a water bottle would—whether that’s in your bag, your car’s cup holder, or even the water bottle bracket on your bike.

The UE BOOM 3 still has the characteristic plus and minus sign buttons.

The UE BOOM 3 is also wrapped in an IP67 waterproof fabric that’s tough and grippy. I had no problems keeping a good hold on it even when it was wet and knowing that a rainstorm won’t be the end of it definitely adds some peace of mind when taking it outside. Even better, the UE BOOM 3 floats just like the Wonderboom, which is a small feature that packs a ton of value. It’s not just the outside that was made to be tough either: UE claims that the speaker is drop-proof, too. While we didn’t do any drop tests off a building, it did survive a roll off my bed without a problem, which is probably a more common scenario anyway.

The UE BOOM 3 still sports the signature plus and minus buttons for adjusting volume and three buttons up top for controlling playback and powering the speaker on/off. I had no problem with these buttons during my time with it because unlike the Charge 4, the buttons on the UE BOOM 3 are distinctive shapes. Even in the dark, it’s easy to feel around and find the one that you want. There’s also a small loop on the back to hang it but I found it too small to be useful for anything. Unless you attach a separate carabiner to it, it’s pretty much useless.

Does the UE BOOM 3 have a microphone?

No, the UE BOOM 3 unfortunately does not have a microphone either. If you tend to answer calls via your speaker this is something to keep in mind. While I doubt it’s a common occurrence for most people I’ve definitely answered calls while in the shower or while floating in a pool before, so I understand when someone says that it’s a must-have feature.

How’s the connection strength?

While we reviewed the bright blue model, the BOOM 3 is available in six colors.

Fortunately, the UE BOOM 3 doesn’t seem to have any issues with dropped connections or stutters. As long as you stay within ~50 feet there’s nothing to worry about. It even gets the job done at around 100 feet with no walls in the way. It doesn’t seem like many companies are having too many issues with Bluetooth connectivity in recent years, at least when it comes to staying connected.

Then, there’s the app which is both good and bad. It’s bad because I’m tired of downloading apps for everything I buy but good because it’s actually useful and adds functionality. For one, it has a basic EQ so you can tweak the sound of the speaker to your liking, but it also lets you save up to four EQ presets. That way, you can have one for when you’re listening to your podcasts in the shower (that can’t just be me right?) and another for when you’re at the beach with friends.

Up top are three buttons for controlling playback.

Besides that, the app is also where you go to connect to other UE speakers. You can connect up to 150 other UE speakers, and it’s backward-compatible, meaning the older UE BOOM 2 can take advantage of this. We couldn’t test this as we only had one speaker to play with, but it’s good to have the option if you and a few friends all have UE speakers. You can also use the app to turn the speaker into a musical alarm clock if you’re tired of listening to your phone every morning.

Then there’s a button that lets you switch between playlists without needing to reach for your phone. Of course, you’ll have to set this up in the app, but you’ll be able to skip between playlist by long-pressing the multifunction button in the middle for three seconds. Then controlling your music is just like anything, with a single tap pausing/playing and a double-tap skipping to the next song. Curiously, the ability to triple tap to return to a previous song is missing, which is kind of a bummer because otherwise the UE BOOM 3 would have everything.

How to pair to the UE BOOM 3

Its new shape is roughly the size of a water bottle, so you can take it wherever you go.

Pairing to the UE BOOM 3 is very simple. Just follow these steps to pair to your phone or computer:

  1. Quickly press the power button located on the top of your speaker to turn the speaker on.
  2. Then press and hold the smaller Bluetooth pairing button in order to enter pairing mode.
  3. Next go into the Bluetooth settings of your source device.
  4. In the available devices section, select “UE BOOM 3” from the list.

Can the UE BOOM 3 connect to Alexa?

Unfortunately, the UE BOOM 3 can not connect to Alexa anymore. UE speakers have been able to connect to Amazons’ assistant in the past but on its FAQ page the company stated that in an effort to make the experience better they discontinued the feature on Android. If you’re after speakers with Alexa make sure to check out our full list of Alexa-compatible speakers as you’ll likely find something there.

How is the battery life on the UE BOOM 3?

A small loop on the back would go great with a carabiner, though it’s too small for anything else.

UE claims a battery life of 15 hours, but in our testing, we got 8.3 hours which is a bummer. While it’s fine for an average day, it isn’t going to blow you away like some other, less expensive speakers that can play music for 24-hours straight. But again, UE made a slight change that I think is really cool: you can charge the UE BOOM 3 wirelessly with the proprietary Power Up dock. The caveat? It’s sold separately.

The dock has three pins that charge the speaker via a small metal divot at the bottom. I wish it came with the speaker, but it isn’t absurdly expensive at $40. Just keep in mind that if you take this speaker out with you for a long beach day, you’re going to have to throw back on the charger when you get home.

The UE BOOM 3 battery life falls very short of its listed playtime.

Another nifty feature is the ability to power up the UE BOOM 3 without touching it via a power button in the UE BOOM app.  What is a little disappointing is that both the speaker and the dock use micro-USB instead of USB Type-C. It seems like UE has a bunch of great, futuristic ideas for this speaker but it’s being held back from truly being future-proof by clinging to an old port. It obviously isn’t a huge deal, but it means that if you get the UE BOOM 3, there’s a good chance it might be the only device in your life that charges via micro-USB in a few years.

How does the UE BOOM 3 sound?

The UE BOOM 2 wasn’t our favorite sounding speaker in the past, and that hasn’t changed here. It still puts more emphasis on being loud than sounding good, but if you’re going to be outdoors at the beach or in the park, that might be what you’re looking for. For all of our listening, we didn’t alter the EQ in the app and left it as-is out of the box.

The first thing you notice when listening to music is that this speaker definitely puts the “boom” in UE BOOM 3 (I couldn’t resist). In all seriousness, the low end is emphasized, but the drivers aren’t big enough to do bass notes any justice. Instead, the bass in the song Daffodils by Mark Ronson sounds less powerful, almost like midrange frequencies, which means that it competes with vocals far too often and often ends up masking them.

The BOOM 3 doesn't reproduce accurate audio, but it's good enough for a get together.

Similarly, the high end doesn’t sound like there’s much holding it back, which results in distortion and harshness at high volumes. This is easy to hear in the song Horchata by Vampire Weekend; the bells and cymbals sound too loud compared to everything else. It’s worth mentioning that most of my issues seemed to be at volumes greater than 80 percent. At regular volumes, there aren’t too many issues but if you’re getting the UE BOOM 3, chances are you’re going to be pressing that volume up button a lot.

Should you get the UE BOOM 3?

If you don’t have another Bluetooth speaker or you’re looking for a quick and practical gift, then absolutely. Otherwise, there’s nothing wrong with shopping around a bit.

All prices listed in USD unless otherwise specified. Prices may change over time, and vary by region. Unfortunately, we cannot list Amazon prices on the site, as they vary greatly by currency.

The UE BOOM 3 isn’t the best sounding speaker by far, for that you’d probably have to go with the JBL Charge 4, but UE has made a lot of incremental improvements. The ability to link up to older UE speakers, the addition of wireless charging via the dock, and a redesigned body are all welcome changes. It seems the company took the time to think about how people are actually going to use this speaker, and that attention to detail combined with the lower price point makes the UE BOOM 3 an easy recommendation, even if it does charge via micro USB.
