What you need to know about the JBL Boombox 3

• JBL Boombox 3: $499.95 USD / $599.98 CAD / £499.99 / €579.99

The JBL Boombox 3 is a large portable Bluetooth speaker, with a handle on top so you can carry it around. It’s quite heavy, weighing in at 6.7kg. The speaker comes in two colorways: black or camouflage. As is the case with most JBL speakers these days, the Boombox 3 is IP67-rated for water and dust resistance, so it can withstand submersion in one meter of water for 30 minutes. This way, you can take the speaker to the beach or the park without issue, and even rinse it off if it gets dirty.

The speaker contains one subwoofer, two midrange drivers, and two tweeters. They all face forward, while dual passive radiators project from either side of the Boombox 3. You can feel the passive radiators moving when there’s a lot of low-frequency content.

The speaker connects to your device via Bluetooth 5.3 and uses the SBC codec. You can also plug in your phone through the 3.5mm port in the back to play music via a wired connection, and you can charge your phone using the USB-A port beside that. The speaker can also be plugged into a wall, so you have a constant power supply. If you want to use it wirelessly, the battery life of the Boombox 3 is 24 hours, according to JBL, and it charges in 6 hours and 30 minutes.

There’s also software for the speaker. The JBL Portable app is available on iOS and Android, and it will let you install software updates, adjust your EQ, and connect other speakers using PartyBoost mode.

What’s good about the JBL Boombox 3?

The JBL Boombox 3 sounds good, and it gets very loud. Turning it up high doesn’t make the audio sound bad, so it’s a solid option if you need a louder speaker for parties. It’s very bass-heavy, but that might be a good thing, depending on your tastes. If it isn’t a good thing, the JBL Portable app has an equalizer that will let you turn the bass down (or turn it up if you want even more). However, if you’re not interested in EQing your devices, don’t worry—the bass isn’t overwhelming by default, and the speaker actually sounds quite good. For example, when I listen to Dance Yrself Clean by LCD Soundsystem on the JBL Boombox 3, the bass is enjoyably loud without overpowering the percussion, vocals, and synths throughout the track.

The JBL Portable app is straightforward to use and includes a helpful user guide for the speaker in case you don’t want to dig around for the manual that comes in the box. There’s not much to it other than the three-band equalizer, software updates, and user guide, so it’s not a bloated or complicated app.

This speaker’s IP67 rating is an excellent feature since it means you can take it most places without worrying about damage. The back has a rubber flap to cover the AC, USB, and 3.5mm ports, so make sure that’s closed if you’re going to get it wet or dusty. Lastly, the controls on the speaker are easy to use and respond quickly.

What’s not so good about the JBL Boombox 3?

The first negative is the price: it’s high. The JBL Boombox 2 was the same price before, but now it’s $100 USD cheaper, which feels a lot more reasonable but also steep nonetheless. Another noticeable issue I have with the JBL Boombox 3 is how large and heavy it is. I definitely struggle to find space to store it in my small apartment, and it’s not the easiest object to carry around. The handle helps, but if you plan to lug this speaker around with you, you may struggle a bit.

The JBL Boombox 3 apparently has Bluetooth multipoint, but I can’t get it to work. I can’t connect two devices to the speaker at once—when I try, it just disconnects from the first. This results in a clunky switching process, as opposed to the smooth, fast switching multipoint usually brings with it. The issue is the same regardless of what kind of device I use.

Lastly, while the app is useful overall, the equalizer is really simple and doesn’t allow for more granular EQ customization. It’s only a three-band equalizer, and it doesn’t specify frequencies beyond “bass,” “mid,” and “treble.” It would be nice to have more specific customization options and presets to choose from.

There’s a lot to know about the JBL Boombox 3, so here’s a list of the specs you might want to know about.

JBL Boombox 3 review: Should you buy it?

The JBL Boombox 3 is definitely a great Bluetooth speaker since it’s loud, sounds good, and has some customization available for the sound profile. The biggest hangup I have is the price—it just feels high for what you get—but this is a solid choice if you don’t mind shelling out for it.

If you want a much more affordable Bluetooth speaker with an IP67 rating, the JBL Charge 5 is one of the best out there. It’s small, portable, sounds great, and has the PartyBoost feature for pairing multiple JBL speakers together for room-filling power. It’s available for $149 at Amazon. You can learn more about the Charge 5 in our video below:

If you want something a bit closer in form factor to the Boombox 3, consider the JBL Xtreme 4.  (on the product's website) It’s still large but much more portable. Along with an IP67 protection rating and a similar robust build, it offers swappable battery packs and a carrying strap, making it a bit easier to carry around than the Boombox 3.

If you want something a bit closer in form factor to the Boombox 3, consider the JBL Xtreme 3. It’s similarly IP67 rated and has the same features as the Boombox 3 and aforementioned Charge 5. It’s still large but much more portable, weighing only 2.68kg, and it also has a carrying strap, making it a bit easier to carry around than the Boombox 3. You can pick it up for $279 at Amazon.

The Anker Soundcore Boom 2 Plus ($249.99 at Amazon) is also worth a look. This speaker offers stereo playback, decent bass response, an IPX7 protection rating, and even cool built-in LED lights that pulse in sync with your music. It’s an excellent party speaker that can offer a little something extra at your next gathering.
