The Boombox Bluetooth speaker follows JBL’s fundamental design principles in utilizing plastic and fabric to style a water-resistant speaker, which looks to be an extra-large model of whatever the company has established. It is a thick 11.6-pound cylinder held together with a sturdy handle, so we weren’t banging that on our shoulders.

The heft makes sense when considering how big the unit. Measuring 10 x 19.5 x 7.7 in height, width, and thickness, it is the reverse of diminutive.

Design JBL Boombox

Two passive radiators flank the device, providing a bit of visual flair within an otherwise monochromatic tone. The cylinder itself houses the double 20mm tweeters, powered by two 4-inch woofers, all symmetrically laid out beneath the grille.

Keeping it simple, there are just a few buttons on the front: electricity, Bluetooth, quantity up/down, and play/pause. Both are connected to the cellular device’s controls.

Thus there isn’t any precise volume control when paired with all the JBL waterproof Bluetooth speakers. Lacking track bypassing buttons, we needed to double-tap play/pause to proceed forward a course. The Connect+ button will be for pairing with other JBL waterproof speakers in the stereo.

On the trunk, JBL comprised the power adapter, 3.5millimeter Aux-In, two USB interfaces, and a micro USB interface for firmware updates. Believe it or not, JBL does not contain any sound cables compatible with those ports from the box. None. There is a power adapter, clearly, but that is it.

There’s a built-in mic for voice calls, and the body is IPX7-rated, which means it stays underwater in clean water for as much as half an hour. As you’re unlikely to do so, you’ll feel assured that water or rain splashes from the pool are not likely to tame this item.

The JBL Bluetooth speakers Connect program for iOS and Android speeds up the setup but is not otherwise essential to conducting the Boombox. You may use it to change between Indoor and Outdoor manners or Party and Stereo, which is only appropriate if you have paired the Boombox with other JBL speakers Bluetooth.

One problem we found was that there were no equalizer or custom sound profiles to customize the noise somewhat, something we would have liked to watch at the price point and something you’ll be able to locate on similarly priced speakers.

We analyzed that the Boombox in an Indoor manner, and trust us, packs lots of bass without the additional drive Outdoor style provides. On paths with extreme sub-bass content, such as The Knife’s Silent Shout, the Boombox delivers an insanely strong bass response.

At the top, quite loud volume levels, the bass does not distort, although JBL deploys digital signal processing to narrow the lows out marginally at high levels.

At medium, regular listening volumes, the bass existence remains quite extreme. If you’re searching for a portable speaker that seems like it’s a built-in subwoofer, this is just the one to purchase. Those two woofers provide lots of thumps, and you may anticipate the Boombox to spin walls and scattering surfaces on heavy bass tracks.

Bill Callahan’s “Drover,” a course with little in the way of heavy bass, gives us a better feeling of this Boombox’s entire sound touch. The drums get more bass thickness than they want.

This is not the most precise sound signature you will find. But many listeners may love the noise. There is some critical depth to the drums, although, despite their hefty existence, the track includes a robust general equilibrium. Callahan’s baritone vocals acquire a few healthy, wealthy low-mid existence.

However, the high-mids and highs are also rather sculpted, providing his voice a few treble crackles and retaining the assault of the guitar strums and more significant percussive strikes clear and bright.

This is certainly not the right touch for everyone seeking a precise representation of the combination. It seems more like a club PA system, and a good deal of listeners will be thrilled.

About Jay-Z and Kanye West’s No Church at the Wild, the kick drum loops have a few enormous additional thumps, beefing up its sustain, while the sub-bass synth strikes that punctuate the defeat have been delivered with gusto, too.

Interestingly, the drum loop’s thump rather than the sub-bass synth strikes that sound strongest throughout the Boombox. It is generally the other way that the drum loop will seem strong but has more high-mid strike to it than bass thickness, but maybe not here.

Luckily, JBL retains the high-mids and highs clear, and items stay pretty balanced, with apparent vocal deliveries, which manage to avoid sounding too sibilant or be overpowered by the bass.

Orchestral tracks, such as the opening scene from John Adams’ The Gospel According to another, Mary, seem lively and extreme through the Boombox.

Purists might scoff at the fostering here, which adds a bass and body existence to the lower enroll instrumentation. Still, the greater enroll metal, strings, and vocals continue to be the principal attention, plus they get a bright, clear presence. This is a sculpted audio touch, but it preserves a balance between highs and lows.

Sound Quality

As stated before, the speaker includes two audio modes, one for indoor use, another for the outside. The outside mode rams up the sound spectrum’s low-frequency component, which leads to mind-boggling levels of mid-bass.

Total audio quality, however, is a bit of a mixed bag. On the flip side, it provides a fantastic bass response, from the sub-bass rumble into the mid-bass slam.

Contrary to other Bluetooth speakers I have examined, the JBL’s bass response is a raw, bodily thump you may feel in your chest, mainly once you crank this up. Along with the speaker, the total output is loud, thunderous. It is the ideal speaker for small to moderate outdoor parties.

On the other hand, the sheer quantity of bass that thing kicks out does have adverse side effects. The mids are brightly and pushed back, which means vocals are not too lively and eventually become somewhat lost. At precisely the same time, but the highs will also be somewhat tender so that the horn lacks zing and depth.

The JBL has forward-firing drivers, and therefore you don’t get a 360-degree sound just like you do use all the UE Megablast. However, the broad soundstage is unsatisfactory: it is narrow and somewhat prohibitive despite the sideways-firing woofers.

Device separation is feeble, also, with more demanding tracks sounding muddled and mixed up. Rivals like the UE Megablast and the Dali Katch are a good deal more precise and provide a lot more precise sound.


The JBL Boom box is assumed to function as the speaker folks gather around. It may entertain one. However, it is best used when serenading many. When it comes down to falling more than 400 on a speaker, it could be achieved for the ideal reasons.

We can not suggest the Boombox as a speaker to your house. It’s possible to discover similar sound in form variables that take up less property; however, if your strategy is to strike whatever terrace, patio, shore, or tailgate party you may find, then that one must be in the running to play the songs.
