JBL Boombox 2 bluetooth speaker test

The JBL Boombox 2 speaker is the perfect companion for outdoor parties.


Frequency response: 50Hz – 20kHz, equipped with 2 10.6cm midrange / subwoofers, 2 x 2cm tweeters, battery life on a single charge: 24 hours, weight 5.9 kg, speaker power: 80 watts. It delivers clear, distortion-free sound even at high volumes, and is IPX7-rated, which means it’s waterproof.

This portable speaker is specifically designed for outdoor use, accordingly with powerful bass capable of very serious sound performance.

JBL Boombox 2 design

This design of the JBL Boombox 2 is almost identical to the previous model. We discovered some small differences for that. There is an exclamation mark on one side of the JBL logo, there is a little extra colour on the bottom of the handle. The size and weight of the Boombox 2 is almost the same as its predecessor.


With two passive radiators, dual 20mm tweeters and two 10.6cm subwoofers under the hood to produce intense bass sounds. The buttons are arranged in much the same way as the previous model, except for a few minor changes. JBL has moved the Bluetooth button to another location, with the PartyBoost button in its old place. It also has play / pause and volume buttons, and LEDs on the bottom indicate battery life. Double-click to skip play / pause.

The rear ports also retained the same layout as the previous Boombox. Here you will find the AC adapter, the 3.5mm Aux-In, and the USB port for charging phones and other small devices, as well as the microUSB port. There are no cables in the box other than the AC adapter.

Connectivity and features

This model had a button called Connect + that, paired with other JBL speakers, played the same music at the same time – or in stereo. Unfortunately, this feature is no longer available and can only be paired with another Boombox 2 speaker, the PartyBoost button.

This time, the JBL also left the separate indoor and outdoor modes of the previous model. The manufacturer thought its sound quality sounded great in both environments and didn’t require switching between them. Unfortunately, there is no equalizer to adjust the speaker sound.

Although the Boombox 2 is a Bluetooth speaker, it does not support the two best codecs: aptX and AAC. Of course, we are aware that most Bluetooth speakers do not support both, but this speaker is quite expensive, so it would be expected.



The JBL Boombox 2 is IPX7 rated, making it ideal for use near splashing water and rain. It can be immersed in clear water for up to 30 minutes and can even float on the surface of the water.

It provides very serious volume and performance compared to its size, and the sound has not lost its clarity even when the volume has been increased. The bass is outstanding no matter what we listen to.

Like all speakers, the Boombox 2 has a point where the sound is already distorted and we have found that the distortion starts to settle around 80-90%. Keep in mind, however, that this is already very loud, so you probably only need to use such a high volume when a lot of people are gathering in a larger area.

We also tried Boombox 2 in a smaller studio and outdoors. Compared to being a small, portable speaker, it delivered quite a bit of sound performance. The acoustics of the studio were optimal, as the sound-absorbing and diffuser panels recommended during the acoustic design were placed on the walls and ceiling. In the corners, Giga sound-absorbing membrane panels were made by the studio owner, making the sound absolutely ideal. The acoustics of the interiors significantly affect the sound, so it is very important to handle the acoustics of the studio!

It sounded practically exactly the same as its predecessor. The tone is essentially the same and fills the larger spaces very well.

Battery life was also pretty much the same as before. The 24-hour estimate for JBL is only accurate if we adhere to the default volume, but even at 60%, we can easily reach 20 hours. The buzzing sound we experienced at the previous Boombox when the battery was low did not appear on this device, so JBL seems to have solved this problem.


Despite its small size, this Bluetooth portable speaker delivers very powerful and serious sound performance. The sound quality is excellent even outdoors, it sounds clear even at higher volumes. Compared to the previous model, neither external nor performance has changed much, but that’s not a problem either. Water resistance is also a major advantage, as neither rainwater nor water splashing from the pool will damage the speaker. The downside is that it can only be paired with another Boombox 2 speaker, not previous JBL models. The price is quite peppery, not everyone is going to spend that much money on a speaker for a holiday or a party. However, if someone does invest in a JBL Boombox 2 speaker — you won’t regret it because you’ll have fantastic sound even in noisy outdoors.
