Description

Choose your favorite bass sound with the JBL Boombox 4 Squad. This Bluetooth speaker has a Bass Boost button with 2 bass settings. You can choose Deep Bass for clear beats or Punchy Bass for tight bass. The speaker is waterproof, so rain isn't a problem and you can clean it under the faucet. Thanks to the 28-hour battery life and 6 hours of JBL Playtime Boost, you can keep listening for days. This way, the sound stays powerful when the battery is almost empty.

A top portable speaker with wonderful bass

Good sound
Deep bass
Tough!
Striking design must appeal to you

Sometimes products are simply good, and this one is no exception. A truly impressive device to behold. With a simple press of the Bluetooth button, it pairs with your phone in seconds. Playing Eefje your favorite playlist is a breeze, and then the party can begin. The music is crystal clear, and the birds, in particular, come through beautifully. Of course, with the first banger, you can already hear the bass rumbling through the room. With the double bass boost function, you can hear it go even lower and deeper. Truly amazing. Personally, I thought the lighting behind the exclamation marks on the subwoofers was a nice touch.

This makes this speaker stand out in both sound and appearance. I can highly recommend it. A fantastic piece of technology that you can carry around in your hand.

Powerful speaker with the typical JBL sound

Powerful sound with deep bass
No sound/bass distortion
Long battery life
8 kg is quite heavy

I was able to properly test this speaker at a pool party. The sound carries far in open air. The bass is deep and the battery lasts a long time. However, at full power with bass boost, it doesn't last as long. You do have to plug it into the wall socket to charge it, though it doesn't charge much at maximum volume.

Because then all the energy goes to the sound instead of the battery.
