Product Review: JBL Boombox 3

The JBL Boombox 3 is a portable Bluetooth speaker that promises powerful sound, long battery life, and durable build quality. Packed with features, this speaker aims to be the life of the party and deliver an immersive audio experience. In this review, we will take an in-depth look at the sound quality, build quality, battery life, features, and styling of the JBL Boombox 3.

Sound Quality

The sound quality of the JBL Boombox 3 is impressive, delivering rich and deep bass with crisp highs. The dual JBL Bass Radiators on either side of the speaker ensure a powerful punch, providing a great listening experience for bass lovers. The overall sound is well-balanced, allowing you to enjoy a wide range of music genres. However, at higher volumes, there is some distortion noticeable, which can be a drawback for those who like to crank up the volume.

The speaker is also IPX7 waterproof, meaning it can withstand being submerged in up to 1 meter of water for 30 minutes. This makes it perfect for pool parties or beach outings. The buttons and controls on the speaker are well-placed and feel solid, adding to the overall build quality.
