Design & Build Quality of JBL Pulse 4
JBL has crafted the Pulse 4 with an eye-catching, cylindrical design that features a fully transparent LED panel covering most of the speaker’s surface. This 360-degree LED display delivers mesmerizing light shows that sync with the music, offering multiple customizable patterns via the JBL Connect app.
The speaker is IPX7 waterproof, meaning it can survive being submerged in up to 1 meter of water for 30 minutes—perfect for pool parties and beach outings. However, it lacks a rubberized base, making it slightly less stable on uneven surfaces. At 1.26 kg (2.8 lbs), it’s not the most compact speaker, but it’s still portable enough for travel.

Unlike its predecessor, the Pulse 4 delivers 360-degree audio with a strong bass response, crisp mids, and clear highs. The passive radiator at the base enhances the low-end frequencies, making it an ideal speaker for bass-heavy tracks.
While the Pulse 4 provides powerful and immersive audio, it lacks deep sub-bass and struggles with high volume distortion in some genres. The lack of a dedicated tweeter also affects its ability to deliver finely detailed high frequencies.
