JBL Pulse 4 Waterproof Portable Bluetooth Speaker - 360 LED Lightshow

Our review of the JBL Pulse 4 finds it best suited for people who want a party-ready portable speaker that combines robust sound with an eye-catching 360-degree lightshow. The single biggest reason to buy is the combination of JBL Signature Sound with a high-resolution LED display that reacts to music, creating an immersive audio-visual experience for small gatherings, poolside use, or evening outdoor events. Battery life and waterproofing mean it delivers practical portability as well as style.

Key Features

• 360-degree LED lightshow: A high-resolution, wraparound light display provides synchronized visual effects that match the music for lively atmospheres.
• JBL Signature Sound: The 360 degree speaker array delivers balanced sound in every direction so music fills a room or outdoor area reliably.
• Wireless Bluetooth streaming: Connect phones, tablets, or other Bluetooth-enabled devices up to about 40 ft away for convenient, cable-free playback.
• IPX7 waterproof design: Fully waterproof construction lets you use the speaker at pools, beaches, or in light rain without worry.
• Up to 12 hours battery life: A single charge provides extended playtime so the lightshow and music last through parties and gatherings.
• JBL Connect App support: The app allows changing sound-responsive colors and patterns and can link other PartyBoost-compatible speakers.

Who It's For

The Pulse 4 is ideal for social users who want entertaining visuals as part of their listening experience - people who host small parties, enjoy outdoor get-togethers, or want a stylish speaker for evening use. Its waterproof rating and portable battery make it a good choice for poolside or beach days where resistance to splashes and brief submersion is important.

Those seeking ultra-detailed audiophile performance or compact, pocket-sized portability should look elsewhere; while the Pulse 4 offers solid JBL sound and good bass for its size, its focus is on balanced, room-filling playback combined with the visual lightshow rather than studio-level neutrality or the smallest possible footprint.
