JBL Xtreme 4 Bluetooth Speaker — gSport Silicone Sleeve (Black)

Powerful, room-filling audio from the JBL Xtreme 4: two woofers and two powerful drivers work together with dual pumping JBL Bass Radiators to produce dynamic, immersive sound. The speaker includes a gSport silicone sleeve in Black for added protection and grip. A built-in power bank lets you charge your devices while music plays — and a quick 10-minute fast charge delivers an additional 2 hours of listening time. For bigger sound, stereo pair two Xtreme 4 speakers using Auracast, or link the Xtreme 4 with other JBL PartyBoost-enabled speakers. AI Sound Boost continuously analyzes the incoming signal in real time and pushes the drivers to their maximum capability for optimized performance.
