✅ Why Choose Refurbished?

● Modular Battery Security — The Boombox 4 uses the JBL Battery 600 pack. Because it is user-replaceable, buying refurbished is incredibly safe; if the battery ever wears out years from now, you can swap it for a brand-new one in seconds.

● AI-Optimized Audio — Every unit is factory-reset to ensure the AI Sound Boost algorithms are perfectly calibrated to the dual 123mm woofers and 20mm tweeters for maximum volume.

● P68 "Life-Proof" Testing — We re-verify the seals so your refurbished unit can still handle being submerged in water or used in sandy beach environments.

● ⚡ Lossless Audio Verification — The USB-C port is tested to ensure it supports both 2026 standard high-res lossless wired playback and its power bank functionality.

⚡ Performance Highlights

● Unrivaled Power: Delivers 210W RMS (AC Mode) or 200W RMS (Battery Mode), making it significantly louder than the Boombox 3.

● Playtime Boost: Offers up to 28 hours of playback, which can be extended to 34 hours via the Playtime Boost feature in the JBL Portable app.

● Auracast™ Networking: Seamlessly broadcast to an unlimited number of 2024–2026 JBL speakers for a massive wall of sound.

● Dual Bass Modes: Includes dedicated Deep Bass and Punchy Bass settings to match the environment (indoor vs. outdoor).
