✅ Why Choose Refurbished?

● Dual-Battery Reliability — The Stage 520 features two slots for JBL Battery 400 packs. We test both slots for charging speed and discharge stability. Since these batteries are modular, you can always add a brand-new second pack later to double your runtime.

● Precision AI Tuning — Our technicians verify the AI Sound Boost calibration, which optimizes the dual 7-inch high-sensitivity woofers to deliver deeper bass than the older 310/320 models.

● ✨ LED Matrix Re-Certification — We perform a full diagnostic on the expanded starry light show and the light-trail effects to ensure your visual performance is flawless.

● Heavy-Duty Inspection — The telescopic handle and wide, rugged wheels are stress-tested to ensure they can handle the unit’s 48-lb weight across pavement, grass, or sand.
