JBL Charge 6
Score: 86/100
Marshall Kilburn III
Score: 83/100Rankings

The JBL Charge 6 is a rugged, feature-rich Bluetooth speaker with AI Sound Boost, 28-hour battery life and IP67 waterproof, dustproof and drop-proof durability. Its heavy weight and bulkier size, plus the lack of an included charging cable, are drawbacks. Perfect for outdoor parties and users who need a built-in powerbank.

The Marshall Kilburn III is a premium portable Bluetooth speaker delivering 50 W of tri-amp power and up to 50 hours of playback, highlighted by its robust IP54 construction and analog controls. Its considerable weight of 2.8 kg and ambiguous power-bank functionality are notable trade-offs. Ideal for users seeking loud, long-lasting sound in a durable, amp-styled design.
