JBL Boombox 4 Blue

JBL Boombox 4 Blue — Like New, Boxed & Receipt

Only used a few times and in immaculate condition. Full original set, box, power cable and Harvey Norman receipt included. Still within the original 2-year warranty period.

Bought it while my car had weak speakers. My car’s sound system is now fixed, so I no longer need it.

Fantastic sound: deep, punchy bass, clear vocals and powerful, room-filling audio. Perfect for home listening, BBQs, camping and parties.

Key features:
• 210W RMS on mains / 200W on battery
• AI Sound Boost and two Bass Boost modes
• Up to 28 hours’ playback, or 34 with Playtime Boost
• IP68 waterproof and dustproof
• Bluetooth 5.4, Auracast and JBL Portable app EQ
• USB-C lossless audio, phone charging and replaceable battery


Asking €399. Harvey Norman price: €499, checked 8 October 2026. Very little room for negotiation. Any checks welcome.
