JBL’s waterproof and dustproof Boombox 3 keeps the party going for up to 24 hours at $380 (Reg. $500)

$120 off/$380

Amazon is now offering the JBL Boombox 3 Portable Bluetooth Speaker at $380.23 shipped. You’d usually be shelling out $500 for this speaker at full price, which has been regularly spending time down at $400 throughout 2025. We did spot it dropping to $360 and $340 last month in Prime-exclusive deals, though if you missed out on those rates, you can pick it up today at the same price we saw during July’s Prime Day event. All-in-all, this is a 24% markdown that cuts $120 off the going rate and lets you go BIG with all your portable audio needs.
