The JBL Boombox 4 is down to $449.95 (originally $549.95) on Amazon. That’s the lowest price it has hit so far, according to price trackers.

This is the follow-up to the Boombox 3, and JBL hasn’t tried to reinvent it. Instead, it builds on what already worked. You’re still getting a large, portable speaker meant for outdoor use, with a few updates aimed at keeping it current—including Bluetooth LE audio and Auracast support. This makes it easier to connect multiple speakers or stream more efficiently if you’re using newer devices.

This is a speaker built for long days outside. It’s lighter than before, though still not something you’ll forget you’re carrying, and the plastic handle makes it easy enough to move around a backyard or take to the beach (even if it doesn’t feel as premium as the older metal one). Where it works well is durability and battery life. You don’t have to worry about dust, splashes, or even dropping it near water thanks to its IP68 rating. The battery is also rated for up to 40 hours, which means you can go a couple of days without thinking about charging (although your mileage may vary). Being able to replace the battery instead of the whole speaker is a nice touch.

Sound is tuned for impact. There’s plenty of bass out of the box, and you can push it further with a dedicated Bass Boost button or adjust things through a seven-band EQ. It gets loud, but at higher volumes, the sound can start to compress, and depending on where you’re standing, it won’t always sound as consistent. If you already have the Boombox 3 (now 40% off), this probably doesn’t give you enough to justify upgrading unless the longer battery life or newer connectivity features matter to you. For everyone else, this is a solid option if you want something loud, durable, and built to last.
