The funky JBL Go 4 is back to its lowest price this year

Need a speaker you can take with you on the go? Right now, you can get the cheap but convenient JBL Go 4 at Amazon for $39.95 (was $49.95).

The JBL Go 4 doesn't cost much to begin with, so this discount is more like the cherry on top of an already good deal. The funky Bluetooth speaker is only 3.7 inches wide and three inches tall, which makes it easy to clip onto or fit inside a backpack or bag. As a plus, it comes in a variety of colors from plain black to bright red – it even comes in camo!

JBL Go 4 Portable Bluetooth Speaker: was $49.95 now $39.95 at Amazon

The JBL Go 4 is a budget portable speaker and is now down to a super-low price on Amazon. It packs plenty of value into its 3.7x3-inch body and can withstand outdoor activities in rain or shine thanks to its IP67 waterproof and dustproof rating. It can also last up to seven hours on a single charge. While that isn't much compared to JBL's other speakers, it's enough for a decent day trip. The built-in loop also makes it easy to attach to bags with a carabiner, too.

It's cheap and colorful, but that's not all. In our JBL Go 4 review, we highlight the IP67 waterproof and dustproof rating alongside its lightweight and compact size. That IP67 rating means it can completely block out dust and dirt and survive an accidental dip into the pool.

This is JBL's cheapest speaker, so its battery only lasts seven hours (compared to 12 hours for the JBL Clip 5), and it doesn't have as many features or as strong audio as pricier alternatives. Just keep that in mind: it's for fun, not forever.
