This year's Amazon Big Spring Sale may be over, but there are still bargains up for grabs if you look in the right place. That's where I found this JBL Go 4 at Amazon for $39.95 (was $49.95), which is a great buy if you're in the market for a cheap portable speaker

While you can use the JBL Go 4 at home, its compact size and durability make it perfect for outdoor adventures. It's also stylish; you can choose from a variety of colors and patterns – from basic black to camo. This is the JBL Go 4's lowest price, and with how affordable it already is, I don't expect it to drop any further for a while.

JBL Go 4:was $49.95 now $39.95 at Amazon

The JBL Go 4 is back to its lowest price on Amazon. It offers plenty for the price, including a stylish, lightweight design, an IP67 waterproof and dustproof rating, and a battery that could last a full day trip. Specifically, it lasts seven hours on one charge and can add two more hours with its Playtime Boost feature. It's certainly more than capable of putting out some good sound, just don't expect high-end audio for this budget price.

In our JBL Go 4 review, we found this portable speaker has a lot going for it, including the "humble" price tag, lightweight and compact build, and IP67 waterproof and dustproof rating. It's waterproof enough to survive a temporary dunk in the pool and dustproof enough to sit on a sandy beach.
