The JBL Go 4 is cheaper than a tank of gas at $39.95

The JBL Go 4 is one of those Bluetooth speakers that you can’t help but love because it was designed to go with you anywhere, and right now you can pick it up for a lower-than-normal price thanks to Amazon’s early Black Friday deals. Normally, this speaker retails for $49.95, but Amazon has knocked the price down to $39.95, which, for many, is going to be cheaper than a full tank of gas at the pump. We’re not saying you should spend your gas money on this speaker, but at least you’d have something to stream your music to.

The JBL Go 4 has lots of nice features, but one of the best ones is its ability to link up with another JBL speaker, and you end up getting stereo sound. This can be another JBL Go 4 speaker, or any JBL speaker that has Auracast.

Since this is a Bluetooth speaker, it does have an internal battery that will need to be recharged. However, the battery life on the JBL Go 4 is pretty decent. You should be able to get about 7 hours of playtime out of it before you need to plug it in. There’s even a Playtime Boost feature that extends the time by another 2 hours if you need it.

The JBL Go 4 is also waterproof, making it a great option for poolside parties, beach outings, or anywhere that it could accidentally get wet.
